Description
Technical field
The utility model belongs to electric elements, is mainly used in the consumption reduction product that electric power system improves power factor of electric network, is a kind of dry-type high-voltage shunt capacitor specifically.
Background technology
High-voltage parallel capacitor is because the work field intensity of interior media is very high, so high-voltage parallel capacitor nearly all is the oil immersed type structure in the past.Along with transformer station does not have the raising of oiling requirement, at present in 35kV and the following transformer station except capacitor, other electric equipment has all been realized no oiling, therefore, the no oiling that how effectively and economically to solve high-voltage capacitor just becomes very important.
At present, domestic existing dry-type capacitor technology, it adopts the low pressure metal self-healing capacitor component is encapsulated in the case shell, the solid fire proofing material is filled in inside, during use, many capacitors are contained on the insulation stand, capacitors in series are become high-voltage capacitor from the outside.This structure has two shortcomings, and the one, capacitor is semi-insulating structure, i.e. the insulation against ground of capacitor will lean on the high-voltage strut insulator of other installation to bear, and causes wiring complexity, requirements of installation space bigger like this; The 2nd, to protect reliably inadequately, its protection way only is to reduce the loss of fault by fire proofing material, can not delicately single fault element be isolated.Therefore, existing dry-type capacitor technology says that totally cost height, reliability are not high enough, and this also is the main cause that causes present dry-type capacitor not popularize in an all-round way.
Summary of the invention
The purpose of this utility model is that will to overcome existing dry-type capacitor single capacitor rated voltage low excessively; need on the insulation stand, could form high-voltage capacitor and protect insecure shortcoming with many capacitors in series; a kind of dry-type high-voltage shunt capacitor is provided, makes it have good insulating, safe and reliable, single capacitor rated voltage height, characteristics simple in structure, easy to install.
The purpose of this utility model is achieved by the following technical solution: a kind of dry-type high-voltage shunt capacitor; comprise the case shell, be encapsulated in the capacitor element that links to each other in the case shell, the outlet terminal on the case shell; the capacitor element that it is characterized in that being encapsulated in the case shell is that connection in series-parallel connects, and described case shell outside is provided with the epoxyresin insulator protective layer.
Described capacitor element is the self-healing metallized capacitor element of band pressure fault protection.
At least the chamber that is divided into two insulation gaps in the described case shell, the capacitor element that all connection in series-parallel connect places corresponding cavity indoor respectively.
The utility model compared with prior art has many advantages and good effect:
1, the capacitor element that mainly adopts of dry-type high-voltage shunt capacitor of the present utility model is the element that is made of the internal pressure failure protection function that has self-healing metallization capacity cell.It is that the self-healing capacity cell that metallizes is packed in the canister of a sealing, when inner member breaks down, the gas pressure that fault produces outwards pushes up distortion with the canister top cover, thereby further will break the isolation that realizes fault element with the interior fuse that is connected the lead series connection.
2, the built-in case shell of the utility model employing can play the shielding action between inner member and the ground, has eliminated the partial discharge harm between element and the earth potential; Simultaneously, case shell inside provides a reliable space, and fault element was deformed and realizes the electricity isolation when inner member was broken down.
3, the whole case shell of the utility model outside adopts epoxy resin to make insulator, makes and directly satisfies high-tension requirement between capacitor element and the ground, and product promptly of the present invention is all insulation structure, can directly land to install and need not the stand that insulate.All with at present a large amount of oil immersed type capacitors that adopt are as broad as long from the mounting means to the wiring for single capacitor like this, use very convenient.Simultaneously, the epoxyresin insulator protective layer has also solved the problem that the iron-clad product gets rusty easily.
4, enforcement of the present utility model will make reliability improve greatly, and cost does not improve than existing dry-type high-voltage capacitor.
Description of drawings
Fig. 1 is the vertical view of dry-type high-voltage shunt capacitor of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to profile.
Embodiment
Below we are described in further detail the utility model in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2, be a kind of dry-type high-voltage shunt capacitor of the present utility model.Case shell 3 is the built-in case shell of a rectangular metal; the chamber that is divided into two insulation gaps in the case shell 3; the self-healing metallized capacitor element 4 of the some band pressure fault protections in two chambers connects by connection in series-parallel; the self-healing metallized capacitor element 4 of all band pressure fault protections is closed in the case shell 3, and the epoxyresin insulator protective layer 2 in case shell 3 outsides can form by cast.The end face on the case shell 3 be provided with 1, two outlet terminal 1 of two outlet terminals respectively with 3 liang of chambers of case shell in corresponding self-healing metallized capacitor element 4 link to each other.
Claims (3)
1, a kind of dry-type high-voltage shunt capacitor; comprise the case shell, be encapsulated in the capacitor element that links to each other in the case shell, the outlet terminal on the case shell; the capacitor element that it is characterized in that being encapsulated in the case shell is that connection in series-parallel connects, and described case shell outside is provided with the epoxyresin insulator protective layer.
2, dry-type high-voltage shunt capacitor according to claim 1 is characterized in that the self-healing metallized capacitor element of described capacitor element for the protection of band pressure fault.
