Device for monitoring state of multi-path switch

Abstract

The invention provides a device for monitoring a state of a multi-path switch. The device comprises a shell, wherein the shell is in a rectangular shape with two sides beveled, a plurality of two-position input wiring seats and a plurality of two-position output wiring seats are respectively arranged on bevel surfaces of the shell, a plurality of button switches are arranged at the middle part of an upper surface of the shell, one button switch is arranged only near to one input wiring seat or one output wiring seat, and a circuit board is arranged in the shell, is used for monitoring a switch state and comprises multiple groups of switch connection input ends, a multi-path voltage detection module, a voltage conversion module, the plurality of button switches, a combined logic circuit unit and a power supply module. By the device, the state of the multi-path switch is monitored, a warning signal is output during automatic striping or power shortage of an input end of the monitored switch, and centralized management is facilitated.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a device for monitoring the state of a multi-way switch. Background technique [0002] At present, many low-voltage power switches such as circuit breakers need button switches during use, and circuit breakers usually have short-circuit protection functions, because some electrical loads do not have the nature of being easy to observe when power is off, such as lights or display screens, and in When using it, it is difficult to find out whether it is powered off because it does not need people to watch it all the time. When the superior monitoring center finds that the circuit breaker is disconnected, it is difficult to judge in time whether it is manually closed due to maintenance needs or the automatic short circuit protection of the circuit breaker. When multiple switches are used, it is more difficult to monitor the state of each switch, so it is necessary to design a device...

[0002] At present, many low-voltage power switches such as circuit breakers need button switches during use, and circuit breakers usually have short-circuit protection functions, because some electrical loads do not have the nature of being easy to observe when power is off, such as lights or display screens, and in When using it, it is difficult to find out whether it is powered off because it does not need people to watch it all the time. When the superior monitoring center finds that the circuit breaker is disconnected, it is difficult to judge in time whether it is manually closed due to maintenance needs or the automatic short circuit protection of the circuit breaker. It is more difficult to monitor the state of each switch when there are multiple switches, so it is necessary to design a device for monitoring the state of multiple switches
