ENERGY RESERVING CAPACITANCE BRAKE-JUMPING DEVICE FOR TRANSFORMER SUBSTATION

The utility model discloses an energy reserving capacitance brake-jumping device for a transformer substation. The energy reserving capacitance brake-jumping device for a transformer substation is composed of a charging loop, an energy reserving loop, a discharge loop, and a monitoring and checking loop, and is concentratedly installed inside two rectangle box bodies with shifting fork type structures. The energy reserving capacitance brake-jumping device for a transformer substation is used as the protection and brake-jumping power supply of the compact type transformer substation in the voltage grades of 110KV and below 110KV. When the energy reserving capacitance brake-jumping device for a transformer substation normally runs, the energy reserving capacitance brake-jumping device for a transformer substation is carried out floating charge by a three-phase bridge rectifier. When an electric network has faults, the energy stored by the energy reserving capacitance brake-jumping device for a transformer substation supplies to protect action and the brake-jumping of a breaker. The utility model solves various problems existing in the existing mode. Compared with other direct current power supply modes, the utility model has the advantages of less investment, long service life, small size, simple and convenient running, low maintenance charge, etc.
