Problems solved by technology
The interior of the cable trench is relatively closed, and the air flow is not good. At the same time, the cable will generate heat during use, and the heat inside the cable trench cannot be dissipated in time. If it encounters an open flame or other reasons, the cable may catch fire
At the same time, the fire inside the cable trench is relatively hidden and cannot be discovered in time, which will cause greater economic losses

The invention relates to an inspection device with a fire extinguishing function for a high-voltage cable trench. The inspection device comprises a guide rail system and an inspection device body. Theguide rail system comprises a left guide rail and a right guide rail which are fixed on the left side wall and the right side wall of the cable trench respectively, and the inspection device is arranged between the left guide rail and the right guide rail in a sliding mode. And a fire extinguishing device is arranged in the inspection device and can perform fire extinguishing operation on a firesource of the cable trench. According to the invention, real-time temperature monitoring can be carried out on the interior of the cable trench, and the inspection device can carry out short-circuit processing on the cable immediately after the cable is on fire and then move to an ignition point to extinguish fire.
Description
technical field [0001] The invention belongs to the technical field of electric facility safety protection, and in particular relates to a patrol inspection device with fire extinguishing function for high-voltage cable trenches and a fire extinguishing method. Background technique [0002] The cable is usually a rope-like cable twisted by several or groups of wires [at least two in each group]. Each group of wires is insulated from each other and is often twisted around a center. Insulated covering, cables are an important part of the power transmission and distribution process. In the process of power transmission and distribution in cities, factories, communities, etc., cables are usually placed inside cable trenches. The cable channel is usually dug downward on the ground and built by masonry according to the design requirements. The side wall of the channel is welded with a load-bearing angle steel frame and grounded as required, and the top is covered with a cover pla...
