Description
Technical field
The utility model relates to electric power storing device, a kind of specifically capacitor.
Background technology
The supporting capacitor of intelligent reactive power compensator in the market, or temperature detection is not set, or the laying temperature checkout gear is in the capacitor outside, can't really realize the capacitor behaviour in service is truly reflected, when detecting temperature anomaly, capacitor damages, or part is damaged, and makes capacitor can't produce due compensating action.Be placed on capacitor casing inside, owing to will fill a lot of silica gel between capacitor body and housing, heat conduction such as vaseline are not good materials, in fact the detected temperature of temperature sensor again, want deviation ratio bigger from actual temperature, reflection is also untimely in time.These all cause capacitor because operating voltage is too high, and harmonic wave is excessive and the internal temperature that causes raises, and can't in time cut off, and capacitor was lost efficacy, even short circuit, cause line fault.
The utility model content
At the defective that exists in the prior art, the purpose of this utility model is to provide a kind of capacitor, can reflect directly that capacitor is true, and real time temperature, temperature sensor directly are placed on fuse inside, when detecting temperature anomaly, by CPU, cuts off capacitor.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of capacitor, comprise shell 7, the bottom of shell 7 is provided with some installation foot rests 10, the binding post place of shell 7 top left is provided with protective cover 11, the top right-hand member is a control panel 1, described control panel 1 is provided with a CPU, be provided with some capacity cells 6 in the shell 7, it is characterized in that: also comprise at least one temperature sensor 5, described temperature sensor 5 is arranged on 6 temperature with accurate measurement capacity cell 6 of some capacity cells, and temperature sensor 5 is transferred to CPU by connecting lead-in wire 4 with temperature signal.
On the basis of technique scheme, the model of described CPU is STC90C58RD+, and the model of described temperature sensor 5 is water droplet temperature probe 5K3470.

Capacitor described in the utility model can reflect directly that capacitor is true, and real time temperature, temperature sensor directly are placed on fuse inside, when detecting temperature anomaly, by CPU, cuts off capacitor.
Description of drawings
The utility model has following accompanying drawing:
The structural representation of Fig. 1 capacitor
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of capacitor described in the utility model, comprise shell 7, the bottom of shell 7 is provided with some installation foot rests 10, the binding post place of shell 7 top left is provided with protective cover 11, the top right-hand member is a control panel 1, described control panel 1 is provided with a CPU, be provided with some capacity cells 6 in the shell 7, also comprise at least one temperature sensor 5, described temperature sensor 5 is arranged on 6 temperature with accurate measurement capacity cell 6 of some capacity cells, and temperature sensor 5 is transferred to CPU by connecting lead-in wire 4 with temperature signal.Described temperature sensor can be a thermistor.
On the basis of technique scheme, the model of described CPU is STC90C58RD+, and the model of described temperature sensor 5 is water droplet temperature probe 5K3470.
On the basis of technique scheme, described temperature sensor 5 is by the outer surface of silica stationary at contiguous capacity cell 6.
On the basis of technique scheme, the outer surface of each capacity cell 6 all is provided with a temperature sensor 5, and each temperature sensor 5 connects lead-in wire 4 by one respectively temperature signal is transferred to CPU.
Capacitor is being done under reactive power compensation or other the normal operating positions, the Chang Yinwei abnormity of power supply, cross high situation as harmonic wave, and cause the capacitor internal current excessive, condenser loss is increased, the internal temperature fast rise, cause the capacitor temperature too high in short time, internal pressure is excessive, causes capacitor the tripe that expands to occur, the final damage.Capacitor described in the utility model is placed on capacitor inside to temperature sensor, and capacity cell (capacitor body) is encapsulated in the housing together.More direct timely monitoring capacitor internal temperature truly reflects the capacitor operating position, prevents that to greatest extent exterior temperature change from exerting an influence to temperature sensor monitors capacitor internal temperature.Can in time use abnormal conditions to make reflection,, reach capacitor for voltage protection, prolong the capacitor purpose in useful life by cutting off capacitor to capacitor.
Temperature sensor detects variations in temperature and is transferred to CPU, CPU makes detected capacitor body internal temperature, do contrast with the temperature that is provided with, if the temperature anomaly of detecting (surpassing the safe temperature value of setting), CPU will send instruction and cut off the capacitor that has put into operation, and by the control display floater, show operation exception, be reduced to normal temperature up to the capacitor body internal temperature, CUP judges whether to drop into again capacitor according to the operating position that monitors.
