Description
Technical field
The utility model relates to a kind of electronic component, specifically a kind of explosion-proof power capacitor with security control function.
Background technology
After a long time use, inside is easy to produce heat energy capacitor, causes internal pressure to raise.When pressure is elevated to certain numerical value, be easy to cause the condenser breakdown even situation of capacitor explodes to occur.
Existing capacitor mainly adopts when preventing capacitor internal hypertonia increases relief valve to carry out internal pressure relief, traditional relief valve is as structure disclosed in number of patent application " 201310400664.2 ", mainly comprise: explosion-proof plug, seal one, anti-explosion set, described explosion-proof plug and described anti-explosion set screw thread nested arrangements, described seal one is between described explosion-proof plug and described anti-explosion set, also comprise spring and lower compact heap, described explosion-proof plug axle center place is provided with through hole, in described through hole, top is provided with position limiting structure, in described through hole, below is provided with contraction mouth, described lower compact heap is arranged between described position limiting structure and described contraction mouth, described spring is between described position limiting structure and described lower compact heap.Described anti-explosion set is for being welded on the seal casinghousing of capacitor.
Said structure arranges spring due to needs, is therefore difficult to control the volume of explosion-proof valve in longitudinal direction.And due in capacitor internal pressure increase process, spring coverage can reduce, thus produce finedraw, at this moment the liquid of capacitor internal just can spill from finedraw.Meanwhile, this blast resistance construction is complicated, and production cost is high, is unfavorable for extensively promoting the use of.
Utility model content
The purpose of this utility model is the shortcoming existed to overcome prior art, and provide a kind of structure simple, easy to use, production cost is low, a kind of explosion-proof power capacitor with security control function of structural approach novelty.
The utility model object realizes with the following methods: a kind of explosion-proof power capacitor with security control function, is characterized in that: it Deformation Detection device comprising electric capacity body and be arranged on its appearance, Deformation Detection device and control system Electricity Federation.
Described Deformation Detection device comprises integral coating at the shell of capacitor surface and the swelling agent that is filled between the two, shell is provided with pressure sensor and control system Electricity Federation.
Described swelling agent is thermal grease conduction.
Described swelling agent is compressed air.
Described Deformation Detection device comprises the support being fixed on capacitive surface and the pressing plate covering electric capacity end face, and pressing plate is close to electric capacity end face and is arranged, and is provided with action sensor for detecting the displacement of pressing plate, action sensor and air system Electricity Federation between support and pressing plate.

The beneficial effects of the utility model are: 1, to have structure simple, easy to assembly for the utility model, the advantages such as production cost is low, and the market competitiveness is strong.2, utilize the Deformation Detection device detection capacitor being arranged on capacitive surface whether bulge to occur, the phenomenons such as expansion, prevent capacitor from blasting, there is the multi-efficiencies such as safeguard protection.3, the Deformation Detection device in this case and control system Electricity Federation, when detecting capacitor and being abnormal, send warning message or even deenergization in time, avoid the state of affairs to worsen further, thus avoid the generation of security incident, therefore can extensively promote be applicable to various power capacitor use.
Accompanying drawing explanation
Fig. 1 is the utility model first example structure schematic diagram.
Fig. 2 is the utility model second example structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.There is an explosion-proof power capacitor for security control function, it is characterized in that: it Deformation Detection device comprising electric capacity body 1 and be arranged on its appearance, Deformation Detection device and control system Electricity Federation.
As shown in Figure 1: described Deformation Detection device comprises integral coating at the shell 2 of capacitor surface and the swelling agent 3 that is filled between the two, shell 1 is provided with pressure sensor 4 and control system Electricity Federation.
Described swelling agent 3 is thermal grease conduction.
Described swelling agent 3 is compressed air.
As shown in Figure 2: described Deformation Detection device comprises the support 5 being fixed on capacitive surface and the pressing plate 5 covering electric capacity end face, pressing plate 5 is close to electric capacity end face and is arranged, action sensor 7 is provided with for detecting the displacement of pressing plate 6, action sensor 7 and control system Electricity Federation between support 5 and pressing plate 6.
Described action sensor 7 is sensitive switch.
Operation principle: arrange on existing electric capacity basis and be provided with this Deformation Detection device, as shown in Figure 1, it is the first embodiment of Deformation Detection device in this case, in this embodiment, capacitor surface is provided with shell, body seal is arranged, and fills swelling agent, and be provided with the pressure sensor with control system Electricity Federation within it in the space between its shell and electric capacity.When capacitor expands, during the tendency that deformation of cylindrical etc. explode, because the space between shell and electric capacity be have compressed, cause the pressure of swelling agent to change, thus shake-up pressure sensor send the signal of telecommunication to control system.
As shown in Figure 2, it is this structure second embodiment design sketch, before capacitor blasts, is first the tendency phenomenons such as its end face generation bulge, utilizes this characteristic, be provided with pressing plate and be connected with position transducer at the end face of capacitor in this case.When bulge occurs in electric capacity end, the crushed element of electric capacity promotes presser motion, thus touches the position transducer action be connected with pressing plate, and action sensor sends the signal of telecommunication to control system.Control system sends warning message, and when deflection exceedes certain limit, control system even can powered-down, prevents electric capacity from blasting.In a second embodiment, because Deformation Detection device and capacitor are split production, so it can facilitate user to install additional existing capacitor, thus be applicable to extensively promoting the use of.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; as the classification of swelling agent, the form etc. of action sensor, these changes and improvements all fall within the scope of claimed the utility model.
