Description

Technical Field

[0001] The utility model relates to a small animal-proof blocking device for a cable inlet and outlet hole, belonging to the technical field of power supply equipment. Background Art

[0002] At present, the plugging methods used for the cable inlet and outlet holes in the distribution cabinets, box transformers, station houses, and telecontrol rooms of existing lines include plugging mud plugging method and FCS sealing component plugging method. These two plugging methods generally have the following disadvantages: 1. Poor durability: According to survey data, the plugging mud begins to loosen, collapse, fall off, and crack under long-term operation (about half a year later), and the durability is poor. Small animals can easily enter the cabinet through the collapse or crack of the plugging mud. According to statistics, about 60% of the failures of power box transformers are caused by the entry of small animals. 2. High material cost: For the plugging method using plugging mud, taking the box transformer as an example, each box transformer high-voltage ring network cabinet has 6 cable holes, 2 low-voltage incoming cable holes, and 6 box transformer basic high and low voltage cable inlets and outlets. A box transformer requires about 12kg of plugging mud for plugging. Each kilogram of fireproof mud is sold at 6 yuan. It costs 72 yuan to plug the cable holes of a box transformer, and the material cost is relatively high. For the sealing method using sealing components, taking the Guinan New Line as an example, the FCS sealing components of Beijing Pioneer Kexun Electric Co., Ltd. are used for sealing. This sealing component is only used for partial sealing of the box transformer foundation. It is suitable for installation on the box transformer foundation when the cable is not laid. It is not suitable for the sealing and transformation of old box transformers. The material cost is high. Four sealing components of a box transformer cost 18,000-20,000 yuan, and the sealing of the cabinet still uses sealing mud. The drawbacks of the sealing mud have not been solved. 3. High labor cost: In areas with low ambient temperature, the sealing mud needs to be heated and softened manually before use; in areas with dry environment, the sealing mud that has been stored for a long time needs to be kneaded with water. The cumbersome operation will take up too much skylight time. It takes about 30 minutes to check the cable sealing conditions one by one during the maintenance of power equipment such as box transformers. When encountering poor sealing, it is necessary to strengthen the sealing and eliminate the hidden dangers in time. The work in the "skylight" point is already tight and the task is heavy, which greatly reduces the utilization rate of the skylight and increases the labor risk accordingly. Utility Model Content
