Preferably, solid insulation isolating switch 1 includes the first insulating part 5 and the second insulating part 6.First insulating part 5 is arranged on the outside of solid insulation isolating switch 1.Second insulating part 6 is arranged on the top of the first insulating part 5, and wherein, the first insulating part 5 and the second insulating part 6 are as the seal member outside solid insulation isolating switch 1, for solid insulation isolating switch 1 is carried out encapsulation process.The side of solid insulation isolating switch 1 and bottom surface can be wrapped by the first insulating part 5, form semi-closed state, again through coordinating with the second insulating part 6, solid insulation isolating switch 1 end face is sealed so that solid insulation isolating switch 1 is entirely sealed in the first insulating part 5 and the second insulating part 6 is internal.
According to embodiments of the present invention, coordinated by the first insulating part 5 and the second insulating part 6 and make solid insulation isolating switch 1 have good sealing effectiveness, thus preventing this solid insulation isolating switch 1 from operationally producing filthy and dew condensation phenomenon.
It is further preferred that the first insulating part 5 is wrapped in the outside of solid insulation isolating switch 1 and the long cylindrical structure that the first insulating part 5 is rectangular semiclosed scarce top cover.First insulating part 5 is the long cylinder insulating part of rectangular semiclosed scarce top cover, using second insulating part 6 top cover as this long cylinder insulating part, thus by fully wrapped around for solid insulation isolating switch 1.By adopting semi-enclosed first insulating part 5 and the second insulating part 6 as top cover to be sealed by solid insulation isolating switch 1, relative to adopting an integral insulation part, solid insulation isolating switch 1 is sealed, the embodiment of the present invention is easy for installation, also allow for dismounting and maintenance simultaneously, reduce cost.
Owing to solid insulation isolating switch 1 is wrapped by the first insulating part 5 and the second insulating part 6, first insulating part 5 and the second insulating part 6 can be that contact parcel with solid insulation isolating switch 1 can also be wrap up separated by a distance with solid insulation isolating switch 1, make it have totally-enclosed, all insulation, non-maintaining effect, greatly reduce the safety coefficient of switch surrounding.
Owing to the solid insulation isolating switch 1 of the embodiment of the present invention has the advantages such as totally-enclosed, all insulation, therefore this solid insulation isolating switch 1 can be used in three phase line, safely and effectively isolates power network current especially in 40.5KV high pressure power transmission and distribution cabinet.
Preferably, solid insulation isolating switch 1 also includes the second cluster parachute 7, and this second cluster parachute 7 is injection-moulded in the medial wall of the first insulating part 5 and the second insulating part 6.Owing to solid insulation isolating switch 1 is wrapped by the first insulating part 5 and the second insulating part 6, when the first insulating part 5 and the second insulating part 6 are arranged on the outside of solid insulation isolating switch 1, certain distance is had with solid insulation isolating switch 1, at medial wall injection moulding the second cluster parachute 7 that the first insulating part 5 is relative with solid insulation isolating switch 1 with the second insulating part 6, to increase the electric insulation distance within whole device.
It is further preferred that the second cluster parachute 7 engages with the first cluster parachute 3.As it is shown in figure 1, the second cluster parachute 7 by the medial wall at the first insulating part 5 and the second insulating part 6 engages with the first cluster parachute 3, it is effectively guaranteed the movement locus of solid insulation isolating switch 1.
Preferably, solid insulation isolating switch 1 also includes: the first metal insert 8 and the second metal insert 4.
First metal insert 8 is embedded in the inwall of the first insulating part 5.Second metal insert 4 is embedded in around cylindrical cylindrical surface, second metal insert 4 is contact, is used for connecting bus casing, or by major loop ground, wherein, the second metal insert 4 often rotate predetermined angular and the first metal insert 8 be connected to realize solid insulation isolating switch 1 deciliter.Can be uniformly inlay the second metal insert 4 around cylindrical cylindrical surface, by the second metal insert 4 and the first metal insert 8 with the use of, using the second metal insert 4 as contact, its one end is used for connecting bus casing, or by major loop ground.When the second metal insert 4 rotates predetermined angular, be connected with the first metal insert 8, when the second metal insert 4 does not rotate to predetermined angular, separate with the first metal insert 8, thus realize solid insulation isolating switch 1 deciliter.Wherein, predetermined angular can be 120 degree, i.e. when the second metal insert 4 rotates 120 degree, and the second metal insert 4 and the first metal insert 8 are connected.
According to embodiments of the present invention, can rotate to different directions owing to the second metal insert 4 rotates, different according to the direction that the second metal insert 4 rotates, thus realize solid insulation isolating switch 1 deciliter.Further, since the predetermined angular rotated is less, there is labour-saving effect.Due to solid insulation isolating switch 1 by rotate mode realize switch deciliter, with the isolation of direct acting switch compared with, reduce the space that whole isolating device is occupied.
Preferably, solid insulation isolating switch 1 also includes: bearing pin 10, blade 9 and stage clip 11.
End at bearing pin 10 is provided with axis hole, and this axis hole is installed with split pin 12.
Blade 9 is assemblied in the first metal insert 8 both sides, and centre bearing pin 10 connects.Being respectively fitted with blade 9 in the first inserts 8 both sides, two blades 9 are connected by bearing pin 10.Having a through hole on first metal insert 8, the bearing pin 10 described through hole of traverse is to connect described blade 9.This through hole can be manhole, it is also possible to be other through hole, and its effect is that therefore, this through hole need to be suitable with bearing pin 10 for through bearing pin 10.As it is shown in figure 1, blade 9 is arranged on the first metal insert 8 both sides, wherein, the end portion of blade 9 is longer than the first metal insert 8 so that the part grown of blade 9 is distributed in the second metal insert 4 both sides.
Stage clip 11 is arranged on the both sides of bearing pin 10 top cutter 9, is respectively provided with flat pattern packing ring at the two ends of stage clip 11, and this flat pattern packing ring is fixed by split pin 12.Being separately installed with stage clip 11 in the both sides of blade 9, the stage clip 11 in every one end is equipped with flat pattern packing ring, and this flat pattern packing ring is fixed by split pin 12.
According to embodiments of the present invention, by being equipped with stage clip 11, it is ensured that when blade 9 contacts with the second metal insert 4, have enough contact pressures.
