Description
Technical field
The utility model relates to a kind of isolation switch device, especially for the armored middle-placed switch cabinet of high-voltage electric power system.
Background technology
Armored middle-placed switch cabinet structure is divided into three layers, and upper strata is bus and control room, and middle level is breaker chamber, and lower floor is cable vault.Middle-placed switch cabinet is simple in structure, volume is little, and price is low, is widely used in high-voltage electric power system.The parts such as a large amount of buses, cable and high-voltage switch gear are equipped with in middle-placed switch cabinet inside, and they link together by modes such as welding.Because middle-placed switch cabinet is in high-pressure work environment, so parts itself can produce a large amount of heat, especially their Nodes, resistance increases relatively, more easily produces heat.Like this, not only have influence on component working performance, and can be punctured, accidents caused.
Chinese patent CN201374518 discloses a kind of clad withdrawal-type AC metal-enclosed switch cabinet, on bus, bus head, is provided with bus temperature at thread detector, and bus temperature is electrically connected to temperature controller at thread detector.This scheme has solved the problem of temperature monitoring on bus, bus head, but it is by being electrically connected to, and structure is comparatively complicated, for generation heats such as cable adapter place, places, high-voltage switch gear contact, compared with many places, cannot detect.
Summary of the invention
Technical problem to be solved in the utility model is: solves the problem that above-mentioned prior art exists, and a kind of wireless temperature measurement middle-placed switch cabinet is provided, simplify the annexation of system for detecting temperature, and easy for installation, be not subject to limitation and the constraint of middle-placed switch cabinet inner structure position relationship.
The technical solution adopted in the utility model is:
A kind of wireless temperature measurement middle-placed switch cabinet, bus, cable and high-voltage switch gear are installed in cabinet, wherein, cable is all connected with bus with high-voltage switch gear, wireless temperature measurement sensor-based system is also installed in cabinet, wireless temperature measurement sensor-based system comprises temperature transducer and receiver, and temperature transducer and receiver are by the wireless communication that carries out.
In technique scheme, described temperature transducer is arranged on the joint of cable and bus or/and the Nodes of bus and bus, high-voltage switch gear contact place, and described receiver is arranged on middle-placed switch cabinet instrument door.
Compared to the prior art, system for detecting temperature of the present utility model adopts Radio Transmission Technology, and temperature transducer and receiver carry out wireless information transfer, have greatly simplified the annexation of system for detecting temperature, easy for installation, be not subject to limitation and the restriction of position relationship in middle-placed switch cabinet.
