Abstract

The invention provides a breaker independent photovoltaic system control power supply, and belongs to the breaker technical field; the breaker independent photovoltaic system control power supply comprises a solar cell panel, a storage battery, a controller, an inverter and a breaker control system; the solar cell panel output end is connected with the first input end of the controller; the storage battery output end is connected with the second input end of the controller; the storage battery input end is connected with the first output end of the controller; the controller second output end is connected with the input end of the inverter; the inverter output end is connected with the power input end of the breaker control system. The breaker independent photovoltaic system control power supply uses a photovoltaic system to replace a conventional PT power supply, provides control power for the breaker, finishes opening/closing motions of the breaker, reduces primary equipment, separates a secondary power supply from the primary system, reduces fault points, and conveniently repairs a secondary power supply protector; the breaker independent photovoltaic system control power supply is simple in operation and maintenance, and stable and reliable in operations.

Description

technical field [0001] The invention belongs to the technical field of circuit breakers, and more specifically relates to a circuit breaker independent photovoltaic system control power supply. Background technique [0002] In the electric power industry, the traditional 10kV line circuit breaker control power supply uses PT power supply, and the PT power supply converts 10kV AC power into 220V AC power through a voltage transformer, and provides it to the circuit breaker as a control power supply, so that the circuit breaker can complete the opening and closing action. However, the traditional PT power supply is easily damaged, has many faults and causes insufficient power supply, which is not convenient for the maintenance of the secondary power supply protection device. Contents of the invention [0003] The purpose of the present invention is to provide a circuit breaker independent photovoltaic system control power supply to solve the technical problems in the prior a...
