Description

Technical Field

[0001] The utility model relates to the technical field of vacuum power distribution, in particular to a novel circular vacuum power distribution device for mining. Background Art

[0002] Mining flameproof high-voltage vacuum distribution device, which is used in coal mines with explosive dangerous gases (methane mixture), controls the power supply system with nominal voltage of 10KV, rated frequency of 50Hz, and rated current of 50-630A, and has protection functions such as "overload", "short circuit", "leakage", and "insulation monitoring".

[0003] Surface water can easily infiltrate along the cracks in the roof to the mining and production area. In addition, the roof of the substation needs to be anchored after excavation. The anchors cause direct damage to the aquifer above the roof, causing the accumulated water in the aquifer to infiltrate along the anchors to the substation in the panel area, resulting in roof dripping. This causes the air in the substation to become humid. Once moisture enters the equipment, it can easily cause the insulation of the equipment to decrease, causing great harm to the safety, reliability and continuity of the underground power supply equipment. Thus, a high-voltage vacuum distribution device is provided (see patent number: CN201420250141.4 for details), including a high-explosive switch wiring chamber, characterized in that: the high-voltage vacuum distribution device also includes a heating component arranged inside the high-explosive switch wiring chamber; the heating component includes a heater and a power supply connected to the heater.

[0004] However, some existing vacuum power distribution devices have poor sealing when in use, which results in the device being unable to remain in a vacuum environment for a long time, resulting in reduced practicality of the device. At the same time, some vacuum power distribution devices have a more complicated locking mechanism, which results in cumbersome operation during use, and are also larger in size, resulting in unsatisfactory use results. Utility Model Content
