Problems solved by technology

[0002] The existing electrical room (high voltage room and underground cable room) environmental management system has a low level of intelligence, and there is no comprehensive and unified management and intelligent control for the oxygen content and ventilation of the electrical room, especially for the air quality in the area where people enter the electrical room Lack of effective monitoring and treatment. In addition, it is impossible to manage the equipment operating environment more efficiently and quickly. The cost is high, and the problem cannot be solved fundamentally.

Embodiment 1

[0016] Embodiment 1: as Figure 1-Figure 6 As shown, an electric indoor and outdoor circulation control device in a substation includes an internal temperature and humidity sensor and an oxygen content sensor installed indoors and an external temperature sensor installed outdoors. The internal temperature and humidity sensor, oxygen content sensor and external temperature sensor are connected to The controller is also connected with multiple air supply fans and exhaust fans, as well as multiple air supply valves and exhaust air valves. The multiple air supply fans are respectively connected to the room through branch pipes. fan or cable room intake and exhaust fan), and the return air fan is connected to the return air pipeline.

[0017] The controller is also connected with a heater and a silica gel temperature and humidity sensor in the silica gel chamber.

Embodiment 2

[0018] Embodiment 2: A control method for an electrical indoor and outdoor circulation control device in a substation. The method is: collect the temperature and humidity in the electrical room through a temperature and humidity sensor, and when the average humidity of the collected multiple temperature and humidity sensors is greater than or equal to the set threshold When xRH% is less than the average temperature collected outdoors, multiple air supply valves are opened, and the corresponding multi-channel air supply valves are activated for dehumidification.

[0019] A control method for an electrical indoor and outdoor circulation control device in a substation. If the silica gel temperature and humidity sensor detects that the humidity in the silica gel box is greater than the set threshold yRH%, multiple air supply valves are closed, the exhaust air valve is opened, and the exhaust fan and The heater performs heating and dehumidification of the silica gel box.

Embodiment 3

[0024] Embodiment 3: as Figure 4-6 As shown, a dehumidification device for an electrical room in a substation includes a silica gel box 1. The silica gel box 1 is a bar-shaped structure. A plurality of partitions 3 with air holes 2 are arranged in the silica gel box 1 along the length direction. Adjacent partitions 3 A layer of rubber particles 4 is arranged between them. One end of the length direction of the silica gel box 1 is provided with an air intake pipe 5, and the other end is provided with an exhaust pipe 6 connected to the dehumidification box 15 and a heated exhaust pipe 10. The air intake pipe 5 is provided with a solenoid valve. 7. An exhaust fan 8 and a solenoid valve 2 9 are installed on the exhaust pipe 6, and the heating exhaust pipe 10 is connected to the outside world, and a solenoid valve 3 11 and a heating exhaust fan 12 are installed on it, and a heater is installed on the partition 3 13. A filter screen is provided at the end of the intake pipe 5 .

Abstract

The invention discloses an indoor and outdoor circulation control device of an electric room in a transformer substation and a control method thereof. The control device comprises an internal temperature and humidity sensor arranged indoors, an oxygen content sensor installed indoors, an external temperature sensor installed outdoors. The internal temperature and humidity sensor, the oxygen content sensor and the external temperature sensor are connected to the controller connected with a plurality of blowers and exhaust fans and a plurality of air supply valves and exhaust air valves; the plurality of blowers are connected to the indoor space through branch pipelines. According to the invention, the multiple blowers are started by controlling the indoor humidity and oxygen content changesof the electric room, thereby realizing quick drying and air supplying; the dehumidification effect is improved substantially and the oxygen content is stabilized; the automatic dehumidification andoxygen replenishment are realized; the effect is improved; and the management and control are carried out conveniently.

Description
