A pressure controllable detection device for testing sf6 inflatable cabinets

Abstract

The invention, which belongs to the technical field of SF6 gas-insulated switchboard auxiliary test equipment, provides a pressure controllable detection device for a test of an SF6 gas-insulated switchboard. The device comprises a car body with a lifting platform and a driving mechanism is arranged on the car body to realize the lifting and landing of the lifting platform. At least one test mechanism is arranged at one end of the lifting platform; the test mechanism comprises an insulating sleeve, a touch contact, a compression spring, a pressure sensor and test wiring; the insulating sleeveis mounted at one end of the lifting platform in a sliding mode; the touch contact is movably sleeved outside the insulating sleeve; the compression spring is arranged between the insulating sleeve and the touch contact; the pressure sensor is arranged between the compression spring and the touch contact; and one end of the test wiring is connected with the touch contact electrically. The device also comprise a controller; the input end of the controller is connected with the pressure sensor; and the output end of the controller is connected with the driving mechanism. The device provided in the invention has the advantages of providing convenience for realization of a wiring operation of the SF6 gas-insulated switchboard test, time and effort saving in the wiring operation, and good wiring effect.

Description

technical field [0001] The invention relates to the technical field of auxiliary testing equipment for SF6 inflatable cabinets, in particular to a pressure-controllable detection device for testing SF6 inflatable cabinets. Background technique [0002] SF6 inflatable cabinet is a kind of sealing high-voltage components, such as circuit breakers, isolating switches, load switches, grounding switches, transformers and bus bars, etc., in a closed shell filled with lower pressure (generally 0.02 ~ 0.05MPa) SF6 gas Metal-enclosed switchgear. In 1982, Siemens took the lead in developing the SF6 insulated circuit breaker cabinet. After that, the inflatable cabinet products developed rapidly, and various series of products were launched one after another. Due to the structural advantages of the SF6 inflatable cabinet and not being affected by the external environment, it can be used in general air insulated cabinets that cannot Places where it is used, such as large temperature cha...
