Description

The metal enclosed gas-insulated flexible combination of column support type high-voltage switch gear

Technical field

The utility model belongs to the high-voltage switch gear technical field, is specifically related to a kind of switch (hereinafter referred to as the high pressure unit switch) of protecting checkout gear that has that cuts off and connect high-tension current.

Technical background

At present; well-known high-voltage switch gear is in series by bus introducing device, lead-in wire, primary cut-out, bus ejector; and install protection such as voltage transformer, current transformer and lightning protection device checkout equipments on the line, cut off and drop into electric current and the switching device of working by circuit breaker.Its insulation mode is divided into two classes, and a class is that the mode by the complete metal confining gas insulate another kind of pillar gas-insulated, oil-insulation.With the switch that complete metal confining gas mode insulate, the circuit breaker volume is bigger, and each position is difficult to decompose, and installation, maintenance, transportation are made troubles, and has increased cost.And pillar gas-insulated, oil-insulation switch, the distance of each equipment room is bigger, causes overall floor space big, is not suitable for being installed in the transformer station in land resource urban district very in short supply.

Summary of the invention

The purpose of this utility model is to provide a kind of volume little, and installation, maintenance is the high pressure unit switch easily.With solve the above transformer station of 110KV floor space big and install, the disadvantage of maintenance, transportation difficulty.

The high pressure unit switch that the utility model proposes adopts the design of pillar switch module, and each module can require according to the difference of power mode to make up, and each module can independently be installed, transports, be overhauled, and has reduced maintenance cost and difficulty.Introduce the position employing with gas isolated column type circuit breaker at bus or cable, the other end is connected with link block, and link block is connected with voltage transformer, current transformer, lightning protection device again.Replace circuit breaker in the original complete metal confining gas insulated switch with column type circuit breaker, play cut-out, drop into the effect of high-tension current.Column type circuit breaker can rely on gas-insulated, has saved the introducing bus device, thereby has reduced total floor space of switch.

This high-voltage switch gear is by the link block of following standard module as combination;

(1) arc control device 1 of circuit breaker, the operating mechanism connector 2 of (2) circuit breaker, (3) isolation/ground connection unit switch 3, (4) high speed grounding switch 4, (5) the electric current mutual inductance 5, (6) cable seal terminal 6, (7) voltage transformer 7, (8) lightning arrester 8 (can be external), (9) commutator 9 (can select to connect voltage transformer or lightning arrester as required), (10) commutator mechanism connector 10, (11) on-site control 11, (12) the operating mechanism cabinet 12 of circuit breaker, (13) are advanced or outlet sleeve pipe 13.Wherein voltage transformer 7, lightning arrester 8, advance or the seal head and the cable end of outlet sleeve pipe 13, connector 10, cable seal terminal 6 all are designed to the form that can plug, be convenient to be connected with the associated components plug, carry out module combinations.Can connect with the mode of plug, realized the module plugization.

The beneficial effects of the utility model:

The compact conformation floor space is little.

The sulfur hexafluoride gas use amount is few, and is therefore also little to the adverse effect of environment.

Because be modularized design, this high-voltage switch gear can change compound mode according to the actual conditions of transformer station with suiting measures to local conditions, has adaptable advantage, can according to user's busbar drawing prepare take up an area of little, in light weight, flexibility is good, indoorly can both be suitable for outward, customer satisfaction system primary cut-out; Insert for overhead transmission line and cable,, only need the bus access module is changed a little just and can be satisfied according to the different requirements that indoor and outdoors inserts; The transportation of this high pressure unit switch must whole Transporting be compared also greatly facility with switch in the past, and installation, maintenance is convenient, safe and reliable to operation.
