Abstract
The utility model relates to a pulse capacitor with a pressure switch, which comprises a housing that is internally provided with a plurality of capacitor assemblies. The upper end surface of the housing is provided with two terminals. The upper end surface of the housing is provided with a pressure switch for sensing the internal pressure. The natural state of the pressure switch is a switched-off state. According to the pulse capacitor provided by the utility model, through arranging the pressure switch and an external monitoring circuit, the inner pressure state of the pulse capacitor can be appropriately monitored, and furthermore alarm warning is performed through an indicating lamp in emergency. Thus, not only is appropriate monitoring on the inner pressure effectively settled, but also the damage of capacitor explosion is prevented, and the potential safety hazard is eliminated.
Description
Technical field
The utility model relates to a kind of pulse capacitor, and especially a kind of pulse capacitor with pressure switch, belongs to capacitor technology field.
Background technology
Existing pulse capacitor be metallized film is rolled after, be arranged in housing, on housing, be provided with binding post, binding post is connected with metallized film exit, then seals pour into certain vegetable oil in housing after.While working due to pulse capacitor, its inside all can generate heat conventionally, and enclosure interior is the space of sealing, if heat accumulation is more, explosion very easily occurs the housing of capacitor, when serious, blasts.
Utility model content
The deficiency that the utility model exists for prior art just, provides a kind of pulse capacitor with pressure switch.
For addressing the above problem, technical solution adopted in the utility model is as follows:
Pulse capacitor with pressure switch, comprise housing, enclosure interior is installed a plurality of capacitance components, is provided with two binding posts on housing upper surface, the pressure switch that is provided with induction internal pressure on described housing upper surface, pressure switch nature is off-state.
Improvement as technique scheme, described pressure switch is connected with pressure monitor circuit, described pressure monitor circuit comprises display floater, indicator light, power supply, display floater shows the instantaneous value of enclosure interior pressure at any time, indicator light is reminded the internal pressure value of overstepping the extreme limit, and power supply provides power resources.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Pulse capacitor described in the utility model, by pressure switch and outer monitoring circuit are set, can timing monitoring pulse capacitor internal pressure situation, and in case of emergency by indicator light warning reminding.Like this, not only efficiently solve internal pressure timing monitoring, prevent the danger that capacitor is blasted simultaneously, stopped potential safety hazard.
Accompanying drawing explanation
Fig. 1 is a kind of pulse capacitor internal structure schematic diagram with pressure switch described in the utility model;
Fig. 2 is pulse capacitor pressure monitor circuit connection schematic diagram described in the utility model.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be a kind of pulse capacitor internal structure schematic diagram with pressure switch described in the utility model.Pulse capacitor described in the utility model comprises housing 1, the capacitance component 2 that a plurality of wiring as required of housing 1 inner installation connect, on housing 1 upper surface, be provided with two binding posts 3,4, binding post 3,4 is by inner capacitance component 2 access external circuits.
Pulse capacitor described in the utility model is also provided with pressure switch 5 on housing 1 upper surface, and pressure switch 5 can be responded to the pressure of housing 1 inner space.Pressure switch 5 natures are off-state, when the pressure value of overstepping the extreme limit, and pressure switch 5 closures, conducting pressure monitor circuit, when pressure returns to normal range (NR), pressure switch 5 disconnects naturally.
As shown in Figure 2, pulse capacitor pressure monitor circuit connection schematic diagram described in the utility model.Described pressure switch 5 is connected with pressure monitor circuit.Described pressure monitor circuit comprises display floater 6, indicator light 7 and power supply 8, and pressure switch 5 is connected with the power supply 8 of display floater 6, indicator light 7.When housing 1 pressure value of overstepping the extreme limit, pressure switch 5 closures, indicator light 7 work, remind the internal pressure value of overstepping the extreme limit.Display floater 6 shows the instantaneous value of internal pressure at any time, is convenient to timing monitoring.Power supply 8 is internal pressure monitoring etc. provides power resources.
Pulse capacitor described in the utility model, by pressure switch and outer monitoring circuit are set, can timing monitoring pulse capacitor internal pressure situation, and in case of emergency by indicator light warning reminding.Like this, not only efficiently solve internal pressure timing monitoring, prevent the danger that capacitor is blasted simultaneously, stopped potential safety hazard.
