Problems solved by technology

Due to the short opening time of the 35kV substation circuit fault given by the relay protection rules, the currently applied relay protection device cannot complete the action of removing the fault within the specified time according to the set value, so the fault leapfrog trip often occurs, resulting in large area power outage
[0003] 2. The existing 35kV substation covers an area of ​​about 4 to 6 mu, and the consumption of such substations is increasing, so the land occupation of electricity has become the main problem
[0005] 4. At present, domestic 35kV substations are generally outdoor equipment. However, my country's medium and low voltage power equipment has poor weather resistance, acid rain and ultraviolet resistance. Natural corrosion often occurs in substation equipment and requires unplanned power outage maintenance, affecting normal power supply.

Abstract

The present invention relates to a surface protecting type integrating transformer station. It contains underframe fixed with underlayer, top level steel frame, around wallboard and top cover, line in / out equipment room, controller room, room with shutter and doors, top cover fixed upper end of top level steel frame; said line in equipment room fixed with two sets of 40.5 kv lead-in switchgear and two sets of main transformer lead-in switchgear; said line out equipment room fixed with two sets of main transformer line out switchgear, two sets of 10 kv capacitor device and eight sets of 12 kv feeder line switchgear; said main transformer room fixed with two main transformers. Said invention is suitable for 50 Hz 40.5 kv electric system agricultural use electric network and large enterprise affiliated same voltage level power terminal unit.

Description

(1) Technical field [0001] The invention relates to a 35kV surface protection type integrated substation, which is suitable for power system 50Hz, 40.5kV agricultural power grids and large enterprises with the same voltage level of power terminal equipment for power receiving, voltage transformation and power distribution. (2) Technical background [0002] 1. 35kV substations are mostly used in agricultural power grids and power terminal equipment owned by some large enterprises for receiving, transforming and distributing electricity. Because the 35kV substation circuit fault opening time given by the relay protection rules is too short, the currently applied relay protection devices cannot complete the action of removing the fault within the specified time according to the set value, so fault skipping trips often occur, causing Large-scale blackouts. [0003] 2. The existing 35kV substations generally cover an area of ​​4 to 6 mu, and the amount of such substations is increasin...
