Explosion-proof electric chain hoist voltage transformer works like?

 Below we explain three points:
1, tap: to fit the needs of the power grid, the general has tapped transformer high side, can not fully guarantee tap sync switch, load tap so can not run in parallel.
  2, explosion-proof small electric hoist voltage transformer: primary winding turns N1, less secondary winding turns N2, the equivalent of a step-down transformer. PT at work in the primary winding and a secondary winding is connected in parallel, respectively, in the primary circuit and the secondary coil voltage control loop. So if the secondary winding shorted, will result in a very large secondary current.
3, Used / drawer: Handcart and drawers are part of the high voltage switchgear and low voltage switchgear, high voltage circuit breakers are installed and low voltage circuit breakers and relays and other components. They fixed switchgear function is basically the same, the main difference is to facilitate the proof electric hoist maintenance and repair.
Explosion-proof electric chain block can be installed separately using the word overhead beam, explosion-proof electric chain hoist can be installed on supporting electric or manual single-beam, dual-beam, cantilever, gantry cranes. Electric chain hoist, light weight, high level. Explosion-proof chain hoist better safety performance, high reliability, and low failure rate. Working low noise, overload the power, the braking force is superior.
