Description

Technical Field

[0001] This utility model relates to the field of power distribution room technology, and in particular to a circuit structure of a power distribution room environmental control box. Background Technology

[0002] In a power distribution room, the quality of the environment affects the working condition of electrical equipment. To ensure that electrical equipment can operate in a suitable environment, an environmental control box is usually installed in the power distribution room. This control box is connected to environmental conditioning equipment such as heaters and exhaust fans. These environmental conditioning devices can be used to regulate the temperature and humidity of the power distribution room, keeping it in a suitable working environment.

[0003] In daily power distribution, it is necessary to inspect and repair electrical equipment in the power distribution room that is malfunctioning or abnormal. Currently, this is usually done by staff bringing the equipment into the power distribution room, which requires providing power outlets for the equipment. However, power distribution rooms generally have high electrical safety requirements, and exposed power outlets must be disconnected from the power supply when not in use. The traditional practice is to use power outlets with built-in switches, which staff can turn off when the outlet is not in use. However, there is a possibility that staff may forget to turn off the outlet switch after using it, which does not meet the electrical safety requirements of the power distribution room. Utility Model Content

[0004] The technical problem this invention aims to solve is how to minimize the interruption of power supply to power outlets in power distribution rooms when they are not in use.

[0005] To solve the above-mentioned technical problems, this utility model provides a circuit structure for an environmental control box in a power distribution room, including a power input interface, a main control board, and an environmental control device. The power input interface supplies power to the main control board, and the main control board is electrically connected to the environmental control device. The box also includes a power socket, a lighting lamp, and a lighting switch. The power socket and the lighting lamp are connected in parallel. The power input interface supplies power to the parallel branch containing the power socket and the lighting lamp via the lighting switch.

[0006] Furthermore, the environmental control equipment includes multiple components, such as a heater, infrared lamps, exhaust fans, and rodent repellents.

[0007] Furthermore, an indicator light is connected in series between the main control board and each environmental control device.

[0008] Furthermore, the main control board is electrically connected to multiple control buttons, each control button corresponding to an environmental control device.

[0009] Furthermore, it includes a temperature and humidity sensor, and the main control board is electrically connected to the temperature and humidity sensor.

[0010] Furthermore, it includes a display, and the main control board is electrically connected to the display.

[0011] Furthermore, the power socket is a power socket with a built-in switch.

[0012] Furthermore, it includes a main control switch, and the power input interface specifically supplies power to the main control board via the main control switch.

[0013] This invention offers the following advantages: When electrical equipment in a power distribution room needs maintenance, workers enter the room and turn on the lighting. Since the power socket and lighting are connected in parallel, the power input interface supplies power to both the socket and the lighting via the lighting switch. Therefore, the power socket is simultaneously powered on when the lighting is on, allowing workers to power the equipment for maintenance. After maintenance, when workers leave the room, the lighting is still on, and they will turn off the lighting switch, simultaneously disconnecting the power socket. This uses the lighting to signal workers to disconnect the power socket, preventing power sockets in the power distribution room from remaining powered even when not in use, thus meeting the electrical safety requirements of the power distribution room. Attached Figure Description

[0014] Figure 1 This is a circuit diagram of the circuit structure of the environmental control box in the power distribution room. Detailed Implementation

[0015] The present invention will be further described in detail below with reference to specific embodiments.

[0016] This embodiment provides a circuit structure for a power distribution room environmental control box, such as... Figure 1 As shown, the circuit structure includes an AC220V power input interface, a main control board U1, environmental control equipment, a power socket S1, a lighting lamp L1, a lighting switch K1, a main control switch K2, a temperature and humidity sensor T1, and a display M1. The AC220V power input interface connects to the mains power. The main control board U1 and the main control switch K2 are located inside the environmental control box in the power distribution room. The power socket S1, lighting switch K1, and display M1 are located on the outer casing of the environmental control box in the power distribution room. The environmental control equipment, lighting lamp L1, and temperature and humidity sensor T1 are located inside the power distribution room. The main control board U1 integrates a microcontroller. The power socket S1 is a two- or three-prong double-pole power socket with a built-in switch. There are four environmental control devices: a heater E1, an infrared lamp E2, an exhaust fan E3, and a rodent repeller E4. The rodent repeller E4 uses an ultrasonic transmitter, which emits ultrasonic waves at a frequency of 16-20kHz with an effective range of no less than 30 meters.

