Be based on an EPS solution that amounts to transducer

Summary: EPS special transducer is the stage amounts to the technical characteristic according to EPS industry, track the demand of EPS industry client closely, it is the transducer that EPS industry develops technically. Article key discusses a guest that amounts to transducer to make chemical Cheng design. Keyword: Torsion of EPS lash-up power source compensates transducer 1 foreword EPS (EmergencyPowerSupply) the abbreviate of English word head that is lash-up power source. EPS applies extensively at industry and civil building to wait happen to cut off the power suddenly the bear of main power supply that the accident can give normal production, life to cause significant pecuniary loss, it is the main component that modern building safety ensures establishment. EPS general situation is what use below emergency as fire control or production is mothball boost power supply. Be in the place such as bazaar of high-level building, bazaar, traffic of hospital, orbit, underground for example personnel much, outlet is little, natural illuminant is finite, when once appear,fire or electrified wire netting are destroyed, illuminant disappears inky, person much exit is little at the same time, brought consequence will be unimaginable. Because lack,at the same time fire control team is met power source is supplied and cannot deliverance of calamity of put to good use works, such more heavy the degree of calamity. Visible EPS produces mainer and mainer effect to the safety of modern society, be " urban lifeline system " Palladium. The control means that at present EPS uses and control method are different, the load that takes in the light of EPS place can induce 3 kinds: It is the EPS that basically is used at lash-up illume and emergency lighting; 2 be besides lash-up illume, emergency lighting, the three-phase series EPS that still application waits for mixture load at fan of air conditioning, elevator, rolling door, exhaust, water pump; 3 it is the EPS of frequency conversion series that gives electromotor power supply directly. Of article introduction is the most overall mixture load power supply of three-phase series EPS. Systematic stage amounts to the 2 EPS that are based on a stage to amount to transducer EPS solution basically used transducer to take on the function of drive of inversion communication electric machinery of rolling door of water pump of fan of fire extinguishing system. The stage amounts to EPS guest to make the connection that turns special transducer to be able to come true truly to shed bus bar continuously in all, can apply at EPS industry not only thereby, in the OK also at chemical fibber, glass applying that make a trade. The stage amounts to special transducer and synchronous card form a complete set to use, can realize an input output is phasic and identical, satisfied the application of special situation thereby. Be aimed at the characteristic of drive of EPS industry electric machinery, the stage amounts to transducer to basically increase automatic torsion compensation, torsion to compensate the parameter such as limitation, unusual restart, will satisfy special industry requirement. The EPS that covers suitably with transducer charges the cost that module reduces for the client, reduced heavy transformer, reduced transport costs. 2.

A when the whole of 1EPS special machine summarizes a stage to amount to EPS special machine main characteristic can come true to shed bus bar continuously in all namely, expanded thereby the applied domain of EPS special machine. At the same time in-house contactor and the straight liquefaction of the soft circuit that start satisfied the requirement that the batteries of special machine starts EPS directly. The stage amounts to EPS special transducer to pass collocation proper low filter and a transformer, can form the mixture sex load with very high reliability special inverter. And assure the output voltage stability of inverter and undee and flowing sex. The stage amounts to EPS lash-up power source the application of the majority circumstance that special transducer wants to satisfy EPS industry, it is a of EPS manufacturer first selection special sex transducer. 2.

2 functional characteristic that amount to EPS special machine (1) contactor of the auxiliary power source of transducer, soft circuit that start was to use straight liquefaction, because this can realize power supply of direct direct current completely. (2) exceed strong hardware and software protection function, assured transducer dependability. (3) embedded a variety of modulation means, thereby can applicable a variety of transformer, made sure output carries voltage weaveform to be close to Yu Zhengxian wave more thereby. (4) the stage amounts to EPS special transducer to have AC380V, AC220V two kinds of norms, power limits from 0 - 220KW, can satisfy the requirement of different situation of the client. (5) what the adoption of synchronous card made sure input output is phasic is identical. 2.

3 amount to EPS special transducer to use a design (1) electric principle design. If the graph is shown 1 times,communication sheds principle of EPS of double power supply continuously. Principle of EPS of straight power supply drifting sheet is shown 2 times like the graph. Graph 2 direct current of graph of principle of EPS of double power supply of 1 communication dc are only principle of power supply EPS (2) the definition that controls terminal explains function of terminal grade terminal explains FWD is turning movement - stop to dictate REV inverts run - stop instruction MI1.

4 amount to EPS transducer special parameter parameter designs special parameter specific application cancels PHL to call the police breakdown satisfied mixture load to ask; Single-phase, polyphase. Of frequency of taller carrier wave of carrier wave frequency raise the noise requirement that satisfied a system; Below means leaving a line, <120min of transducer working hours, the need LU that can ask carrier wave frequency achieves highest LU voltage to allow potential energy software to install the wave motion that satisfied batteries voltage calls the police setting of software of voltage reply accurate potential energy satisfied the need with breakdown quick response to output voltage to be in 3V (EPS software function) sky of EPS of national level requirement carries and be fully loaded with a circumstance to fall, output voltage should fluctuate in 5V; Industry standard is in 3V; The time that start can be achieved 0.

0 1S is contented and urgent response demand; The restriction of main point electric current that also is lash-up power source is standard exceed transducer in load when shedding a point too, transducer undertakes frequency voltage limiting is handled falling, assure what electric current does not exceed transducer to spread bit of power too paragraph diversification client is doing the likelihood in the process to need each power paragraph transducer, and the manufacturer of requirement transducer is consistent. Automatic torsion compensation restricts gain of automatic torsion compensation to turn automatically poor compensation gain is OK according to laden state, self-correcting outputs voltage size, make the air gap magnetic field of electric machinery is maintained in rated, in order to get optimal movement state. Unusual activation again frequency (do not include Oc, ocn, ocd, occ, ov, BB is unusual) leave factory set is worth 00 happen when driver unusual (do not include Oc, ocn, ocd, occ, ov, BB is unusual) , and when disappearing unusually automatically, this parameter allows driver automatic revert and with unusual the parameter set before runs. Unusual activation again the frequency is automatic revert time this parameter set is unusual activation again the frequency is automatic revert time, if happen unusual and activation again after the success, at be being done not have in set time any unusual happen, criterion driver is met revert of record of will unusual number is 0. The stage amounts to 3 last words EPS special transducer came true truly the guest is made change a service, develop according to the technical characteristic of EPS industry completely, satisfied the requirement of EPS industry client. The stage amounts to transducer with its firm tone management and higher sexual price are compared got of the user reputably. Vestibule amounts to rigorous quality management, good performance and powerful technology assisted ability to come true truly the guest is made change a service. CNC Milling
