Description
technical field
The present invention relates to a kind of electric power aid, namely one keeps apart official seal porcelain insulator breaking insulating support.
Background technology
In the prior art, in recent years, along with increasing of electric network reconstruction engineering, the frequent grid switching operation increased frequency of equipment.GW5 type isolating switch is double-column horizontal rotary structure, and two, every pole insulation column, with conduction plug-in strip reversed turning 90 °, forms a level fracture, and 50 °, two V-shaped angles of cut of pillar, are arranged on a base.Can be divided into by earthing mode: earth-free, single ground connection, two ground connection.GW5 type isolating switch belongs to the product of the nineties, insulator porcelain vase is not high-strength ceramic, due to equipment long-time running, grid switching operation increased frequency, cause equipment tired, degree of aging strengthens, easy generation malfunction, shake comparatively large in operation or be subject to larger torsion, also because of long overweight in lead-in wire, insulator porcelain vase is in stress for a long time, there is the iron porcelain joint portion phenomenon of rupture of the sub-porcelain vase of isolation switch insulation, cause wire to discharge to truck transom, there is ground short circuit event of failure, cause equipment or personal injury, cause economic loss etc., there is very big potential safety hazard.
Summary of the invention
The object of the invention is for above-mentioned deficiency and provide one to utilize mechanical support principle, insulating support is installed additional in insulator porcelain vase side, porcelain insulator self gravitation is replaced with support force, solve GW5 type isolating switch and close type of isolation switching manipulation is dumb causes porcelain insulator forced breakage, what cause the problems such as wired earth short circuit keeps apart official seal porcelain insulator breaking insulating support.Fixed installation, on truck transom channel-section steel, is applicable to the use of various GW5 series outdoor disconnector.
Technical solution of the present invention is: one keeps apart official seal porcelain insulator breaking insulating support, (corresponding porcelain vase arranges trapezoidal insulating support quantity to comprise at least one trapezoidal insulating support, it is one group that usual corresponding three-phase three porcelain vases arrange three trapezoidal insulating supports), trapezoidal insulating support lower end is with the jig be connected with isolating switch framework channel-section steel, and trapezoidal insulating support upper end is with the iron guardrail (dihedral or the arc that overlap with isolating switch porcelain vase.Be used for preventing that current-carrying part is stressed to come off); Trapezoidal insulating support correspondence be connected with one with the insulation strut of ground diagonal brace.
Described trapezoidal insulating support is three, corresponding three-phase installation of porcelain insulator.By at least one (one or two or three) insulation drag link serial connection between three trapezoidal insulating supports.
Described jig comprises U-shaped screw rod, is connected to the transverse slat pad on U-shaped screw rod and nut; Transverse slat pad is welded with one section of metal tube be connected with trapezoidal insulating support.
Isolating switch framework is installed fixing gold utensil, anti-porcelain insulator breaking insulating support is fixed on gold utensil, is supported in appropriate location with three insulating bars.This Total Product adopts dielectric resin material to make, and top ironwork makes guardrail, is used for preventing that current-carrying part is stressed to come off.Do simulated experiment after anti-porcelain insulator breaking insulating support making is shaping, situation time fracture in Tie Ci joint portion, isolating switch upper and lower part is done in simulation respectively.1. isolating switch top Tie Ci joint portion fracture stimulation experimental technique is: remove four screws that current-carrying part is connected with insulator porcelain vase, then do drawing isolating switch.After isolating switch deciliter, current-carrying part is separated automatically with insulator porcelain vase, and wire and isolating switch current-carrying part fall into iron guardrail completely, measures current-carrying part and framework distance meets safe distance requirement.2. isolating switch top Tie Ci joint portion fracture stimulation experimental technique is: remove four screws that insulator porcelain vase is connected with base, then do drawing isolating switch.After isolating switch deciliter, insulator porcelain vase is separated automatically with base, and insulator porcelain vase leans against on anti-porcelain insulator breaking insulating support completely, measures current-carrying part with framework apart from meeting safe distance requirement too.
Advantage of the present invention is: 1, replace porcelain insulator self gravitation with support force, solves GW5 type isolating switch well and close type of isolation switching manipulation is dumb causes porcelain insulator forced breakage, causes the problems such as wired earth short circuit.The design can reach obvious support effect, prevents insulator porcelain vase to land, avoids wire ground short circuit event, suppresses wire through the generation of framework ground connection electric discharge event.2, anti-porcelain insulator breaking insulating support is easily processed, and Installation and Debugging are convenient, flexible operation, and storage, convenient transportation, can ensure that site operation personnel's safety, can apply the protection with isolating switch of the same type.
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
