Description

A substation outdoor terminal box

technical field

The utility model relates to an outdoor terminal box of a substation, which relates to a power system.

Background technique

The internal space of the terminal box is very compact. In order to ensure the internal insulation level in high-humidity areas and ensure the reliable operation of the device, higher requirements are put forward for the moisture-proof and anti-condensation in the box. my country has used automatic heating and dehumidification controllers to prevent condensation in terminal boxes for more than ten years. There are also some problems in regional applications. For example, in the rainy season in the south, sometimes the air humidity inside the terminal box is high, and there is even condensation in the terminal box. The degree of condensation has not been reached, or the condensation sensor has been corroded by dust and gas in the air for a long time, which affects the sensitivity of the sensor, and the condensation controller cannot start the heater in time, resulting in the failure of the condensation controller. threat to security.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is a schematic structural diagram of an outdoor terminal box of a substation according to the present invention.

Detailed ways

As shown in Figure 1, it is an outdoor terminal box of a substation of the utility model, including a cabinet 1 and a cabinet door 12, and the cabinet is provided with a dehumidification circulation dryer 7, a condensation device, a heater 11 and temperature and humidity Monitor 14, said condensation device comprises condensation chamber 8, condensation sensor 9 and condensation controller 10, described dehumidification cycle dryer 7 is connected with condensation chamber 8, heater 11, condensation sensor 9 They are respectively connected with the condensation controller 10 . The humid air in the cabinet 1 is pumped into the condensation chamber 8 through the dehumidification circulation dryer 7 to separate the air from the water vapor in the air, and the water vapor in the cabinet 1 is promptly released by the dehumidification circulation dryer 7 is collected into the condensation chamber 8, and under the control of the condensation controller 10, it gradually condenses into water droplets or ice crystals. Specifically, the temperature and humidity monitor 14 monitors the temperature and humidity. A. When the natural temperature is greater than 20°C, the water vapor gradually condenses into water droplets in the condensation chamber 8, and the water droplets gather to the water drainage window and are discharged out of the cabinet 1; B. When the natural temperature is lower than 20°C, the water vapor gradually condenses into ice crystals in the condensation chamber 8, which is the process of accumulating frost. Every 120 minutes of continuous frost accumulation, the cabinet dehumidifier will automatically defrost for 10 minutes, and discharge it out of the cabinet 1 in the state of liquid water; C. When the humidity in the cabinet 1 is higher than 55%RH, the cabinet The dehumidifier is automatically put into operation; when the humidity is lower than 40%RH, it will automatically stop dehumidification. When the natural temperature is greater than 30°C and the ambient humidity is greater than 80% RH, the amount of water discharged from the humid air in 24 hours is about 50ml-350ml.

A fan 6 connected to a temperature and humidity monitor 14 is also provided in the cabinet 1 , and an air duct 5 is provided on the cabinet. Adding the blower fan 6 and the air passage can further increase the fluidity of the air in the cabinet 1 and achieve the effect of further keeping the inside of the cabinet 1 dry.

The edge of the opening of the cabinet 1 is provided with a ventilating plate 2 , and several grilles 3 are provided on the ventilating plate 2 . The grids 3 are evenly distributed on the ventilation plate 2, and the distance between the adjacent grids 3 is 1-3 cm, which can not only ventilate, but also prevent small animals from entering. A metal mesh (not shown in the figure) is arranged inside the air channel 5 , and a metal mesh 4 is arranged between the grilles 3 , and the metal mesh and the metal mesh 4 are used to prevent small animals from entering.

Above the ventilation panel 2 and above the cabinet 1, a rainproof cover 13 is provided to play a rainproof effect.
