Abstract

The invention discloses a high-voltage vacuum breaker with contact temperature measurement function and a temperature measurement method thereof, and is characterized in that the primary main contact of the high-voltage vacuum breaker is provided with a temperature measurement device connected with a controlling device through an optical fiber transmission line; the primary contact temperature measurement signal of the breaker sent by the temperature measurement device is compared with data set in the controlling device to timely display and send over temperature alarming; and a breaker-breaking signal is sent when necessary. The structure and the method have following advantages that: 1, the equipotential technique is applied to high-voltage environment, a general temperature measurement sensor is used so that the product cost is controlled within several hundred yuan, and the seamless joint with the breaker is finished in a factory, which is convenient for commercialization, popularization and application; 2, the temperature measurement data is transmitted through optical fibers and is electrically insulated and isolated in high-voltage environment, thereby timely monitoring the temperature of the primary contact of the breaker and effectively preventing the contact from being burned due to overheat; 3, the temperature measurement technique is used to conventional products, thereby improving the technical content of products and increasing market competitiveness.

Description

technical field [0001] The invention relates to a high-voltage switch device in a power system, in particular to a high-voltage vacuum circuit breaker with a contact temperature measurement function and a temperature measurement method thereof. Background technique [0002] The vacuum circuit breaker is the main electrical equipment for breaking the high-voltage power circuit. Whether the dynamic and static contacts are in good contact is the main link to ensure the reliable operation of the equipment. According to statistics, a large part of the accidents of the vacuum circuit breaker are due to the loose connection of the dynamic and static contacts. Or poor contact caused by overheating and ablation of the joint. The ablation of the contact has a time course, and it does not happen immediately. Before the accident, there will always be a sign of overheating. The more serious the heat accumulation is, it will eventually cause an accident. On-line detection of the temperat...
