Abstract
A combination switch with two-layer parallelly-arranged current transformers relates to the field of gas-insulated metal-sealed high pressure combination switches and mainly solves the problem caused by big external dimension. The combination switch is that a disconnecting switch, an earthing switch, a current transformer, a breaker, a rapid earthing switch combination body, the current transformers and a sleeve form a standard return circuit unit interval, and the combination switch is characterized in that the current transformers are divided into two groups, installed on a same side of a casing of the breaker and distributed in a vertically parallel mode. The combination switch is compact in structure and convenient to transport, reduces requirements for size of transformer substations, greatly improves space use ratio, enables products to tend to modularization and improves production efficiency.
Description
Technical field:
The utility model relates to gas-insulated metal-enclosed high voltage combined switch (GIS) field, the unit switch that especially a kind of CT bilayer is arranged in parallel.
Background technology:
At present, present stage, gas was for insulation metal closed high voltage combined switch (GIS) structure, it is abbreviated as DS by isolating switch 1(), earthed switch (being abbreviated as ES), current transformer (being abbreviated as CT), circuit breaker 4(is abbreviated as CB), the high speed grounding switch assembly, voltage transformer (being abbreviated as PT) and sleeve pipe 7(are abbreviated as PB) etc. equipment form.As shown in Figure 3, wherein two groups of current transformers (CT) are positioned at circuit breaker (CB) double-side straight-line type layout, and namely the housing of circuit breaker (CB) is provided with two flanges, divide to be positioned at the housing both sides, linearly the type structure.This kind infrastructure cost is higher, and product size and floor space are excessive, causes without access path and can't satisfy the requirement of part transformer station indoor location.
The utility model content:
The unit switch that the utility model provides a kind of CT bilayer to be arranged in parallel, this construction of switch is compact, convenient transportation, reduce for transformer station's dimensional requirement, and space availability ratio improves greatly, and product is tending towards modularization more, improve production efficiency, solved the problem that exists in the existing product.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
The unit switch that a kind of CT bilayer is arranged in parallel, it mainly is made of the circuit units interval of a standard isolating switch, earthed switch, current transformer, circuit breaker, high speed grounding switch assembly, voltage transformer and sleeve pipe, it is characterized in that, totally two groups of described current transformers are installed in position the same side of Shell of circuit breaker and are up and down parallel position relationship layout.
Further, described Shell of circuit breaker has two flanges, the axis parallel of two flanges on homonymy.
The beneficial effects of the utility model are:
In the composition of product and the principle of work and power in unaltered situation, only needing the flange with circuit breaker (CB) housing is that two groups of abutted flanges of homonymy are arranged in parallel by both sides linear pattern tectonic reworking, reduced the height of bus, can improve the stability of product structure, the be arranged in parallel utilization of structure of CT bilayer requires to reduce compared with before-improvement 20% for bulk, space availability ratio is improved greatly, make product more dexterous attractive in appearance, product cost reduces by 10%, improve product competitiveness, no matter aspect transportation, or the product structure aspect is all than original more compact structure, more modularization.
Description of drawings:
Fig. 1 is the utility model front view;
Fig. 2 is the utility model vertical view.
Fig. 3 is the front view of existing product;
Among the figure: 1, isolating switch; 2, earthed switch; 3, current transformer; 4, circuit breaker; 5, high speed grounding switch assembly; 6, voltage transformer; 7, sleeve pipe.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
Such as accompanying drawing 1, shown in Figure 2, the unit switch that this CT bilayer is arranged in parallel is gas-insulating and fully-enclosed unit switch, and it is by isolating switch 1, earthed switch 2, current transformer 3, circuit breaker 4, high speed grounding switch assembly 5, the equipment such as voltage transformer 6 and sleeve pipe 7 form.
The basic principle of its work is that circuit breaker 4 is used for disconnecting when overload to be protected whole circuit; Isolating switch 1 is used for whole equipment and bus are disconnected, and makes things convenient for the inspect and change parts; Earthed switch 2 is used for ground connection with circuit units residual electricity conductance ground, guarantees maintenance safety, and current transformer 3 is used for current parameters and the variation at monitoring circuit interval; Voltage transformer 6 is used for monitoring circuit interval voltage parameter and variation; Sleeve pipe 7 usefulness connect the medium of external circuit; High speed grounding switch assembly 5 comprises that isolating switch 1, earthed switch 2 and high speed grounding switch form, and wherein, high speed grounding switch (being abbreviated as HES) has the earthed switch that closes a kind of special purpose of closing the short circuit current ability.After line-to-ground fault is cut, by the secondary arc current of adjacent working line for the electric forming faulty line, utilize high speed grounding switch to close and close, can eliminate secondary arc current, the quick-speed turning on-off earthed switch guarantees that the circuit automatic reclosing can success again.By the circuit units interval that has formed a standard with upper-part.Gas-insulating and fully-enclosed unit switch (GIS) components and parts circuit connecting relation does not change.
As seen, totally two groups of current transformers 3 are installed in position the same side of circuit breaker 4 and are up and down parallel position relationship layout in Fig. 2.And the measure that will realize above-mentioned purpose is that Shell of circuit breaker is transformed, and makes Shell of circuit breaker have two flanges, the axis parallel of two flanges on homonymy.
The utilization of this kind arrangement, reduced the height of bus, can improve the stability of product structure, the be arranged in parallel utilization of structure of CT bilayer requires to reduce compared with before-improvement 20% for bulk, and space availability ratio is improved greatly, make product more dexterous attractive in appearance, product cost reduces by 10%, improves product competitiveness, no matter aspect transportation, or the product structure aspect is all than original more compact structure, more modularization.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
