Abstract

The invention discloses a dry-type transformer with a grounding point contact state detection function. The dry-type transformer comprises a transformer protection box, an inclined top cover, an electric lifting rod and an elastic assembly, wherein the inclined top cover is mounted at the top of the transformer protection box; the bottom wall of the transformer protection box is provided with three groups of electric lifting rods which are arranged in a triangular shape, and the bottom wall of the transformer protection box is provided with a plurality of groups of elastic assemblies which are uniformly arranged; a smoke sensor is installed on the top wall of the transformer protection box, a square threaded barrel is installed on the tops of three sets of electric lifting rods, a sleeve is installed on the inner wall of the square threaded barrel, a dry powder fire extinguisher is installed on the inner wall of the sleeve, and an outlet pipe is installed on the top of the dry powder fire extinguisher. The transformer main body and the bottom plate are telescopically clamped through the micro electric extension rod, the assembly firmness of the transformer main body and the bottom plate is improved, the equipment has the effects of monitoring and extinguishing fire and guiding thunder and lightning, and contact detection can be conducted on the wiring terminal and the grounding assembly in real time.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a dry-type transformer with ground point contact state detection. Background technique [0002] Dry-type transformers have the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, and low noise. They are often used in places with high performance requirements such as fire prevention and explosion protection. When used outdoors, they are easily affected by lightning. When lightning strikes occur, the transformer is prone to excessive instantaneous current and voltage. Therefore, it is self-evident to equip the transformer with the function of guiding lightning. [0003] The defects of existing dry-type transformers are: [0004] 1. The patent document CN113724972A discloses a dry-type transformer, "including a transformer coil and a coil cooling part. The transformer coil includes a first coil and a second...
