Overvoltage suppression system used for building equipment

Abstract

The invention discloses an overvoltage suppression system used for building equipment. The overvoltage suppression system comprises a left fixing lug, a high voltage fuse, an upper connecting end, a right cooling area, a right fixing lug, lower connecting ends, isolation areas, a sealing plate and guide grooves. The left fixing lug is arranged at the left bottom position of a shell. The right fixing lug is arranged at the right bottom position of the shell. A total high voltage fuse is arranged in the middle position of the top part of a filling area. The lower connecting ends are led out of resistors. The middle positions of the two sides of the sealing plate are provided with fixing holes. The guide grooves are arranged in the middle positions of the two sides of the shell. The high voltage fuse, the resistors and the total high voltage fuse are connected by conductors. The universality and the practicality of the system can be effectively enhanced, the range of application of the system can be effectively extended, the use cost can be reduced, the economy and the maintainability can be increased and the system is convenient for popularization and application.

Description

technical field [0001] The invention relates to the technical field of protection devices in the construction industry, in particular to an overvoltage suppression system for construction equipment. Background technique [0002] In construction equipment, it is necessary to pay attention to the problem of operating overvoltage. Installing an overvoltage suppression system or a large-capacity overvoltage protector can better protect the equipment from damage and prolong the service life of the equipment. The voltage suppression system often cannot meet the working requirements when it is used. If there is no suitable system overvoltage protection system to suppress and protect the electrical equipment, it is easy to cause safety accidents and huge losses. For example, the voltage transformer caused by overvoltage energy impact Saturation, the occurrence of ferromagnetic resonance causes the bursting and damage of the voltage transformer, and the overvoltage and its energy cau...

[0002] In construction equipment, it is necessary to pay attention to the problem of operating overvoltage. Installing an overvoltage suppression system or a large-capacity overvoltage protector can better protect the equipment from damage and prolong the service life of the equipment. The voltage suppression system often cannot meet the working requirements when it is used. If there is no suitable system overvoltage protection system to suppress and protect the electrical equipment, it is easy to cause safety accidents and huge losses. For example, the voltage transformer caused by overvoltage energy impact Saturation, the occurrence of ferromagnetic resonance causes the bursting and damage of the voltage transformer, and the overvoltage and its energy cause damage to the insulation of the equipment, etc.
