Filtering pulse capacitor operation temperature rising control device

Technical field

The utility model relates to a kind of temperature rising control device, especially filtering pulse capacitor operation temperature rising control device.

Background technology

Existing filtering pulse capacitor is to be arranged in housing after a plurality of capacitance components are connected, then seals pour into certain vegetable oil in housing after.Enclosure interior is the space of sealing, and filtering pulse capacitor when work, its inside all can generate heat conventionally, and capacitance component sends out heat thermogenetic and mutually conduct, and causes enclosure interior temperature higher.If heat accumulation is more, each capacitance component has the danger that explosion occurs, and when serious, blasts.Any one capacitance component is blasted, and whole capacitor all will lose efficacy, and cannot keep in repair use, and brings potential safety hazard.

Utility model content

The deficiency that the utility model exists for prior art just, provides a kind of filtering pulse capacitor operation temperature rising control device.

For addressing the above problem, technical solution adopted in the utility model is as follows:

Filtering pulse capacitor operation temperature rising control device, be arranged on the housing of sealing, a plurality of capacitance components are installed in housing, described temperature rising control device comprises: heat sensor and temperature controller, in capacitance component one side, heat sensor is installed, and heat sensor directly contacts with each capacitance component, in outside, is provided with temperature controller, and temperature controller is connected with heat sensor.

Compared with prior art, implementation result of the present utility model is as follows for the utility model:

Filtering pulse capacitor described in the utility model operation temperature rising control device, by temperature controller is set, can timing monitoring capacitor internal temperature conditions, and in case of emergency cut off the electricity supply.Like this, not only efficiently solve internal temperature timing monitoring, prevent the danger that capacitor is blasted simultaneously, stopped potential safety hazard.

Accompanying drawing explanation

Fig. 1 is filtering pulse capacitor operation temperature rising control device structural representation described in the utility model;

Fig. 2 is filtering pulse capacitor internal structure schematic diagram described in the utility model;

Fig. 3 is the left view of Fig. 1.

Embodiment

Content of the present utility model is described below in conjunction with specific embodiments.

As shown in Fig. 1 ~ Fig. 3, filtering pulse capacitor described in the utility model comprises the metal shell 1 of sealing, and a plurality of capacitance components 2 are installed in housing 1.Heating during due to capacitance component 2 work, heat, in the interior mutual conduction of housing 1, causes its internal temperature higher.

Filtering pulse capacitor described in the utility model, is provided with heat sensor 3 in capacitance component 2 one sides, and heat sensor 3 directly contacts with each capacitance component 2.In housing 1 outer setting, have temperature controller 4, temperature controller 4 is connected with heat sensor 3.Heat sensor 3 shows the inner parameters such as transient temperature by temperature controller 4.Generally, when internal temperature is during higher than 80 ℃, temperature controller 4 starts action, cuts off the electricity supply, and plays like this effect of protection electric capacity.

Filtering pulse capacitor described in the utility model, by temperature controller is set, can timing monitoring filtering pulse capacitor internal temperature situation, and in case of emergency cut off the electricity supply.Like this, not only efficiently solve internal temperature timing monitoring, prevent the danger that capacitor is blasted simultaneously, stopped potential safety hazard.
