Problems solved by technology

[0002] Most of the existing circuit breakers adopt a mechanical structure to keep the opening state or closing state in a fixed state. Such equipment has a complex structure and is inconvenient to operate.
In addition, the operation of the circuit breaker often requires part of the power as a power source in order to power the equipment to perform related operations. This equipment cannot work normally in the event of a power failure or power failure, or requires an additional power supply, which is very inconvenient.

Embodiment Construction

[0019] Describe in detail below in conjunction with accompanying drawing:

[0020] like figure 1 As shown in , the permanent magnet mechanism circuit breaker includes a permanent magnet control part, a transmission mechanism and a vacuum breaking mechanism. The permanent magnet control part includes a closing coil 4, an opening coil 6, a static iron core 2 and a 4 and the moving iron core 3 and the permanent magnet 5 between the opening coil 6. Firstly, the control current should be turned on, and the first time to turn on the current should wait for 60S. At this time, the energy storage capacitor is fully charged (the red light of the controller stops flashing), and at the same time, the power supply of the undervoltage release is also ready to be connected, and the circuit breaker is in the ready state for operation.

[0021] like figure 2 The block diagram shown is the specific connection method of the control circuit. The DC 220V power is passed to the drive coil throu...

Abstract

The invention provides a breaker with a permanent magnet mechanism. The breaker comprises a permanent magnet control part for controlling on and off of a vacuum breaker mechanism through a transmission mechanism so as to control a main switch; as a permanent magnet (5), a closing coil (4) and an opening coil (6) are matched to use, the breaker can be kept at an on position and an off position; moreover, a hand generator (35) is provided and serves as a power source at power failure; and a capacitor group (32) is used as a power storage device. The breaker can work normally and safely in a power failure state.

Description

(1) Technical field [0001] The invention relates to a permanent magnet mechanism circuit breaker, in particular to a permanent magnet mechanism circuit breaker with a hand generator. (2) Background technology [0002] Most of the existing circuit breakers adopt a mechanical structure to keep the open state or the closed state in a fixed state. Such equipment has a complex structure and is inconvenient to operate. In addition, the operation of the circuit breaker often requires part of the power as a power source to power the equipment to perform related operations. This equipment cannot work normally in the event of a power failure or power failure, or requires an additional power supply, which is very inconvenient. [0003] Here we propose a circuit breaker controlled by a permanent magnet, which has a simple structure and is easy to operate. In addition, it is equipped with a hand generator, which can operate the circuit breaker normally in the event of a power failure or ...
