Abstract
The utility model relates to a load switch is with insulating barrel. It includes the body, and the body has the inner chamber, and it is made by insulating material. The upper end of body is the opening form, and there is vertical through -hole its bottom, and this vertical through -hole is linked together with the inner chamber of body. The seat of being qualified for the next round of competitions on the lateral wall of body, the seat of being qualified for the next round of competitions has horizontal through -hole, and the inner chamber of this horizontal through -hole and body is linked together. Have the baffle between the lateral wall at vertical through -hole and horizontal through -hole place, the baffle is a body coupling with the body. Its characteristics are the body inner wall that horizontal through -hole is relative, the baffle one side top -down that horizontal through -hole is relative all are the wave for this cross section of this body lateral wall, baffle all is the zigzag. The whole of this insulating barrel highly lower, the volume is less, is favorable to transportation and installation, also is favorable to promoting the miniaturized development of circuit breaker load switch cabinet or load switch combined electrical apparatus cabinet simultaneously.
Description
Technical field
The utility model relates to the power transmission and distribution parts that a kind of AC-HVDC and distribution network use, and is specifically to be arranged in the insulating cylinder body that circuit breaker loading switch cabinet or on-load switch combined electrical apparatus cabinet are used for holding on-load switch.
Background technology
All know in the manufacturing of power transmission and distribution device, in order to enable the on-load switch in circuit breaker loading switch cabinet or on-load switch combined electrical apparatus cabinet better use, people usually can to on-load switch installing insulating cylindrical shell.
At present, the on-load switch insulating cylinder body used in industry comprises body, and body has inner chamber, and it is made up of insulating material; The upper end of described body is opening-like, has vertical through holes bottom it, the intracavity inter-connection of this vertical through holes and body; A sidewall of described body has wire outlet seat, and wire outlet seat has cross through hole, the intracavity inter-connection of this cross through hole and body; Have baffle plate between the sidewall at described vertical through holes and cross through hole place, baffle plate is connected in one with body.According to current national standard, the creepage distance of on-load switch when combined floodgate and ground connection all must meet the standard being greater than 210mm.And the relative baffle plate one side of the relative inner body wall of the cross through hole of insulating cylinder body of the prior art, cross through hole is plane.Therefore, the height of baffle plate, and the relative body sidewall of cross through hole from upper end to the distance of combined floodgate tie point all than need 210mm be greater than, the requirement of national standard could be met.Like this, such that the whole height of insulating cylinder body is higher, volume is comparatively large, be unfavorable for transport and install, also limit the miniaturization trend of circuit breaker loading switch cabinet or on-load switch combined electrical apparatus cabinet simultaneously.
Utility model content
Problem to be solved in the utility model is to provide a kind of on-load switch insulating cylinder body, the whole height of this insulating cylinder body is lower, small volume, be conducive to transport and install, being also conducive to the miniaturization promoting circuit breaker loading switch cabinet or on-load switch combined electrical apparatus cabinet simultaneously.
For solving the problem, take following technical scheme:
On-load switch insulating cylinder body of the present utility model comprises body, and body has inner chamber, and it is made up of insulating material.The upper end of described body is opening-like, has vertical through holes bottom it, the intracavity inter-connection of this vertical through holes and body.A sidewall of described body has wire outlet seat, and wire outlet seat has cross through hole, the intracavity inter-connection of this cross through hole and body.Have baffle plate between the sidewall at described vertical through holes and cross through hole place, baffle plate is connected in one with body.Be characterized in the inner body wall that described cross through hole is relative, the baffle plate one side equal undulate from top to bottom that cross through hole is relative, make the equal indention of cross section in this body sidewall, this face of baffle plate.
Wherein, the body sidewall above described wire outlet seat there is observation panel.
Take such scheme, have the following advantages:
Due to the relative baffle plate one side of the relative inner body wall of the cross through hole of on-load switch insulating cylinder body of the present utility model, cross through hole equal undulate from top to bottom, make the equal indention of cross section in this body sidewall, this face of baffle plate.Therefore, their corresponding height obviously will be greater than from bottom to top along the travel distance in this body sidewall, this face of baffle plate, namely only the wave length of this body sidewall from upper end to combined floodgate tie point, the top-down wave Design of length of baffle plate need be become be greater than 210mm, just can meet the requirement being greater than 210mm in national standard about creepage distance.The utility model adopts corrugated creepage structure to instead of the creepage structure of prior art midplane, greatly can reduce whole height and the volume of insulating cylinder body, is convenient to transport and installs.Meanwhile, the reduction of insulating cylinder body height and submission, can also reduce height and the volume of circuit breaker loading switch cabinet or on-load switch combined electrical apparatus cabinet, is conducive to the development promoting this kind of cabinet miniaturization.
Accompanying drawing explanation
Fig. 1 is the structural representation of on-load switch insulating cylinder body of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, on-load switch insulating cylinder body of the present utility model comprises body 1, and body 1 has inner chamber, and it is made up of insulating material.The upper end of described body 1 is opening-like, has vertical through holes 2 bottom it, the intracavity inter-connection of this vertical through holes 2 and body 1.A sidewall of described body 1 has wire outlet seat 4, and wire outlet seat 4 has cross through hole 3, the intracavity inter-connection of this cross through hole 3 and body 1.Have baffle plate 6 between the sidewall at described vertical through holes 2 and cross through hole 3 place, baffle plate 6 is connected in one with body 1.The baffle plate 6 one side equal undulate from top to bottom that body 1 inwall that described cross through hole 3 is relative, cross through hole 3 are relative, makes the equal indention of cross section in this body 1 sidewall, this face of baffle plate 6.
Wherein, body 1 sidewall above described wire outlet seat 4 there is observation panel 5.
