Monitoring device for high-voltage cable grounding box

Abstract

The invention discloses a monitoring device for a high-voltage cable grounding box. The monitoring device comprises a temperature sensor and a humidity sensor which are arranged in the cable groundingbox. The temperature sensor and the humidity sensor are respectively connected with a temperature sensor display screen and a humidity sensor display screen through signal lines. The temperature sensor display screen and the humidity sensor display screen are arranged in a monitoring box. The monitoring box is provided with an explosion-proof organic glass observation mirror, and the temperaturesensor display screen and the humidity sensor display screen are opposite to the explosion-proof organic glass observation mirror. According to the monitoring device for the high-voltage cable grounding box, temperature and humidity conditions in the high-voltage cable grounding box can be observed in real time, so that an electric power inspector can timely collect operation temperature, humidityand other data of each component in the high-voltage cable grounding box, an operation and maintenance scheme can quickly made for an electric power operation and maintenance management organizationaccording to the provided data, cable operation defects can be timely eliminated, and normal operation of a power line can be ensured.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a monitoring device for a high-voltage cable grounding box. Background technique [0002] The conductor of the high-voltage power cable is the primary winding, and the cable metal sheath is the secondary winding. When an alternating current is generated in the conductor, the alternating electric field will generate an induced voltage on the cable metal sheath. During the operation of power cables, special attention should be paid to the grounding of the metal sheath. For high-voltage single-core cable systems, an appropriate cable sheath grounding method should be adopted according to the actual situation. In order to avoid the influence of the outside world on the grounding effect, the grounding place of various grounding methods should be grounded by installing a cable grounding box, and professional power operation and maintenance inspection personnel are required to i...

Problems solved by technology

In order to ensure the normal operation of power cables, it is necessary to ensure that the zinc oxide sheath protector is in good condition and effective at all times. The current power system management requires inspectors to regularly inspect the cable grounding box during line inspections. Because the cable grounding box is waterproof, moisture-proof, Dust-proof and other sealing and sufficient space for heat dissipation. The sheath protector is installed in the cable grounding box. At the same time, the cables are in a live state during line inspection. The inspection staff cannot effectively check the internal operating environment of the grounding box and cannot timely understand the grounding box. Internal environmental conditions, such as temperature, humidity, protector effectiveness, etc.

The power operation and maintenance management organization cannot quickly and timely eliminate cable operation defects according to the inspection situation of the inspectors
