Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a circuit breaker with an alarm to solve the problem that the existing technology cannot quickly start the alarm device when the circuit breaker is reset and the alarm is often directly controlled through the circuit. It is prone to abnormal wiring that leads to alarm failure, resulting in the failure to know the abnormality of the circuit breaker in time

Embodiment

[0023] see Figure 1-Figure 4, the invention provides a circuit breaker with an alarm: its structure includes an upper terminal 1, an inlet hole 2, a fixing hole 3, a manual trip button 4, a main body 5, a reset button 6, an operating handle 7, a lower wiring Terminal 8, mounting block 9, alarm device 10, the alarm device 10 is installed on the right side of the main body 5 by buckling, the top of the main body 5 is provided with an upper terminal 1 and an integrated structure, the manual The trip button 4 is installed on the upper end of the main body 5 by embedding. The middle part of the main body 5 is provided with a rectangular concave hole for installing the reset button 6. There are four fixing holes 3 and they are distributed in pairs on the upper terminal 1. With the front end on the left side of the lower terminal 8, four inlet holes 2 are provided in total and are arranged on the left side of the upper terminal 1 and the lower terminal 8 through a penetrating method...

Abstract

The invention discloses a disconnector with an alarm. The structure of the disconnector with the alarm includes an upper wiring end, wire inlet holes, fixing holes, a manual trip button, a main body,a restoration button, an operation handle, a lower wiring end, a mounting block and the alarm. The alarm is mounted on the right side of the main body in a clamped mode, the top of the main body is provided with the upper wiring end, and the upper wiring end and the main body are of an integrally-formed structure. The disconnector with the alarm has the advantages that according to stress generated when a disconnection trip block presses down during disconnection, the alarm drives a triggering pick to trigger a transmission device and then drives a transmission plate to power on a conductive contact part and a conductive piece, therefore, the alarm is started when an alarm main unit acquires electric energy, then, the transmission plate and the transmission device can automatically restorethrough first and second springs, the function of automatically releasing alerts is achieved, and the situation is effectively avoided that because a circuit is powered on for a long term, conduciveabnormity occurs; it is convenient for workers to know alarm positions in time.

Description

technical field [0001] The invention is a circuit breaker with an alarm, which belongs to the field of circuit breakers. Background technique [0002] Power distribution is an extremely important link in the generation, transmission and use of electricity. The power distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit breaker is an electrical appliance with a large amount of use. [0003] Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. Combination with overheating and underheating relays, etc. Moreover, there is generally no need to change parts after breaking the fault current. At present, it has been widely used. [0004] A circuit breaker is a device used to c...
