Technical Field

The invention relates to the technical field of circuit breakers, in particular to a circuit breaker tripping alarm device.

Background

The protection feature of the existing low-voltage circuit breaker is that when the controlled line breaks down, the low-voltage circuit breaker will trip automatically to cut off the power supply, thus protecting the safety of human body and equipment. However, with the development of society and economy, the requirement of people on the reliability of power supply is increasingly enhanced, and in some occasions, once power failure occurs, accidents or major economic losses and adverse social effects can be caused. Therefore, when a line fails, a trip point needs to be found in time so as to remove the fault point and recover power supply in time.

Disclosure of Invention

The embodiment of the invention provides a circuit breaker tripping alarm device, which aims to solve the problem that a tripping place is difficult to find in time when a line fails in the prior art.

The technical scheme of the embodiment of the invention is as follows:

a circuit breaker trip alarm device, the circuit breaker being connected to a line for controlling the make and break of the line, the circuit breaker trip alarm device comprising: switch board, circuit breaker trip alarm device still includes: set up alarm unit in the switch board, alarm unit includes: an intermediate relay, an audible and visual alarm and a travel switch; the both ends of auxiliary relay's control coil respectively with the live wire and the zero line of circuit are connected, auxiliary relay's normally closed contact concatenates the live wire of circuit with between the audible-visual annunciator, audible-visual annunciator still with travel switch's a contact is connected, travel switch's another contact with automatically controlled board electricity in the switch board is connected, arbitrary one contact setting in two contacts of travel switch is in on the cabinet door of switch board, a remaining contact setting is in on the door frame of switch board, the position of two contacts corresponds.

Further: when the circuit breaker is opened, the normally closed contact of the intermediate relay is opened.

Further: when the cabinet door is closed, two contacts of the travel switch are contacted; when the cabinet door is opened, the two contacts of the travel switch are disconnected.

Further: when the circuit has many, each the circuit sets up one the circuit breaker, the quantity of auxiliary relay with the quantity of circuit breaker equals, each the both ends of auxiliary relay's control coil respectively with each the live wire and the zero line of circuit are connected, each auxiliary relay's normally closed contact concatenates each the live wire of circuit with between the audible-visual annunciator.

Further: audible-visual annunciator includes a plurality of alarm lamps, each auxiliary relay's normally closed contact is connected audible-visual annunciator's each connecting terminal, each connecting terminal connects each the alarm lamp.

The circuit breaker tripping alarm device provided by the embodiment of the invention can control the audible and visual alarm to give an alarm through the intermediate relay so as to determine the tripped circuit breaker, so that a user can conveniently identify power failure caused by tripping and report and repair the power failure, and thus, a worker can timely handle a fault and recover power supply.
