electric motor stator rotor lamination motor parts Specifications
1. Lamination of electric motor
2. IP54 class F
3. 100% copper
4. silicon steel stamping
5.stunning performance
Manufacturer of the product technical parameters are given in dynamic stability multiples Kes and thermal stability of multiple Kt, so according to the following formula check dynamic stability and thermal degrees respectively. 1) dynamic stability check of Kes x I1N acuity iSh and 2) thermal stability check (KtI1n) 2 t p I (3) up tima type, t for the thermal stability of the current time. 1) wiring shall comply with the series of current transformer principle: namely a winding shall be measured circuit in series, and while the secondary winding with all instrument load series; 2) according to the measured current size, select the appropriate change, otherwise the error will increase. At the same time, secondary side must be grounded at one end, in case once insulation damage, a side high pressure into the second low voltage side, personal and ac motor prices equipment accident; 3) secondary side is absolutely not allowed to open, because once the open circuit, the primary side current I1 all become the magnetizing current, causing phi m and E2 in, cause excessive iron core saturation magnetization, serious fever and burning coil; At the same time, the excessive saturation magnetization, magnetic circuit make error increases. In addition, two ANP gost motor side open-circuit make E2 reaches hundred volts, once touched cause accident getting an electric shock. Therefore, the current transformer secondary side is equipped with short circuit switch, prevent side open at a time.
Specifications
1. effiency: IE2 and IE1
2. 20 years manufacturing experience
3. 12 months guarantee
4. low noise and vibtration
As shown in figure l K0, in use process, once a secondary side open circuit must be removed immediately circuit load, then, to stop processing. Handle all the rear can be used again. 4) in order to meet the measuring instrument, relay protection, acmotortrading.blogspot.com circuit breaker failure judgment and fault wave record device, the generator, transformer, wire, bus section circuit breaker, bus coupler circuit breaker and the bypass circuit breaker loop are set with 2 ~ 8 secondary winding of current transformer. For large current grounding system, generally by the three-phase configuration; For small current grounding system, in accordance with the specific requirements according to the two phase or three phase configuration; 5) for the protection of press with current transformer installed location should be as far as possible eliminate protection device of the Lord is not reserve to set. For example, if there are two sets of current transformers, and location allowed, should the circuit breaker, on both sides make the circuit breaker is in the scope of protection of the cross; 6) in order to prevent the pillar type current transformer bushing flashover caused by bus fault, current transformer is usually arranged in line or transformer side of the circuit breaker; 7) damage, in order to reduce the generator internal fault is used to automatically adjust the excitation device of current transformer should be arranged in the outlet of the generator stator winding side. In order to facilitate analysis and found that internal fault before generator into the system, used for measuring current transformer should be mounted on the generator neutral point.
