Conductor joint heating monitors sensor, belongs to power sensor technical field.
Background technique
Distribution bus is the basic building block of power transformer, power distribution station or power distribution room, for small distribution room due to
Its supply current is smaller, and the heat condition of low-voltage distribution busbar joint is not necessarily to monitoring, but for large-size machine or industrial electro
Such as dig up mine well, rubble field, steel rolling mill, steel mill, Bricks and Tiles Plant and its energy consumption of sea port dock of the industrial and mining enterprises of furnace is higher, moves
The operating current of power electricity is larger, and a few thing often makes power transformer secondary low in the electrical appliance exchanged under 380 volts of voltages
Pressing the current strength in distribution bus is more than 100 amperes, and some reaches hundreds of amperes, in the case where such high current, distribution
The heat condition of busbar joint be it is very important, need to be detected regularly, but due to these distribution facilities near
Electromagnetic field intensity is very big, if electricity consumption, magnetic or electromagnetic type sensor is ratio come the heat condition for detecting distribution bus connector
More difficult to be easy in other words by environment 50Hz Hz noise, current Main is mainly looked into first is that manually estimate
See that paint has the three-phase bus joint of red yellowish green trichromatism paint phase mark whether to change colour, burn or smoke event respectively；Second is that
Regular circling measurment is carried out by hand-held infrared thermometer, the former deficiency is that range estimation precision is very low, can not know joint
