Abstract
The utility model discloses a 126KV compact gas-insulated metal enclosed switchgear. An output end at the upper right of a circuit breaker is provided with a current transformer, an output end at the lower left is connected to a three-position switch I, and the top of the circuit breaker is provided with a spring operating mechanism. The right end of the current transformer is connected to a high speed grounding switch. The top of the high speed grounding switch is provided with a three-position switch II. The top of a voltage transformer is provided with a three-way. The left end of the three-way is connected to the three-position switch II, and the right end is connected to an outlet sleeve via a bus. The 126KV compact gas-insulated metal enclosed switchgear adopts a miniaturized modular structure, and is simple in structure, small in size and high in technical parameters; and the 126KV compact gas-insulated metal enclosed switchgear is equipped with the spring operating mechanism so that the reliability of the switching operation is greatly improved.
Description
Technical field
The utility model relates to a kind of Cubicle Gas-Insulated Switchgear of miniaturization.
Background technology
Along with the development along with China's electric utility, electric power system continues to large electrical network, large unit, superhigh pressure, large capacity direction fast development, 126kV electric pressure enters under urban district and, plateau underground at some, frozen soil, the environmental condition such as coastal, moist and uses, this just requires GIS will adapt to all-environment requirement, and will develop to miniaturization, reduce floor space.
Summary of the invention
The purpose of this utility model has just been to provide a kind of miniaturization gas insulated metal enclosed swit chgear equipment, specifically a kind of 126KV miniaturization gas insulating metal closed type combined electrical apparatus, its technical scheme of taking is: comprise underframe, be located at the top-right outlet casing tube of underframe, and be from left to right fixed on successively the convergence control cabinet on underframe end face, three-station I, circuit breaker, high speed grounding switch, voltage transformer and lightning arrester, circuit breaker is three-phase combined type potting breaker, the upper right output of circuit breaker is provided with current transformer, its lower-left output connects three-station I, the top of circuit breaker is provided with spring operating mechanism, the right-hand member of current transformer connects high speed grounding switch, the top of high speed grounding switch is provided with three-station II, the top of voltage transformer is provided with threeway, the left end of threeway connects three-station II, its right-hand member connects outlet casing tube by bus.
This combined electrical apparatus adopts three-phase combined type structure, by circuit breaker, isolating switch, earthed switch, the elements combinations such as current transformer are enclosed in the metal shell of ground connection, fill using the SF6 gas of certain pressure and formed as dielectric and arc-extinguishing medium, in ensureing insulation distance, the spatial volume of product is dwindled greatly, between each several part element, connected mode is flexible in addition, can arrange the version that changes product according to concrete space, make product compact overall structure, floor space is little, for 110kV electrical network, cut-off and close line load electric current and short circuit current, carry out the contact of power circuit, switch, route protection, control, measure, safety isolation when system adjusting and circuit and overhaul of the equipments.
This combined electrical apparatus adopts miniaturization modular organization, and simple in structure, the little technical parameter of volume is high; Adapted spring operating mechanism, improves the Reliability of Microprocessor of switch greatly, and all conductors are sealed in the metal shell of sealing, are not subject to ectocine, so it is serious or have a place of severe contamination to be specially adapted to salt fog; Due to ground connection and the shielding action of shell, safer to operations staff.
