Product Description
Henan New Electric Power Co., Ltd deals in the R&D, manufacturing and sales of various medium, high and Low Voltage Transformers and Transformer Accessories. The transformer accessories mainly include Buchholz Relay, Tap Changer, oil level gauge, butterfly valve, Moisture Absorber, pressure reducing valve, Cross Flow Cooling Fan, Bimetal Thermometer, Epoxy Resin Insulator, etc. New and old customers are welcome to purchase and customize.
The standard Buchholz relay detects the gas released in the insulating liquid and indicates the presence of gas when the content exceeds a certain threshold, which means that no signal is generated before the threshold is reached. And the standard Buchholz relay does not collect information about the length of time the gas has accumulated.
The length of time the gas is released in the insulating liquid is an important criterion for evaluating defects. For example, the quantity and composition of the faulty gas depend on the characteristics of the insulating liquid itself and the energy level of the potential failure. Spontaneous and high-energy faults produce a large amount of gas in a short period of time, and the production of a small amount of gas indicates a small and slowly developing fault.
