Heating sensor for power distribution bus joint

Abstract

The invention provides a heating sensor for a power distribution bus joint. The heating sensor includes a housing, a panel, an alcohol column, scales, an annular glass tube, an annular lens, a circuitboard I, a circuit board II, a sleeve, a connecting rod, a shielding box, a stator support, a movable sheet support, a fixed sheet group, a rotor group, an insulating support, a telescopic box, a backlight sheet, a cover I, an annular cover II, a heat gathering box, a heated sheet, a frame-shaped support, an induction coil, supporting legs, a hose, an LED, a rectifying circuit, a filter circuit,a voltage stabilizing circuit, a bar code memory a storage battery, a variable capacitor, an inductor and a transistor. The housing, a partition plate, the shielding box, the frame-shaped support, a first box, a second box, an annular cover I, the annular cover II and the supporting legs form a support mechanism. The annular glass tube, the alcohol column, the annular lens, the backlight sheet andthe scales form a reading mechanism; and the heated sheet, the telescopic box, the connecting rod, the fixed sheet group and the movable sheet group form a sensing mechanism. The sensor can reduce the labor intensity of workers, and remote detection is carried out through carrier transmission.

Description

technical field [0001] The invention relates to a temperature sensor for detecting a power distribution bus, in particular to a heat sensor for a joint of a power distribution bus, which belongs to the technical field of power monitoring. Background technique [0002] The power distribution busbar is the basic component of a power transformer, power distribution room or power distribution room. For a small power distribution room, due to its small supply current, the heating of the low-voltage distribution busbar joints does not need to be monitored, but for large motors or industrial electric furnaces Industrial and mining enterprises such as mining shafts, gravel yards, rolling mills, steel mills, brick and tile factories, and seaport terminals have high energy consumption, and the working current of power electricity is relatively large. Some electrical appliances that work under AC 380 volts often Make the current intensity of the secondary low-voltage distribution bus o...

[0002] The power distribution busbar is the basic component of a power transformer, power distribution room or power distribution room. For a small power distribution room, due to its small supply current, the heating of the low-voltage distribution busbar joints does not need to be monitored, but for large motors or industrial electric furnaces Industrial and mining enterprises such as mining shafts, gravel yards, rolling mills, steel mills, brick and tile factories, and seaport terminals have high energy consumption, and the working current of power electricity is relatively large. Some electrical appliances that work under AC 380 volts often Make the current intensity of the secondary low-voltage distribution bus of the power transformer exceed 100 amperes, and some reach hundreds of amperes. Under the condition of such a large current, the heat generation of the distribution bus joint cannot be ignored, and regular inspections are required. The current method is first to rely on manual visual inspection, mainly to check whether the three-phase bus joints painted with red, yellow and green three-color paint phase marks are discolored, burnt or smoked; the second is to conduct regular inspections through hand-held infrared thermometers The disadvantage of the former is that the accuracy of visual inspection is very low, and the specific temperature at the joint cannot be known. The disadvantage of the latter is that the labor intensity is relatively high, and the staff need to walk back and forth in the power distribution room frequently
