Problems solved by technology
Because the dark cabinet inside the cabinet is bright outside, in fact, the equipment in the cabinet cannot be seen clearly from the outside of the cabinet to the inside of the cabinet.
In addition, this kind of observation window is made of ordinary glass that cannot penetrate infrared rays, so it cannot be used to detect whether there is a heating defect in the equipment in the cabinet.
If you want to know the operating status of the equipment in the cabinet, you have to open the cabinet door to check when the power is off, which greatly reduces the power supply reliability of the equipment.

Embodiment Construction
[0023] Such as figure 1 , 3 As shown, the switch cabinet door panel 1 is made of metal materials, the handle 2 is installed on the upper part of the door panel 1, the infrared window 3 is installed in the middle of the door panel 1, and the daylighting window 4 and the ventilation valve 5 are installed on the lower part of the door panel 1.
[0024] Such as Figure 4 , 5 As shown in 6, 7, the infrared window 3 is composed of a protective cover 301, an infrared glass 302, a pin hole 303, a rotating shaft 304, a fixing ring 305, and a fixing pin 306. According to the size of the infrared window 3, a hole is opened in the middle of the door panel 1, and the infrared window 3 is put into the hole, and the fixing ring 305 is rotated until the infrared window 3 is fixed on the door panel 1. The rotating shaft 304 of the protective cover 301 is at the lower part of the infrared window 3, and the protective cover 301 can rotate around the rotating shaft 304. The fixing pin 6 is located ...

The invention discloses a switch cabinet door. The switch cabinet door is characterized in that the switch cabinet door is additionally provided with an infrared window, a light-taking window and a ventilation valve, wherein the infrared window is installed in the middle of the switch cabinet door, and the light-taking window and the ventilation valve are embedded into the lower portion of the switch cabinet door. The infrared window of the switch cabinet door allows infrared rays to pass through, so that the heating conditions of devices in a switch cabinet can be detected through a temperature measurement instrument without opening the switch cabinet door. Light is introduced into the switch cabinet through the light-taking window, so that the devices in the cabinet are easily observed. When a condensation phenomenon in the switch cabinet is serious, dry hot air can be blown into the switch cabinet through the ventilation valve, and therefore condensation adhering to the powered-on devices is eliminated.
Description
technical field [0001] The invention relates to power distribution equipment, and more specifically relates to a switch cabinet door. Background technique [0002] 10kV switch cabinets used in outdoor equipment such as 10kV ring network cabinets, cable branch boxes, and European-style box transformers have a rectangular observation window in the upper part of the cabinet door to observe the operating conditions of the equipment in the cabinet. Because the dark cabinet inside the cabinet is bright outside, in fact, the equipment inside the cabinet cannot be seen clearly from the outside of the cabinet to the inside of the cabinet. In addition, this kind of observation window is made of ordinary glass that cannot penetrate infrared rays, so it cannot be used to detect whether there is a heating defect in the equipment in the cabinet. If you want to know the operating status of the equipment in the cabinet, you have to open the cabinet door to check when the power is off, whic...
