Abstract

The invention relates to the technical field of arrangement systems and methods for transformer substation secondary equipment, in particular to a pipeline-type transformer substation secondary equipment underground arrangement system and method. Secondary equipment pipelines are arranged on the lower part of transformer substation primary equipment; pipeline inlets in the tops of the secondary equipment pipelines are connected with pipeline inlet enclosing devices; extraction guide rails and wiring sleeves are arranged in the secondary equipment pipelines; secondary connecting lines are arranged in the wiring sleeves; transformer substation secondary equipment is connected to the extraction guide rails; the transformer substation primary equipment is connected with the transformer substation secondary equipment through the secondary connecting lines; and monitoring sensors and environment monitoring and ventilating devices are further arranged in the secondary equipment pipelines. A stable running temperature is provided for the transformer substation secondary equipment through an underground constant-temperature environment, and the temperature control effect is not influenced by the reliability of a heating device and the environmental change of a transformer substation. A communicated running space is adopted, so that the heat exchange effect is uniform, and the system has high running stability and high adaptability in different climatic environments and is suitable for in-place arrangement of the transformer substation secondary equipment.

Description

technical field [0001] The present invention relates to the technical field of an arrangement system and method for substation secondary equipment, in particular to an underground arrangement system and method for pipeline-type substation secondary equipment, specifically a pipeline-type secondary equipment arrangement using an underground constant temperature environment method. Background technique [0002] In order to ensure the safe and reliable operation of secondary equipment in substations, it is necessary to provide a temperature-stable operating environment for the equipment through temperature control measures. The existing solutions for substations are usually to set up an independent protection chamber and set up corresponding HVAC, tide driving and heating power supply in the screen cabinet, etc. These methods have high engineering cost, the temperature control effect is affected by the reliability of the control system, and the heating effect is localized.
