Pole-mounted circuit breaker power taking device, circuit breaker mounting structure and power taking method

Abstract

The invention provides a pole-mounted circuit breaker power taking device, a circuit breaker mounting structure and a power taking method. The pole-mounted circuit breaker power taking device comprises a circuit breaker body, a feeder terminal electrically connected to the circuit breaker body and used for controlling opening and closing of the circuit breaker body, a main power supply module that comprises a current transformer that is electrically connected with the feeder terminal and converts the high voltage into a working voltage required by the feeder terminal and transmits the working voltage to the feeder terminal, a standby power supply module, and a transformer chamber; the standby power supply module comprises an energy storage unit and a transformer chamber electrically connected with the energy storage unit, the energy storage unit is arranged on the circuit breaker body and used for storing electric energy, and the transformer chamber is electrically connected with the feeder terminal; and the transformer chamber is used for converting the high voltage obtained by the energy storage unit into a working voltage required by the work of the feeder terminal and transmitting the working voltage to the feeder terminal. The pole-mounted circuit breaker power taking device and the pole-mounted circuit breaker power taking method provided by the embodiment of the invention can improve the reliability and the safety of the pole-mounted circuit breaker.

Description

technical field [0001] Embodiments of the present invention generally relate to the circuit breaker field, and more specifically, relate to a pole-mounted circuit breaker power taking device, a circuit breaker installation structure and a power taking method. Background technique [0002] With the continuous development of smart grids, people's requirements for intelligent electrical equipment are also increasing, and the boundaries between primary and secondary equipment will become increasingly blurred. In this regard, the State Grid Corporation is vigorously promoting the integration of primary and secondary electrical equipment. Trying to break the existing pattern of electrical equipment.

Problems solved by technology

[0003] The traditional pole-mounted circuit breaker is composed of three parts: the circuit breaker body, the feeder terminal and the voltage sensor. The composition is cumbersome, there are many leads, and the installation is complicated. The terminal will lose power, and the voltage transformer can only be removed and replaced. The workload is heavy, and the power must be cut off for a long time, which reduces the reliability of power supply and may even cause serious economic losses.
