Abstract
The utility model discloses a 35kV outdoor separate-box gas insulated switchgear which comprises an underframe, a separate-box tank circuit breaker fixed on the top surface of the underframe and a spring mechanism fixed on the bottom surface of the underframe, wherein a current transformer and an external earthing switch are arranged at a vertical output terminal located at the top surface at the left side of the circuit breaker, an insulating ceramic insulator is fixed at the top of the current transformer, and a gas insulated bus is fixed at the top surface at the right side of the circuit breaker. The 35kV outdoor separate-box gas insulated switchgear provided by the utility model has the characteristics of a novel structure, good reliability, flexible layout, a small floor space and low production cost.
Description
Technical field
The utility model relates to a kind of combined electric equipment for the 35kV outdoor substation.
Background technology
Middle press seal enclosed combined electrical apparatus is the first-generation metal confining gas insulated switching installation of developing at these use problems at first.Pressure field outdoor products is unenclosed construction at present, floor space is big, indoor product is switch cubicle and inflation cabinet, and it is big that indoor equipment need be built housing investment, for solving above contradiction, the gas-insulated metal-enclosed formula combined electrical apparatus in the novel open air of innovative design, need not build a house, floor space is little, complete closed, be not subjected to ectocine, dwindle the requirement that floor space is reduced investment outlay again to satisfy the power department requirement.
Summary of the invention
The purpose of this utility model just provides a kind of for the outdoor branch mailbox gas insulated metal enclosed swit chgear of 35kV, for realizing above purpose, technical solution adopted in the utility model is: comprise underframe, be fixed on the branch mailbox potting breaker on the underframe end face and be fixed on spring mechanism on the underframe bottom surface, the vertical output of circuit breaker left side end face is provided with current transformer and external earthed switch, insulated porcelain sleeve is fixedly arranged at the top of current transformer, on the right side end face of circuit breaker gas insulated bus is arranged fixedly.
The utility model adopts the branch mailbox potting breaker, and self-energy arc-extinguishing chamber is joined spring operating mechanism, can increase distribution and press instrument transformer, and lightning arrester is realized protection and the metering of circuit.Therefore the utlity model has novel structure, good reliability, flexible arrangement, floor space is minimum, production cost is low characteristics.
