Description

Novel universal circuit breaker

Technical Field

The utility model relates to a circuit breaker technical field specifically is a novel universal circuit breaker.

Background

The universal circuit breaker is also called frame type circuit breaker, and is a mechanical switch electric appliance which can connect, bear and break the current under the normal circuit condition, and can also connect, bear and break the current for a certain time under the specified abnormal circuit condition. Conventional circuit breakers are used to distribute electrical energy and to protect lines and power equipment from overloads, undervoltages, short circuits, etc.

Such circuit breakers typically have a steel frame with all the components mounted within the frame. The high-capacity high-voltage switch has large capacity, can be provided with a release with multiple functions and a plurality of auxiliary contacts, has high sectioning capability and thermal stability, and is commonly used in places requiring high breaking capability and selective protection.

The interface and the switch of the universal circuit breaker are arranged on the panel, the interface is easy to deposit dust to cause poor contact, and the switch is easy to touch to cause line faults.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to solve the problem, the utility model provides a novel universal circuit breaker.

The utility model provides a novel universal circuit breaker, which comprises side plates arranged at two sides of a panel and a cover plate covering the panel, wherein the side plates are provided with first clamping grooves which are vertically arranged, the groove walls of the first clamping grooves are provided with second clamping grooves, and the second clamping grooves are positioned at the upper parts of the side plates; an elastic piece is arranged at the upper end of the second clamping groove;

the cover plate is provided with a plurality of clamping columns for clamping the first clamping grooves, and the clamping column at the lowest end is also used for clamping the second clamping grooves.

The cover plate is used for protecting the panel of the universal circuit breaker, so that not only can the dust accumulation of the interface be prevented, but also the switch can be prevented from being touched and touched by mistake; the installation of apron is realized through the first draw-in groove of card post joint, removes opening or closing that realizes the apron through the card post in first draw-in groove, through the card post joint second draw-in groove of apron lowermost end to compress tightly through the elastic component and realize that the apron is opened the after-fixing, simple structure, convenient operation.

Furthermore, the lower end of the second clamping groove is provided with an inclined plane. Due to the arrangement of the inclined plane, the cover plate can automatically slide and be closed under the action of equipment vibration, and the problem that the cover plate fails due to forgetting to close the cover plate by a worker is avoided.

Furthermore, the elastic part comprises a spring and a steel ball which are connected with each other, and a bayonet used for clamping the steel ball is arranged at the upper end of the clamping column at the lowermost end of the cover plate. The clamping column is pressed through the steel ball clamping bayonet, and the structure is simple.
