Overview
The phenomenon of overvoltage in the 3-35KV power supply system is very common, and without preventive measures, incidents such as cable blasting may occur at any time. Accidents such as motor insulation breakdown and PT burning can directly damage circuit components in electrical or electronic devices due to overvoltage. This kind of damage can be roughly divided into the following situations based on its severity: causing equipment and devices to work in chaos for a short period of time;
Distribution Juyou cabinet Causing latent faults, reducing the performance of circuits and components, and shortening their lifespan. Early failure; Causing permanent damage to circuits and components;
Causing safety accidents such as fire and electric shock. Abnormal overvoltage may be external or internal to the equipment device. Its appearance may be regular and periodic, but more often random, making it difficult to accurately grasp it in most cases. A single overvoltage protection measure is difficult to effectively prevent it. In response to this situation, our company has developed and produced multifunctional distribution optimization cabinets/overvoltage suppression cabinets. This device can effectively detect various overvoltage conditions in the system and effectively suppress them.
Model number and its meaning
Use environmental conditions
Use environment: Used in power plants. The 3-35kV power supply system for power supply companies and industrial and mining enterprises can replace PT cabinets, lightning arrester cabinets, etc.
Environmental temperature: Indoor type -15 ℃+60 ℃ Special can achieve an altitude of -30 ℃ -+60 ℃<2000m, special circumstances can reach 4000m. The use environment must not have explosive mixtures such as dust, gas, smoke, etc
Product features
Adopting multi-core technology, independent work of each monitoring unit, clear division of labor, faster and more accurate judgment;
Powerful, with overvoltage suppression, arc monitoring, and elimination of ferromagnetic resonance. Loss of voltage, undervoltage, overvoltage, PT disconnection, grounding fault selection alarm function;
When the single-phase grounding fault is relieved and the three-phase voltage is restored to balance, the impact of capacitor current on PT is suppressed, and the problems of PT burning and fuse melting are reduced
