1, the device distribution of switch cubicle is in 4 separate compartments, breaker chamber, bus-bar room, cable vault, control room respectively, because heat generating spot is in sealed cabinet, operating cabinet gate inhibition only opens, operator on duty cannot detect the temperature of switch internal particularly contact by formal approaches, so the generation once contact heating seriously must cause the accident, influential system safe operation;
2, the position that middle-high voltage switch is the most easily generated heat is dynamic/static contact, due to the reason such as this location contacts is bad, dirty, contact resistance is comparatively large, and in big current situation, the thermal power at this place is very large, and consequently conductor joint heating is serious, the oxidation of aggravation contact-making surface, contact resistance is increased further, forms vicious circle, after developing into certain phase, then can cause serious fault, destroy system stable operation;
3, the improper mainly construction quality problem of the mounting process of equipment, in switch cubicle, the position of the dynamic and static contact of trolley type switch is with fixing plug position if any deviation, and switch pushes rear plug portion and just may contact unreal, causes loose contact, causes contact to generate heat;
4, when making, the assembling existing problems of equipment, when contact off-capacity or loose contact, this place's local temperature raises, and blows this place's contact, cause power outage time serious;
5, cannot be received and gather the data message uploaded of each detector tube control terminal and all kinds of statistical report form by the Internet, can not to each monitoring pipe control terminal remote monitoring and administration;
6, real time on-line monitoring can not realize, and the equipment of online cannot be utilized all to can be used as watch-dog, as computer, smart mobile phone, PAD etc. check each statistics and form in system;
7, can not realize long-rangely taking remote measurement to each switch cabinet, remote signalling and remote control;
8, whether switch cubicle exists dew condensation phenomenon, cannot be judged by the detection data of equipment for surfing the net.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of monitoring device effectively monitoring middle-high voltage switch humiture and current loop temperature thereof.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The overheated monitoring device of middle-high voltage switch current loop, comprise cabinet, bus-bar room, cable vault, control room and breaker chamber is provided with in cabinet, bus-bar room is fixed with contact box near the side of breaker chamber by mounting panel, fixed contact is provided with in contact box, fixed contact contacts with bus, and the moving contact of breaker chamber inner breaker stretches in contact box; In addition; also comprise the temperature transducer I for monitoring bus temperature, for monitoring the temperature transducer II of fixed contact temperature and the Microcomputer Protection device for communications; temperature transducer I and temperature transducer II wirelessly accesses Microcomputer Protection device to upload the data recorded, and Microcomputer Protection device is located in control room.
Described temperature transducer I and temperature transducer II is sticked on bus and fixed contact respectively by bond plies.
Be provided with Temperature Humidity Sensor in described cable vault, Temperature Humidity Sensor accesses Microcomputer Protection device by wireless or wired mode.
Compared with prior art, the utility model has the advantages that: after the utility model access network, the humiture in middle-high voltage switch can be monitored long-range, in real time, thus in time prevention switch cubicle because bus temperature is too high, contact because of off-capacity or the loose contact security incident caused that causes local temperature to cross high reason, improve switch cubicle reliability of operation.
