[0029] This utility model provides, for example Figure 1-4 The low-voltage reactive power compensation device shown includes a compensation cabinet body 1, a support plate 6 installed inside the compensation cabinet body 1, an mounting plate 7 at the top of the support plate 6, a limiting insert shaft 8 installed at one end of the mounting plate 7, a slot 9 opened inside the support plate 6, a limiting slider 10 installed at one end of the mounting plate 7, a cooling groove 12 opened at one end of the compensation cabinet body 1, a cooling box 13 installed on one side of the cooling groove 12, a fan 14 installed inside the cooling box 13, and a vent 17 opened at the end of the compensation cabinet body 1 away from the cooling groove 12.
[0030] In this system, the user installs the required low-voltage reactive power compensation module on the top of the mounting plate 7. When it is necessary to disassemble, install, maintain, or repair the low-voltage reactive power compensation module on the top of the mounting plate 7, the user can open the cabinet door 2 and pull out the mounting plate 7 on the top of the support plate 6, thereby increasing the space for disassembly and maintenance, making it convenient for the user to perform disassembly and maintenance operations. When the mounting plate 7 is pulled, the limiting pin 8 and the limiting slider 10 can limit the movement of the mounting plate 7, increasing the movement stability of the mounting plate 7. At the same time, when this device is in use, the user can turn on the fan 14 inside the cooling box 13 to cool down the low-voltage reactive power compensation module inside the compensation cabinet body 1, thereby increasing the service life of the low-voltage reactive power compensation module.
[0031] One end of the main body 1 of the compensation cabinet is equipped with a door 2, and one end of the door 2 is equipped with a handle 3.
[0032] Users can open the cabinet door 2 by pulling the handle 3, thereby disassembling and maintaining the low-voltage reactive power compensation module inside the main body 1 of the compensation cabinet.
[0033] The main body 1 of the compensation cabinet is equipped with a first lighting lamp 4, and the bottom of the support plate 6 is equipped with a second lighting lamp 5.
[0034] The first lighting lamp 4 and the second lighting lamp 5 are installed inside the main body 1 of the compensation cabinet to facilitate the lighting disassembly and maintenance of the low-voltage reactive power compensation modules at the top of the two sets of mounting plates 7 in poor lighting conditions.
[0035] A limiting groove 11 is provided at the top of the support plate 6.
[0036] The movement of the limiting slider 10 and the limiting insert shaft 8 is limited by the limiting slide groove 11 and the slot 9.
[0037] A filter screen 15 is installed on one side of the fan 14, and a grille 16 is installed at one end of the cooling box 13.
[0038] A filter screen 15 is installed at one end of the fan 14 to prevent external dust from entering the interior of the compensation cabinet body 1 when the fan 14 is cooling the interior of the compensation cabinet body 1, which could damage the low-voltage reactive power compensation module inside the compensation cabinet body 1.
[0039] A grille window 18 is installed inside the vent 17.
[0040] Among them, by installing a grille window 18 at one end of the vent 17, each partition of the grille window 18 is inclined downward, which can prevent rainwater from entering the interior of the compensation cabinet body 1.
[0041] A barrier net 19 is installed on one side of the grille window 18.
[0042] Among them, a barrier net 19 is installed on the inside of the grille window 18. The barrier net 19 can also prevent dust from entering the interior of the compensation cabinet body 1, while not affecting the airflow inside the compensation cabinet body 1.
[0043] Working principle: When using this easy-to-disassemble and maintain low-voltage reactive power compensation device, the user installs the required low-voltage reactive power compensation module on the top of the mounting plate 7. When it is necessary to disassemble, maintain and repair the low-voltage reactive power compensation module on the top of the mounting plate 7, the user can open the box door 2 and pull out the mounting plate 7 on the top of the support plate 6, thereby increasing the space for disassembly and repair, making it convenient for the user to perform disassembly and repair work. When the mounting plate 7 is pulled, the limiting insert shaft 8 and the limiting slider 10 can limit the movement of the mounting plate 7, increasing the stability of the movement of the mounting plate 7.
[0044] In this device, the fan 14 inside the cooling box 13 can be turned on to cool the low-voltage reactive power compensation module inside the compensation cabinet body 1. A filter screen 15 is installed at one end of the fan 14 to prevent external dust from entering the interior of the compensation cabinet body 1 during cooling and thus preventing damage to the low-voltage reactive power compensation module. A grille window 18 is installed at one end of the vent 17. Each partition of the grille window 18 is inclined downwards to prevent rainwater from entering the interior of the compensation cabinet body 1. The barrier net 19 can also prevent dust from entering the interior of the compensation cabinet body 1 without affecting the airflow inside the compensation cabinet body 1, thus increasing the service life of the low-voltage reactive power compensation module.
