Description

Technical Field

[0001] The utility model relates to the field of state monitoring, in particular to a trip alarm device for a connection part of a switch or knife switch transmission mechanism. Background Art

[0002] The transmission mechanism is an important component of switches and knife switches, and contains one or more connection parts connected to other devices. During the movement, the connection parts are subjected to greater force, and the problem of tripping often occurs. In the prior art, there is a lack of effective monitoring of the tripping of the connection parts of the transmission mechanism, which usually relies on on-site inspection by personnel. However, the transmission mechanism is generally set in a protective shell, which is difficult to observe directly, resulting in the tripping problem cannot be discovered in time. Utility Model Content

[0003] The utility model aims to provide a trip alarm device for the connection part of the transmission mechanism of a switch or knife switch, which is used to solve the problem that the existing transmission mechanism is arranged in a protective shell and is difficult to directly observe, resulting in the trip problem cannot be discovered in time.

[0004] In order to solve the above problems, the technical solution of the utility model is:

[0005] A trip alarm device for the connection part of a switch or knife switch transmission mechanism comprises a shell, a power supply is arranged in the shell, the power supply is connected with a control unit, a display unit, a signal relay and an audible and visual alarm unit, the control unit is connected with the display unit and the audible and visual alarm unit, the power supply is connected with the signal relay via at least two connecting wires, and the connecting wires are connected via joints.

[0006] The connector includes a plug and a socket.

[0007] The beneficial effects of the utility model are as follows: the device can effectively monitor whether the connection parts of the switch and knife switch transmission mechanism are working normally. If a tripping failure occurs during the movement of the connection part, the monitoring system can be used to quickly discover and determine the faulty mechanism at a distance, thereby improving the accuracy and timeliness of fault judgment.

[0016] like Figures 1 to 3 As shown, a tripping alarm device for the connection part of a switch or knife switch transmission mechanism comprises a shell 2, a power supply is arranged in the shell 2, the power supply is connected to a control unit, a display unit 4, a signal relay and an audible and visual alarm unit 5, the control unit is connected to the display unit 4 and the audible and visual alarm unit 5, the power supply is connected to the signal relay via at least two connecting wires, the connecting wires are connected via connectors, and two conductors are arranged in each connecting wire.

[0017] The connector includes a plug 8 and a socket 7. Since two wires are provided in the connecting wire, when multiple connecting wires 6 are connected in sequence, the last wire is in a disconnected state, so the terminal 9 is required to connect the two wires at one end of the connecting wire to form a path between the power supply and the signal relay.

[0018] Figure 2 Middle: Connect the two wires in the connecting line to the power terminal 1 and the relay terminal 3 respectively. When the external connecting line 6 normally powers the relay in the signal relay, the signal device in the signal relay does not send a signal to the control unit and there is no alarm.

[0019] Figure 3 Middle: After the external connection line is tripped and causes the relay in the signal relay to lose power and change position, the signal device in the signal relay sends a signal to the control unit, and the control unit controls the display unit 4 and the sound and light alarm unit 5 to operate, and the device alarms.

[0020] When the utility model is implemented:

[0021] 1. If Figure 4 As shown, two connecting wires are fixed to the two ends of the connecting part of the transmission mechanism to be monitored. When the connecting part operates normally, the power supply supplies power to the signal relay through the connecting wire 6. When the connecting part is tripped, Figure 6 As shown, the plug 8 and socket 7 between the two connections are also disconnected, the circuit is interrupted, the signal relay loses power, and the device Place The main body can issue an alarm prompt.

[0022] 2. If Figure 5As shown, when the transmission mechanism needs to be monitored, multiple connecting lines are fixed to multiple transmission mechanisms 10, and the connectors are located between two adjacent transmission mechanisms 10. When any connection part of the transmission mechanism 10 is disconnected, the circuit will be disconnected and an alarm will be issued, which is convenient for monitoring multiple connection parts of the same transmission mechanism or multiple connection parts in the same space.

[0023] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be deemed to be limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
