A system and method for underground arrangement of secondary equipment in shaft type substation

Abstract

The invention relates to the technical field of a substation secondary equipment layout system and method, in particular to a shaft type substation secondary equipment underground layout system and method. In the present invention, a shaft for secondary equipment is provided at the lower part of the primary equipment of the substation, a heat conduction protection layer is provided on the inner wall of the shaft for the secondary equipment, and a wiring sleeve is provided inside the protection layer; extraction guide rails are provided in the shaft of the secondary equipment, and the secondary equipment of the substation The primary equipment of the substation is connected to the secondary equipment of the substation through brackets connected to the extraction guide rail; a shaft closure device is provided at the upper wellhead of the secondary equipment shaft, and monitoring sensors and environmental monitoring devices are also installed in the secondary equipment shaft. There is no need to use external cold and heat sources to maintain a constant temperature in the environment, and the operation is reliable; the operating space of the equipment is relatively independent, and it is not easy to be affected by the external environment and expand the scope of accidents; it can meet the needs of changes in the depth of the constant temperature layer and the addition of new equipment during long-term operation, and is suitable for substations On-site arrangement of secondary equipment.

Description

technical field [0001] The present invention relates to the technical field of a substation secondary equipment layout system and method, in particular to a shaft type substation secondary equipment underground layout system and method, which is a shaft type that utilizes heat exchange in the underground environment to provide equipment with a constant temperature operating environment. A substation secondary equipment underground layout system and method. Background technique [0002] In a substation, the environment in which the secondary equipment is located has a direct impact on its reliable operation. In order to ensure the environmental temperature and humidity conditions, it is necessary to adopt measures such as setting up a protection chamber, a HVAC system, and installing a tide-dispelling heating device. These methods have problems such as high engineering cost and unsatisfactory control effects. As the secondary equipment of the substation is lowered close to t...
