Abstract

The utility model relates to a fully closed dry discharge coil, comprising an iron core, a coil, and a high-voltage and a low-voltage terminals which are respectively connected with the coil. The utility model is characterized in that the iron core and the coil are poured in full seal in the dry insulating body of a curved surface external shape composed of a plurality of umbrella flared bodies; the high-voltage terminal is arranged on the upper end of the dry insulating body; the low-voltage terminal is arranged on the bottom of the dry insulating body. With a reasonable structure, the utility model has the advantages of small volume and small volume; the utility model is not limited by the external condition of climatic environment, such as temperature, humidity, dirt, etc., with long service life.

Description

Totally-enclosed dry type discharge coil
The utility model relates to a kind of and the matching used discharge coil of Shunt Capacitor Unit.
Therefore open type dry type discharge coil in the prior art can only be used for indoorly because iron core, coil are exposed in the air fully, and indoor environmental condition is had relatively high expectations, and as indoor relative humidity, cleanliness factor all has strict requirement; Though the oil immersed type discharge coil can be used for indoor and outdoor, and is bulky, be not suitable for the limited place of installing space, often be prone to the oil seepage phenomenon in addition, bring big difficulty for the maintenance between the operating period.
The purpose of this utility model is to provide a kind of totally-enclosed dry type discharge coil for overcoming above-mentioned deficiency of the prior art, makes its volume little, in light weight; Be not subjected to environmental influence, to satisfy practical application.
The utility model is to realize with following technical proposal: it comprises iron core and is wound on coil on the iron core, the high and low pressure terminal that is connected respectively with coil, wherein iron core and coil are totally-enclosed is cast in the curved profile dry state insulator that is made of a plurality of full skirt bodies, HV Terminal is positioned at two protrusion tops of insulator, and low-voltage terminal is positioned at the insulator bottom.
The utility model is a kind of totally-enclosed dry type discharge coil, and it has adopted the insulation curved body profile that is made of a plurality of full skirt bodies, makes and smaller volume can satisfy the limited user's request of installing space, does not also have the sorrow of leakage of oil; Compare with open type dry type discharge coil,, not restricted by external conditions such as climatic environment such as temperature, humidity, filth because be totally enclosed type and adopted the weatherability insulating material; Owing to be so that the moulding by casting structure is extremely sturdy and durable; Advantages such as it is low to have loss, and discharge effect is good.
Be described with reference to the accompanying drawings the utility model overall structure.
Fig. 1 is this discharge coil overall structure cut-away section front view.
Fig. 2 is this discharge coil base upward view.
As shown in Figure 1; it has coil 3, iron core 4, HV Terminal 1; low-voltage terminal 6; the high and low pressure terminal is connected with coil 3 respectively; iron core and coil are cast in the curved profile dry state insulator 2 that is made of a plurality of full skirt bodies by totally-enclosed; two HV Terminal 1 lay respectively at two tops that insulator protrudes, and two low-voltage terminals are positioned at the insulator bottom, and iron core and installation connect ground protections with bolt 7.When manufacturing, the iron core that is wound with coil is fixed in the mould with bolt 5, coil adopts welding method to be connected with the high and low pressure terminal respectively by copper cash.Shown in Fig. 1,2: above each one adopts casting resin.A vacuum pouring is in a mould, in 130 ℃~140 ℃ a few hours cure and demold moulding.
