Description

A kind of low voltage drawing-out switching carbinet
Technical field
The present invention relates to a kind of low voltage drawing-out switching carbinet, belong to electrical equipment。
Background technology
Rapid growth along with national economy in recent years, power network development also welcomes new historic opportunities, MNS type low voltage drawing-out switching carbinet is applicable to power plant, transformer station, petrochemical industry, metallurgical steel rolling, the industrial enterprise such as industry light industry textile industry and residential quarters, the places such as skyscraper, as exchange 50 ~ 60Hz, the use of electric energy conversion, distribution and the control of the controller switching equipment of rated operational voltage 660V and following power system。
But in actual applications, the some shortcomings that switch cubicle itself exists also occur therewith, as lacked temperature monitor system etc. in main transformer low voltage incoming line switch cabinet easily overheated, cabinet, these problems will hide some dangers for safety in production if do not found counter-measure。Switch cubicle is easily produced superheating phenomenon by the impact of various factors, will be substantially reduced apparatus insulated, and jeopardize equipment safety operation time serious。
Now commonly used cabinet nipple heating supervision method mainly has: paste thermometric wax disk(-sc) at joint;Hands touches cabinet door perception in-cabinet temperature;Overheated by unusual odor discovering device;Overheated etc. by abnormal sound equipment discovering device。Pasting thermometric wax disk(-sc) is the thermometry that outdoor joint is conventional, and being used in enclosures has very big limitation, and major part joint be can't see by the observation window of cabinet door, can only check when switching interruption maintenance that joint is with or without overheat condition, and the effect of preventing accident is little。Hands touches the method for cabinet door, and can probably to judge that temperature has without exception, Zuo Anmen transformer station at substation management place once found 2 serious conductor joint heating faults by the method, but this method has very big randomness and occasionality, and due to the difference of individual's sensation, same case also has different judgement。When there being overheated joint, necessarily having unusual odor or abnormal sound, when particularly connecting the conductor joint heating of current transformer, it is possible to send strong unusual odor, staff can make further judgement according to the source of abnormal smells from the patient。In a word, can probably be judged with or without conductor joint heating fault in switch cubicle by the above several method of integrated application, but not science, not rigorous, to unwatched transformer station, Switching Station without practical value。?
How finding that the conductor joint heating fault in switch cubicle is always up one of problem of research by the method for science, people have carried out test of many times and discussion in this respect。Existing technology is often taked direct monitoring method, mounting temperature sensor on joint, temperature signal is focused on, it is judged that whether connector temperature exceedes permissible value。Its technological difficulties are that the installation of temperature sensor and temperature signal are by the transmission of sensor to datatron。Requiring that temperature sensor is directly installed on joint, its volume has strict restriction, it is impossible to the insulation of impact switch is with properly functioning。Signal transmits and uses wired mode is definitely unallowed, there is highfield magnetic interference and the masty problem of discharger power supply by wireless transmit。
