Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The embodiment 1 of the invention discloses a circuit breaker tripping alarm device. As shown in fig. 1, the breaker QF is connected to the line for controlling the on/off of the line. It should be understood that the wiring described in embodiments of the present invention generally includes live, neutral and ground wires. Specifically, when the controlled line fails, the circuit breaker QF will trip automatically to cut off the power supply. The circuit breaker may be a low voltage circuit breaker.
The circuit breaker tripping alarm device of the embodiment of the invention comprises: switch board and the alarm unit who sets up in the switch board. The switch board is the conventional equipment that can set up usually in the existing circuit, and no longer repeated here. The alarm unit includes: an intermediate relay, an audible and visual alarm A and a travel switch SQ.
Two ends of a control coil ZJ1 of the intermediate relay are respectively connected with a live wire and a zero wire of a line. The normally closed contact ZJ2 of the intermediate relay is connected in series between the live wire of the line and the audible and visual alarm A. When the breaker QF is opened, the normally closed contact ZJ2 of the intermediate relay is opened. The audible and visual alarm A is also connected with a contact of a travel switch SQ. The audible and visual alarm A can adopt a commercial audible and visual alarm, and generally comprises a buzzer and an alarm lamp. The audible and visual alarm A of the embodiment of the invention alarms when the normally closed contact ZJ2 of the intermediate relay is opened, and does not alarm when the normally closed contact ZJ2 of the intermediate relay is closed. The other contact of the travel switch SQ is electrically connected with an electric control board in the power distribution cabinet. Any one of two contacts of the travel switch SQ is arranged on a cabinet door of the power distribution cabinet, and the rest contact is arranged on a door frame of the power distribution cabinet. The two contacts are positioned so that they are contactable. Therefore, when the cabinet door is closed, two contacts of the stroke switch SQ are contacted, the stroke switch SQ is closed, and the alarm unit is connected into the circuit and is in a running state. When the cabinet door is opened, two contacts of the travel switch SQ are disconnected, the travel switch SQ is disconnected, the alarm unit is disconnected, and the cabinet door is in a running stop state.
The working principle of the circuit breaker tripping alarm device is as follows:
and the cabinet door of the power distribution cabinet is closed, the travel switch SQ is normally closed, and the whole alarm unit is connected into the circuit and is in an operating state. When the circuit where the breaker QF is located normally works and no fault occurs, the breaker QF does not work, the control coil ZJ1 of the intermediate relay is electrified, the normally closed contact ZJ2 of the intermediate relay is normally closed, and the audible and visual alarm A does not give an alarm. When a circuit where the breaker QF is located breaks down, the breaker QF acts to be disconnected, the control coil ZJ1 of the intermediate relay loses power, the normally closed contact ZJ2 of the intermediate relay is disconnected, the audible and visual alarm A gives an alarm, flashing and alarming sound are generated, the worker is prompted to break the circuit of the breaker QF, and therefore the worker can conveniently conduct corresponding overhaul.
When the staff opens the cabinet door of switch board and overhauls, travel switch SQ disconnection, alarm unit disconnection from the circuit is in the stall state, can not report to the police, avoids producing the interference. When the staff finishes overhauling and closes the cabinet door of the power distribution cabinet, the travel switch SQ is normally closed, the whole alarm unit is connected into the circuit again and is in an operating state, and the monitoring of the action of the breaker QF is recovered.
Example 2
In embodiment 2 of the present invention, when there are multiple lines, each line is provided with one breaker, and the number of the intermediate relays is equal to the number of the breakers. Two ends of a control coil of each intermediate relay are respectively connected with a live wire and a zero wire of each circuit, and a normally closed contact of each intermediate relay is connected in series between the live wire and the audible and visual alarm of each circuit. Other circuit structures are the same as embodiment 1, and are not described herein again.
Fig. 2 shows a schematic circuit diagram when the number of lines is two. For the first line, the breaker QF1 is connected with the first line and controls the on-off of the first line. Two ends of a control coil ZJ11 of the intermediate relay are respectively connected with a live wire and a zero wire of the first circuit. The normally closed contact ZJ12 of the intermediate relay is connected in series between the live wire of the first line and the audible and visual alarm A. For the second line, the breaker QF2 is connected with the second line and controls the on-off of the second line. Two ends of a control coil ZJ21 of the intermediate relay are respectively connected with a live wire and a zero wire of the second line. The normally closed contact ZJ22 of the intermediate relay is connected in series between the live wire of the second line and the audible and visual alarm A. Therefore, when the first line fails and the breaker QF1 is opened, the audible and visual alarm a can give out a corresponding alarm. When the second line has a fault and the breaker QF2 is disconnected, the audible and visual alarm A can also send out a corresponding alarm. For example, the audible and visual alarm a includes a plurality of alarm lamps. And the normally closed contact of each intermediate relay is connected with each connecting terminal of the audible and visual alarm A. Each connection terminal connects each alarm lamp to when making different circuit faults, the different alarm lamps of scintillation, the circuit of the staff of being convenient for discernment trouble. The working principle of embodiment 2 is the same as that of embodiment 1, and the description thereof is omitted.
In summary, the circuit breaker trip alarm device of 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, the working personnel can timely handle the fault and recover power supply.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
