Real-time humidity monitoring and alarming device for terminal box

Abstract

The invention discloses a real-time humidity monitoring and alarming device for a terminal box. The real-time humidity monitoring and alarming device comprises at least one sensor capable of sensing an external humidity value, an analog-to-digital conversion module connected with the sensor, a control system connected with the analog-to-digital conversion module, a display module connected with the control system, a display connected to the display module, and a wireless transmission module connected to the control system. The real-time humidity monitoring and alarming device uses the humiditysensor to monitor the humidity inside the terminal box in real time and connect the humidity sensor with a host computer through a wireless network. A worker can know the humidity value in the terminal box in a machine room. When the humidity increases, the real-time humidity monitoring and alarming device can promptly send an abnormal signal to the host computer in order to ask a maintainer to perform inspection and maintenance, thereby shortening a maintenance interval and improving efficiency.

Description

technical field [0001] The invention relates to the field of terminal box monitoring, in particular to a real-time humidity monitoring and alarm device for a terminal box. Background technique [0002] Terminal block is an accessory product used to realize electrical connection, which is industrially divided into the category of connectors. With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. [0003] The terminal box is a kind of interface device for switching construction lines, marking branch lines, and providing convenience for wiring and checking lines. In some cases, in order to facilitate construction and debugging, some more special products with more regular installation settings, such as short-circuit isolators, can be inst...

Problems solved by technology

[0004] Due to long-term wind and rain, the sealing performance of some outdoor terminal boxes and mechanism boxes in substations has deteriorated, resulting in the intrusion of a large amount of water vapor from the outside; If exposed, the insulation strength of the devices in the terminal box will be reduced, resulting in a short circuit of the secondary terminal block, and tripping of the small air switch, which will cause the relay protection device to refuse to operate, cause equipment failure or cause switch malfunction, and bring serious damage to the actual operation of the power station.
