[0060] Such as image 3 As shown, the adopted scheme is the ground source heat pump heat exchange method. The number of ground source heat pumps used is determined according to the number of secondary equipment in the substation and the underground environment of the installation site. image 3 The scheme adopted is that the whole station equipment shares two heat pumps, and the forms of the ground energy heat exchange pipelines 12 are horizontal and vertical. The specific implementation method is:
[0061] According to the selected technical scheme and installation depth, the ground energy heat exchange pipeline 12 is buried and the ground source heat pump 11 is installed. The bottom of each equipment screen cabinet 1 is provided with an air conditioner terminal 10. The air conditioner terminal 10 is connected to the ground source heat pump 11 through the heat exchange pipe 13 at the end of the air conditioner. The ground source heat pump 11 is scattered on the heat exchange...

The invention relates to the technical field of transformer substation secondary device arrangement methods, in particular to a transformer substation secondary device arrangement system and method based on a terrestrial heat source temperature control mode. According to the system and the method, a ground surface shallow terrestrial heat source serves as a temperature control heat source of a transformer substation secondary device, heat exchange between a screen cabinet of the transformer substation device and the underground environment through a heat exchange system, and therefore a good constant-temperature environment is provided for running a transformer substation. The temperature control mode of the transformer substation is achieved through the terrestrial heat source, so that the transformer substation secondary device arrangement system and method have the advantages that the temperature control effect is uniform and stable, no or fewer temperature control devices need to be additionally arranged, the temperature control system is high in reliability, the transformer substation secondary device arrangement system and method can be suitable for secondary device arrangement under climatic environments in different regions, energy consumption is low, and temperature control efficiency is high. By means of reasonable arrangement, the problem of the running environment of the transformer substation secondary device can be effectively solved.
Description
technical field [0001] The invention relates to the technical field of substation secondary equipment layout systems and methods, in particular to a substation secondary equipment layout system and method based on geothermal source temperature control. Background technique [0002] The operating environment temperature and heat dissipation of secondary equipment in substations are one of the important factors affecting the safe and reliable operation of equipment. Due to the harsh outdoor operating environment, it usually does not meet the operating requirements of secondary equipment. Therefore, it is necessary to control the operating temperature of the equipment by setting up a special protection chamber, setting up a HVAC system, and installing a tide-removing heating device in the equipment screen cabinet. These methods have the disadvantages of high cost, the reliability of the temperature control system affects the operation of secondary equipment, the heating method ...
