Embodiment 1

[0017] see figure 1 , a small high-breaking hydraulic or pneumatic circuit breaker, including a housing 2, a contact operating mechanism 5, a hydraulic or pneumatic electromagnetic coil 9 are arranged in the high-breaking hydraulic or pneumatic circuit breaker housing 2, (in the hydraulic electromagnetic coil There are oil cup or gas cup and moving iron core), armature, the armature is sucked and pulled end 7, moving contact pulling part 4, magnetic guide sheet 8. Compared with the prior art, first adjust the gap between the armature pushing end 12 and the lock shaft 11 to be about 0.5 millimeters, 1, the movable contact puller 4 is set on the movable contact, the so-called movable contact puller 4 It is a part set at one end of the armature, which can help the moving contact to break. The moving contact pulling part 4 can be pulled by the armature pulling end 10 when short-circuited, and the moving contact pulling part 4 is then pulled to break the moving contact. Spring 13...

Embodiment 2

[0019] see figure 2 ,Will figure 1 Part of the terminal post is removed, and the arc extinguishing cover is reduced to make a smaller volume and high breaking hydraulic or pneumatic circuit breaker.

Abstract

The invention discloses a small-sized high-breaking hydraulic or pneumatic circuit breaker, and solves the technical problem that the breaking capacity of the small-sized hydraulic or air-pressure circuit breaker in the current market is further improved. According to the small-sized high-breaking hydraulic or pneumatic circuit breaker, a contact operating mechanism, a hydraulic or pneumatic electromagnetic trip coil, an armature and a moving contact pull piece are arranged in a shell of the high-breaking hydraulic or pneumatic circuit breaker, the moving contact pull piece is a part arranged at one end of the armature, the part can help a moving contact to break, and a magnetic conductive sheet can be connected through a rivet and a gasket. The magnetic conductive sheet, the magnetic conductive sheet spring and the rivet on the attracted and pulled end of the armature are omitted, the attraction and pulling force in a hydraulic or pneumatic electromagnetic coil and the spring force in the oil cup and the gas cup are increased, and the same effect can be achieved. Compared with the prior art, the moving contact pull piece is arranged on the moving contact, the magnetic conductive sheet is arranged on the armature, the breaking capacity of the hydraulic or air pressure circuit breaker is improved, and through the improvement, the hydraulic or air pressure circuit breaker is more reliable and applicable, and the breaking capacity is greatly improved.

Description

technical field [0001] The invention relates to the technical field of high-breaking hydraulic circuit breakers, in particular to a small high-breaking hydraulic or pneumatic circuit breaker. Background technique [0002] The breaking capacity of small hydraulic circuit breakers on the market is low, and the application range is small. Contents of the invention [0003] The purpose of the present invention is to provide a small high-breaking hydraulic or pneumatic circuit breaker to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A small high-breaking hydraulic or pneumatic circuit breaker, including a housing, a contact operating mechanism, a hydraulic or pneumatic electromagnetic coil, (an oil cup is provided in the hydraulic or pneumatic electromagnetic coil) Or air cup and moving iron core), armature, armature is sucked and pulled e...
