1 Introduction 35kv fuse is a high-voltage electrical equipment used in power systems. It is mainly used to protect the safe and stable operation of power systems. This article will introduce in detail the technical parameters of 35kv fuses, including rated voltage, rated current, rated short-circuit breaking current, rated short-circuit closing current, rated peak withstand current, etc.2023-11-28
Circuit devices used in cities today mainly include circuit contactors, circuit detection devices, circuit protection devices, etc. The common combination of these devices enables the normal operation and stable transmission of power to every household in the current circuit.2023-11-25
As the main protection component of wind power combined transformers, 35kV high-voltage current-limiting fuses are widely used in combined transformers. The operation conditions show that in the early stages of operation of the wind power combined transformer, the high-voltage current-limiting fuse frequently fails, which is one of the main threats to the safe operation of the combined transformer.2023-11-18

Voltage transformer is an important device in the power system, and its main function is to measure and protect the power system. The equipment has been installed and used in excitation systems, measuring instruments, speed regulators and other electrical equipment. Voltage transformers and high voltage fuses are common accidents in power systems. When the high-voltage fuse of the voltage transformer blows, it will have a serious impact on the safety of the voltage transformer and the measurement of electricity bills. The maintenance and replacement of the high-voltage fuse is also troublesome.2023-11-10
01gas protection An important way of transformer protection is gas protection. Gas protection is mainly used to protect the inside of the transformer oil tank and after the oil level drops.2023-11-04
1. Whether it is AC or DC, first switch the multimeter to the corresponding voltage position, first check the voltage of the pile heads on the two fuses, if normal, it means there is no problem with the power supply, and then check the voltage of the pile heads on the two fuses. If the voltage is the same as the upper pile head, there is no problem with the fuse. If the lower pile head detects no voltage, it can be concluded that one fuse is burned or both fuses are burned.2023-10-07
