Circuit breaker automatic monitoring device

Abstract

The invention discloses an automatic breaker monitoring device. The monitoring device comprises a detector host, the upper part of the detector host is provided with a data line, one end of the data line is provided with a probe, a conical cover body is arranged in the periphery of the probe, a wear-resistant composite layer made of a high-intensity multilayer composite material wraps the cover body, the minor-diameter end of the cover body is connected with the probe, the major-diameter end of the cover body is provided with an elastic seal ring, the elastic seal ring is a conical seal ring formed by a plurality of trapezoidal rubber sheets, the narrow end of each rubber sheet is connected with the cover body, and every two adjacent rubber sheets are partially overlapped. Thus, the device can monitor a sulfur hexafluoride breaker automatically, the cover body is installed outside the probe of a present detector, the wear-resistant composite layer made of the high-intensity multiplayer composite layer wraps the cover body, the intensity of the cover body is improved greatly, the heat insulation effect is high, and influence of wind power and temperature during probe monitoring is improved.

Description

technical field [0001] The invention relates to an air leakage monitoring system, in particular to an automatic monitoring device for a circuit breaker. Background technique [0002] Sulfur hexafluoride circuit breaker is a circuit breaker that uses sulfur hexafluoride SF6 gas as the arc extinguishing medium and insulating medium. From the structure, the sulfur hexafluoride circuit breaker can be divided into two types, one is the porcelain column type, The other is the tank type. At present, in the power transmission operation of substations, the detection of SF6 gas leakage of power supply equipment has problems of low accuracy and large errors. The main reason is that the detection is usually carried out in an open environment. In the case of flow influence, and in the case of small air leakage at the leak point, it is difficult to detect the leak point, resulting in missed detection, resulting in the inability of the sulfur hexafluoride circuit breaker to function and c...

Problems solved by technology

At present, in the power transmission operation of substations, the detection of SF6 gas leakage of power supply equipment has problems of low accuracy and large errors. The main reason is that the detection is usually carried out in an open environment. Under the influence of flow, and when the air leakage of the leak point is small, it is difficult to detect the leak point, resulting in missed detection, resulting in the inability of the sulfur hexafluoride circuit breaker to function, resulting in safety hazards

In addition, the existing enclosure device for detecting leaks is easily affected by changes in the external temperature environment, which reduces the accuracy of monitoring; in the case of unstable installation, it is easy to fall and damage, the strength is poor, and the anti-wear performance is insufficient
