Description

technical field [0001] The invention relates to electric power supply technology, in particular to a multifunctional cabinet protection device. Background technique [0002] In the process of overhauling and maintaining power equipment or cable lines, it is necessary to ensure that the power equipment or cable lines are reliably grounded to prevent the danger to the human body caused by the dangerous voltage generated by a sudden call or the induced voltage generated by adjacent lines. Therefore, it is a very important electrical safety measure to ground the electrical equipment or cable lines through the grounding wire.

Problems solved by technology

The existing low-voltage grounding equipment mainly has two types: clamp type and duckbill type. However, since there is no place for installing grounding equipment at the outlet switch of the low-voltage distribution box, and there are many branches of the low-voltage outlet line, the distance between adjacent low-voltage switches is small. As a result, the grounding equipment cannot be directly grounded in the low-voltage distribution box. In order to ensure emergency repairs, sometimes only the busbars can be grounded. The disadvantage of this is that it will expand the scope of power outages, and it is also prone to safety faults such as grounding short circuits.

[0003] In addition, due to the rapid growth of power consumption, concentrated load, and large peak-to-valley difference, the cable power supply network is under great power supply pressure during the peak load period, especially the distribution box, ring network switchgear, At the outlet switches of power supply equipment such as cable branch boxes and prefabricated substations, the excessive load will cause the current to exceed the standard, the temperature rise will be too large, and the cable will be burned and the equipment will be damaged. Therefore, the current and temperature of the cable power supply network must be monitored. , analyze the law of electricity load through monitoring data

At present, many old cable power supply networks are not equipped with automatic detection equipment, mainly through manual fixed-point measurement. The entire power supply network needs to be replaced, which is very costly and impractical
