Description

Technical Field

[0001] The utility model relates to the technical field of substation line fault detection equipment, in particular to substation line fault detection equipment with a protection structure. Background Art

[0002] A substation is a device for converting high-voltage electricity into low-voltage electricity, which is usually used in the power systems of urban or industrial areas. Substations are mainly used for the transmission and distribution of electric energy, and can convert electric power from high-voltage transmission lines into low-voltage access to different electricity-consuming fields.

[0003] The intelligent diagnostic device for decentralized grounding faults in substations is an intelligent device for detecting substation line faults. It can monitor the outgoing circuit of the switch cabinet inside the substation in real time. When a single-phase grounding fault occurs, it sends data to the master station. Usually, the device is installed in the main substation for judging and indicating the single-phase grounding fault of the outgoing circuit of the switch cabinet, and is arranged and operated in a supporting manner with the comprehensive protection device on the switch cabinet. It only needs to access the three-phase voltage on the secondary terminal block of the switch cabinet and the secondary signals of the three-phase current of the outgoing line, and the working power supply is taken from the AC of the switch cabinet.

[0004] When the substation line fault detection equipment is working, it will generate a certain amount of heat. If it is not discharged in time, it will cause the internal temperature of the equipment to rise, affecting the operation of the equipment. However, most of the existing fault detection equipment dissipates heat through simple heat dissipation holes. Even if a heat dissipation fan is installed, the position of the heat dissipation fan is fixed, resulting in relatively poor heat dissipation effect of this fault detection equipment, slow heat discharge, and easy occurrence of local overheating, with insufficient protection. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a substation line fault detection equipment with a protection structure, which can effectively improve the heat dissipation effect of the equipment, quickly discharge the internal heat of the equipment, improve the protection of the equipment, and prevent local overheating inside the equipment.