[0017] In this embodiment, the power socket S1 and the lighting lamp L1 are connected in parallel. The AC220V power input interface supplies power to the parallel branch containing the power socket S1 and the lighting lamp L1 via the lighting switch K1. The AC220V power input interface also supplies power to the main control board U1 via the main control switch K2. The operator can control the main control board U1 to be powered on or off via the main control switch K2. The main control board U1 is electrically connected to the temperature and humidity sensor T1, the display M1, and four environmental control devices. Specifically, an indicator light D1 is connected in series between the main control board U1 and the heater E1, an indicator light D2 is connected in series between the main control board U1 and the infrared lamp E2, an indicator light D3 is connected in series between the main control board U1 and the exhaust fan E3, and an indicator light D4 is connected in series between the main control board U1 and the rodent repeller E4. Four indicator lights, D1, D2, D3, and D4, are located on the outer casing of the environmental control box in the power distribution room. When the heater E1, infrared lamp E2, exhaust fan E3, or rodent repellent E4 is turned on, the corresponding indicator lights D1, D2, D3, and D4 will light up.

[0018] The main control board U1 has four control buttons connected to it, namely control button A1, control button A2, control button A3 and control button A4. The four control buttons A1, A2, A3 and A4 are located on the outer shell of the environmental control box in the power distribution room. Each control button corresponds to an environmental control device. Specifically: Control button A1 corresponds to heater E1. Operators can input manual on / off or automatic signals to the main control board U1 via control button A1, causing the main control board U1 to control heater E1 to turn on, off, or enter automatic mode; Control button A2 corresponds to infrared lamp E2. Operators can input manual on / off or automatic signals to the main control board U1 via control button A2, causing the main control board U1 to control infrared lamp E2 to turn on, off, or enter automatic mode; Control button A3 corresponds to exhaust fan E3. Operators can input manual on / off or automatic signals to the main control board U1 via control button A3, causing the main control board U1 to control exhaust fan E3 to turn on, off, or enter automatic mode; Control button A4 corresponds to rodent repeller E4. Operators can input manual on / off or automatic signals to the main control board U1 via control button A4, causing the main control board U1 to control rodent repeller E4 to turn on, off, or enter automatic mode. After receiving manual on, manual off, or automatic signals from heater E1, infrared lamp E2, exhaust fan E3, and rodent repeller E4, the main control board U1 will cause the display M1 to show the working status of heater E1, infrared lamp E2, exhaust fan E3, and rodent repeller E4 respectively.

[0019] It should be noted that after the main control board U1 controls the heater E1, infrared lamp E2, exhaust fan E3, and rodent repeller E4 to enter automatic mode, it detects the temperature and humidity data in the power distribution room through the temperature and humidity sensor T1, and then automatically controls the heater E1, infrared lamp E2, exhaust fan E3, and rodent repeller E4 to turn on or off based on the temperature and humidity data, thereby regulating the temperature and humidity of the power distribution room and repelling rodents, so as to maintain the power distribution room in a suitable working environment.

[0020] When maintenance is required on electrical equipment in the power distribution room, workers will enter the room and turn on lighting switch K1 to illuminate light L1. Since power socket S1 and light L1 are connected in parallel, the AC220V power input interface supplies power to the parallel branch containing power socket S1 and light L1 via lighting switch K1. Therefore, when light L1 is on, power socket S1 is simultaneously powered on, allowing workers to use power socket S1 to power the equipment under maintenance. After maintenance, when workers leave the power distribution room, light L1 will remain on, and they will turn off lighting switch K1 to extinguish it. This simultaneously de-energizes power socket S1. In other words, light L1 serves as a signal to workers to de-energize power socket S1, preventing power socket S1 from remaining powered even when not in use, thus meeting the electrical safety requirements of the power distribution room.

[0021] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
