Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of Fig. 1.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of dual explosion-protection equipment for capacitor, the capacitor packet
Include end cap 1, the binding post 2 being installed on the end cap 1, capacitor casing 3, capacitance core 4 and the capacitance core connecting with capacitance core 4
Conducting wire 41.The dual explosion-protection equipment includes for controlling the gas bleeder valve 8 of 3 air pressure inside of capacitor casing, set on described
The explosion-proof block 5 and sheet metal 6 of 1 bottom of end cap.The gas bleeder valve 8 is installed on the end cap 1, and the sheet metal 6 is adjacent to fixation
In the lower end surface of the explosion-proof block 5, the capacitance core conducting wire 41 is connected on the sheet metal 6；The lower end surface of the explosion-proof block 5
Equipped with multiple grades of items 51, the shelves item 51 is set to the two sides of the sheet metal 6, to increase climbing between the adjacent sheet metal 6
Resistance.And discharge resistance 61 is connected between the adjacent sheet metal 6, the two sides of the discharge resistance 61 are equipped with described
Shelves item 51.
First through hole 52 corresponding with the binding post 2 is offered on the explosion-proof block 5, the binding post 2 passes through institute
It states first through hole 52 to be in contact with the sheet metal 6, to realize being electrically connected for binding post 2 and sheet metal 6.
Specifically, the lower end of the gas bleeder valve 8 is equipped with communicating pipe 9, and the communicating pipe 9 is connected to the gas bleeder valve 8, described
Communicating pipe 9 passes through the end cap 1 and protrudes into the capacitor casing 3.The side wall of the communicating pipe 9 offers multiple air inlets
91, the gas in the capacitor casing 3 enters from the air inlet 91, is discharged by the gas bleeder valve 8.
Since the capacitance core 4 is generally fixed in the capacitor casing 3 by way of encapsulating, when capacitor is sent out
When raw failure, a large amount of heat can be generated and melt colloid, blocking described in the colloid for causing the air inlet that can be splashed, thus
Can not work normally the gas bleeder valve.Therefore, the bottom of the communicating pipe 9 is equipped with baffle 92, makes colloid that can not splash in institute
It states on communicating pipe, guarantees the normal work of the gas bleeder valve.
On the other hand, the top of the gas bleeder valve 8 is equipped with connector lug 81, the connector lug 81, communicating pipe 9, end cap 1 and lets out
Air valve 8 is made of metal material, and therefore, the setting of the connector lug 81 and gas bleeder valve 8 can be used for connecting ground wire.
The explosion-proof block is fixedly connected on the bottom of the end cap 1, and the binding post 2 passes through the end cap 1, and installation is fixed
In the middle part of the end cap 1.The edge of the upper surface of the explosion-proof block 5 is equipped with surrounding edge 7, so that the explosion-proof block 5 and the end
Lid 1 forms cavity 71 after being fixedly connected, therefore when bulging occurs in capacitor casing 3, the cavity 71 can gather high pressure gas,
Corresponding end cap portion described in cavity 71 is set to heave deformation.The end cap 1 can take up the binding post 2 after heaving, make institute
It states binding post 2 to separate with sheet metal 6, and then realizes the cutting of route.
Moreover, making the end cap 1 be easier to heave to improve the explosion-proof sensitivity of the utility model, the surrounding edge 7 is set
There is the notch 72 for the cavity 71 exhaust or air inlet, the explosion-proof block 5 offers multiple for balancing in the cavity 71
The venthole 53 of air pressure.Meanwhile the design of the notch 71 and venthole 53, the gas release in the cavity 71 can be accelerated,
Make the variation synchronous with ambient pressure of the air pressure inside cavity 71.Avoid staff dismantle this it is practical when, the cavity
71 also in the state of release gas.
Further, the end cap 1 is equipped with corresponding with the surrounding edge 7 impression (not shown in figure), i.e. end cap 1
It can be become thinner at impression, so that the end cap 1 be made to be easier to heave.
The upper surface of the explosion-proof block 5 is equipped with guiding groove 54 corresponding with the first through hole 52, so as to the end cap
1 with explosion-proof block 5 be connected and fixed when, the binding post 2 may be guided and be inserted into the first through hole 52, so improve the utility model
Production efficiency.Preferably, the guiding groove 54 is in truncated cone-shaped.
In order to reinforce the explosion-proof intensity of the utility model, the upper surface of the explosion-proof block 5 is equipped with multiple first reinforcing ribs 55,
First reinforcing rib 55 is set to the two sides of the first through hole 52.
On the other hand, the lower end surface of the explosion-proof block 5 is equipped with the second reinforcing rib 56, and the height of second reinforcing rib 9 is big
In the thickness of the discharge resistance 61.Second reinforcing rib 56 is set to the two sides of 5 lower end surface of explosion-proof block.Due to described
Discharge resistance 61 is easy to happen when transporting mobile or stacking on assembly line and carrying to fall off.In this regard, second reinforcing rib 56
Height is greater than the thickness of the discharge resistance 61, can the hanging discharge resistance when so that the lower end of the explosion-proof block 5 is face-down
61, it avoids it from directly contacting with the transmission belt of elementary stream, to reduce falling off for discharge resistance, improves the yields of product.
It should be noted that the end cap 1, after heaving, under normal circumstances, the middle part bulge height of end cap 1 is most
Greatly, when the intensity deficiency of the explosion-proof block 5, explosion-proof block is easy to be broken off or bending, and the sheet metal in explosion-proof block is caused to be easy
Heaving and being adjacent to binding post 2 for end cap 1 is followed, so as to cause that can not completely cut through route and prevent the generation of explosion.
To sum up, when capacitor failure, the high pressure gas formed in the capacitor casing 3 can first heave the end
Lid 1 cuts off the connection of the binding post 2 and sheet metal 6, prevents capacitor from continuing fever and the air pressure of gas rising, avoids
The generation of explosion.
Fail to heave completely when the end cap 1, it is described when leading to part line column and sheet metal also in connection status
Air pressure in capacitor casing 3 will continue to increase, and after air pressure reaches the preset value of the gas bleeder valve, the capacitor protector can be discharged
Gas in body 3 prevents air pressure from continuing to increase, and then prevents the generation of explosion.
It should be noted that explosion, which occurs, for capacitor refers to that the gas in the capacitor casing 3 washes the end cap open
1, required atmospheric pressure value is greater than the discouraged atmospheric pressure value of the gas bleeder valve 8, and the discouraged atmospheric pressure value is greater than the end cap 1 and heaves
Required atmospheric pressure value.Therefore, the utility model can preferentially take the mode of cutting circuit, the first stopping capacitor before explosion
Continue to generate heat, prevent the continuous raising of air pressure, is then carried out by the way of gas bleeder valve again dual explosion-proof.The above is this reality
With novel preferred embodiment, it is noted that for those skilled in the art, practical not departing from
Under the premise of new principle, several improvements and modifications can also be made, these improvements and modifications are also considered as the guarantor of the utility model
Protect range.
