Embodiment 1

[0042] like figure 1 As shown, an intelligent knife switch system includes an isolating knife switch 1, a heat-sensitive element 2 and a monitoring device; the isolating knife switch 1 includes a static contact 3 and a moving contact 4; the static contact 3 is provided with an inner contact finger 5 , the thermosensitive element 2 is arranged between the static contact 3 and the inner contact finger 5; the monitoring device is arranged on the static contact 3; the monitoring device includes a power supply 6, a single-chip microcomputer module, a temperature sensor and a wireless module; the power supply 6 is connected with the single-chip microcomputer module respectively 1. The temperature sensor is electrically connected to the wireless module, and the single-chip microcomputer module is electrically connected to the temperature sensor and the wireless module respectively; the temperature sensor is in contact with the thermal element 2 .

[0043] The isolating knife switch 1...

Embodiment 2

[0047] like figure 2 , image 3 and Figure 4 As shown, this embodiment relates to an intelligent knife switch system, and its structure is roughly the same as that of Embodiment 1. This embodiment is further optimized on the basis of Embodiment 1. The single-chip microcomputer module is electrically connected to a GPS module, and the GPS module and the wireless module electrical connection.

[0048] The isolation switch 1 is generally installed in the electric field, and there are a large number of isolation switches 1 in the electric field, so in order to facilitate the timely monitoring of the isolation switch 1 and the implementation of emergency measures, the single-chip microcomputer module is electrically connected to the GPS module, and the GPS module and the wireless module Electrical connection, through the setting of the GPS module, the position of the overheated isolation switch 1 can be accurately judged, which is convenient for the staff to find the correspond...

Abstract

The invention discloses an intelligent disconnecting link system which comprises an isolation disconnecting link, a thermosensitive element and a monitoring device. The isolation switch comprises a static contact and a moving contact. The static contact is provided with an inner contact finger, and the thermosensitive element is arranged between the static contact and the inner contact finger; the monitoring device is arranged on the static contact; and the monitoring device comprises a power supply, a single-chip microcomputer module, a temperature sensor and a wireless module. The power supply is electrically connected with the single-chip microcomputer module, the temperature sensor and the wireless module. The single-chip microcomputer module is electrically connected with the temperature sensor and the wireless module. The temperature sensor abuts against the thermosensitive element. Through the mutual cooperation of the thermosensitive element and the monitoring device, the temperature can be monitored in real time while the problem that the interface of the disconnecting link is overheated is solved, and the problems that the clamping force of the interface of the disconnecting link is reduced, so that overheating is caused, and negative effects on safety production, economic benefits and social benefits are brought are effectively solved.

Description

technical field [0001] The invention belongs to the field of electric safety equipment, in particular to an intelligent knife switch system. Background technique [0002] Isolation switch is the most widely used electrical appliance in high-voltage switchgear. Its working principle and structure are relatively simple, but due to the large amount of use and high reliability requirements, it is very important for the design, establishment and safe operation of substations and power plants. have a greater impact. [0003] At present, in the power system, the inspection of the isolation knife switch is still a regular inspection inspection and temperature measurement, and there are no technical measures to realize uninterrupted monitoring around the clock. May develop into an electrical accident. [0004] Moreover, with the use of the isolation knife switch, due to the repeated opening and closing of the static contact and the moving contact, the clamping force of the static c...
