A kind of capacitor of tape jam indicator lamp
Technical field
The utility model relates to a kind of capacitor, relates in particular to a kind of capacitor of tape jam indicator lamp.
Background technology
When capacitor internal excess Temperature will produce gas, in the time that reaching certain pressure, gas upper capacitor cover can be heaved to drawDisconnected wire makes capacitor break to reach the object of heat radiation from electrical network. But in actual use, wire often occurs can not be pulled offPhenomenon so that capacitor damage, the capacitor of existing tape jam indicator lamp does not have alarming device, can only go by staffObservation capacitor bulge phenomenon goes to judge the situation of capacitor, can not process in time like this emergency situations, is unfavorable for unified pipeReason. Therefore, how solving the above problems, is problem demanding prompt solution.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of capacitor of tape jam indicator lamp, and it can effectively solve electricityThe problem of not warning when internal tank is too high, has conveniently, safe and practical feature.
For realizing above-mentioned object, the technical solution adopted in the utility model is: a kind of capacitor of tape jam indicator lamp, comprisesCapacitor main body, wherein also comprises warning lamp, is provided with capacitance cover on capacitor main body, is provided with and can responds in capacitor main bodyThe thermistor of electric capacity internal temperature, described thermistor is electrically connected with warning lamp by fuse.
Further, the swivel nut being electrically connected with fuse is installed on described capacitance cover, in swivel nut, is provided with the spiral shell coordinating with itSilk, screw is electrically connected with described warning lamp.
Further, the screw terminal of described screw is provided with mount pad, and described warning lamp is fixed on mount pad and is electrically connected with screwConnect.
Further, between swivel nut and capacitance cover, be provided with sealing ring, described sealing ring is set on swivel nut.
Further, described fuse is self-healing fuse.
The utility model adopts above-mentioned technical scheme, by thermistor is set in capacitor, when temperature reaches thermistorPreset standard, the technique effect of warning to realize warning lamp by controlling the switch on and off of warning lamp, can allow staff fastSpeed the situation of electrolysis condenser, close in time capacitor with avoid damage; And by fuse is set, when electric current is greater than fuseTime, blown fuse is to reach the technical purpose of protective condenser.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local structure for amplifying schematic diagram in the A place of Fig. 1.
In figure, 1 is capacitor main body, 11 capacitance covers, and 2 is warning lamp, and 3 is thermistor, and 4 is fuse, 5For swivel nut, 6 is screw, and 61 is mount pad, and 7 is sealing ring.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of capacitor of tape jam indicator lamp, comprises capacitor main body 1, warning lamp 2, at electric capacityDevice main body 1 is provided with capacitance cover 11, is provided with the thermistor 3 of energy inductance capacitance internal temperature in capacitor main body 1, described inThermistor 3 be electrically connected with warning lamp 2 by fuse 4; The swivel nut being electrically connected with fuse 4 is installed on capacitance cover 115, in swivel nut 5, be provided with the screw 6 coordinating with it, screw 6 is electrically connected with described warning lamp 2; On the screw terminal of screw 6Be provided with mount pad 61, described warning lamp 2 is fixed on mount pad 61 and is electrically connected with screw 6; At swivel nut 5 and capacitance cover 11Between be provided with sealing ring 7, described sealing ring 7 is set on swivel nut 5; Fuse 4 is self-healing fuse. Warning lamp 2Comprise LED lamp, power supply, power supply is electrically connected with LED lamp by thermistor.
When in use, in the time that the temperature of capacitor main body 1 exceedes the default temperature upper limit of thermistor 3, thermistor 3Connect, at this moment warning lamp 2 lights to reach alarming effect; In the time that temperature drops to the default lowest temperature of thermistor 3, heatQuick resistance 3 disconnects, and at this moment warning lamp 2 extinguishes.
