Including the base with arrange the three resistance container of placing the base top in in proper order, the bottom of resistance container is equipped with the transversal semicircle - shaped's of personally submitting two and inserts the ring, two insert the ring is the symmetrical arrangement form that the semicircle mouth is relative, two insert and are equipped with the clearance between the ring, two all are equipped with the voussoir on inserting the outer wall of ring, set up on the base to supply to insert and encircle the socket of planting, two external diameters of inserting the ring are greater than the internal diameter of socket, offer the draw -in groove on the inner wall of socket, the voussoir joint in the draw -in groove in. Insert two of resistance container on the ring extrudees the socket to the base on through the mould. Because two insert and set up the clearance between the ring, two insert principles that the ring constitutes the expansion pipe forms heads and squeezes in socket, afterbody and rise and tightly make resistance container and the base constitution to be connected the cooperation. Simultaneously two insert voussoir on the ring outer wall and take advantage of a situation in the draw -in groove of card on the socket. And then guarantee the resistance container and be connected with the firm of base, eliminate resistance container and base seal failure's hidden danger within a definite time.
Description
Technical field
This utility model relates to electrical equipment, is specifically related to a kind of Three phase combination overvoltage protector housing.
Background technology
Three phase combined over-voltage protector is mainly used in the electric power network of generating, power supply and electricity consumption enterprise.It is used for protecting the electrical equipments such as transformator, switch, bus, motor, atmospheric over-voltage can be limited and switching overvoltage that various switch causes, alternate and relatively overvoltage all can be played reliable restriction effect, protect insulation of electrical installation to be without prejudice.It is widely used in the overvoltage protection of electrical equipment in the industries such as electric power, metallurgy, chemical industry, coal, oil, light industry.
Three phase combined over-voltage protector housing mainly equips the overcoat of three phase combined over-voltage protector resistance, it includes base and the be set with resistance container on base, three phase combined over-voltage protector housing is mainly used and is pressed on base by mould by resistance container, form Integral pressed type structure to ensure the sealing of three phase combined over-voltage protector, resistance container is generally used directly to be punched on base between existing resistance container and base, there is the hidden danger that resistance container comes off with base, and then there is the hidden danger of seal failure between resistance container and base.
Summary of the invention
This utility model purpose is to provide a kind of Three phase combination overvoltage protector housing, it is ensured that firm between resistance container and base is connected, and then eliminates the hidden danger of seal failure between resistance container and base.
In order to realize object above, the technical solution adopted in the utility model is: a kind of Three phase combination overvoltage protector housing, including base and the be set with three resistance containers above base successively, the bottom of resistance container is provided with two slotting rings of cross section semicircular in shape shape, two slotting rings be semicircular opening relative be arranged symmetrically with shape, it is provided with gap between two slotting rings, it is equipped with voussoir on the outer wall of two slotting rings, the socket planted for slotting ring is set on base, the external diameter of two slotting rings is more than the internal diameter of socket, draw-in groove is offered on the inwall of socket, described voussoir is connected in described draw-in groove.
Two slotting rings of resistance container are extruded on the socket to base by of the present utility model having the technical effect that by mould.Owing to arranging gap between two slotting rings, the principle formation head of two slotting rings composition expansion tubes clamp-ons socket, afterbody tensioner makes resistance container be connected cooperation with base composition.Voussoir on two slotting ring outer walls is taken advantage of a situation in the draw-in groove being stuck on socket simultaneously.And then ensure that resistance container is connected with the firm of base, eliminate the hidden danger of seal failure between resistance container and base.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention
Referring to the drawings, a kind of Three phase combination overvoltage protector housing, including base 10 and the be set with three resistance containers 20 above base 10 successively, the bottom of resistance container 20 is provided with two slotting rings 21 of cross section semicircular in shape shape, 22, two slotting rings 21, 22 relative in semicircular opening are arranged symmetrically with shape, two slotting rings 21, gap it is provided with between 22, two slotting rings 21, voussoir 23 it is equipped with on the outer wall of 22, the socket 11 planted for slotting ring 21 is set on base 10, two slotting rings 21, the external diameter of 22 is more than the internal diameter of socket 11, draw-in groove 12 is offered on the inwall of socket 11, described voussoir 23 is connected in described draw-in groove 12.
By mould by the socket 11 in two slotting ring 21,22 extruding of resistance container 20 to base 10.Owing to arranging gap between two slotting rings 21,22, the principle formation head of two slotting rings 21,22 composition expansion tubes clamp-ons socket 11, afterbody tensioner makes resistance container 20 be connected cooperation with base 10 composition.Voussoir 23 on two slotting ring 21,22 outer walls is taken advantage of a situation in the draw-in groove 12 being stuck on socket 11 simultaneously.And then ensure that resistance container 20 is connected with the firm of base 10, eliminate the hidden danger of seal failure between resistance container and base.
Further, the ladder type shape that described voussoir 23 is big in head handle, the cross sectional shape of draw-in groove 12 vallecular cavity is consistent with the cross sectional shape of voussoir 23.
Owing to 23 handles of voussoir are big, such voussoir 23 easily imports in socket 11 from head to tail, and then easily imports in draw-in groove 12.
Preferably, the bottom of resistance container 20 is positioned at two slotting ring 21,22 peripheries and sets and offer cannelure 24, is disposed with annular insulated enclosure pad 30 in cannelure 24.
Existing resistance container 20 mainly relies on resistance container 20 to coordinate the sealing of outer edge against position with base 10 with sealing of base 10, the annular insulated enclosure pad 30 arranged forms resistance container 20 and coordinates the sealing of inner edge against position with base 10, is further ensured that the sealing effectiveness between resistance container 20 and base 10.
Additionally, the resistance container 20 of this structure uses silica gel material, in addition to having the electrical characteristic of common porcelain bushing type, also having a good insulation preformance, dielectric strength is high, anti-galvanic corrosion, and ageing-resistant, volume is little, and sealing is strong and the advantage of antidetonation.
