Ordering Instructions Our company can design resistance cabinet according to customer's requirements: Is it equipped with grounding transformer? If yes, provide detailed technical parameters of grounding transformer; cabinet material, IP protection grade, outdoor/indoor type, incoming and outgoing line mode and color, etc. Whether the indoor type is a split cabinet (I. e. the grounding transformer is separated from the resistor cabinet), if it is a split cabinet, please confirm whether it is a parallel cabinet. Resistor material, rated voltage, ground current, current time.
Gas chromatography equipment needs to be in a good environment laboratory and after strict calibration to obtain accurate data. After the laboratory equipment is simplified and transplanted to the online equipment in the outdoor harsh environment, the accuracy of the online data is too poor and only repeatability is available for reference. Therefore, it can only provide reference for the change trend of the transformer that has failed, and it cannot achieve early warning, and it is impossible to analyze the operating state of the transformer that works normally.
MSDGA-I on-line monitoring system of gas in transformer oil realizes the fine analysis of transformer oil by gas chromatography, which has the characteristics of accurate measurement, fast analysis and real-time monitoring. The monitoring system is mainly used to measure and analyze the trace fault gas contained in the insulating oil of oil-immersed power equipment, and can capture the potential fault information of transformer equipment in real time to ensure the reliable operation of transformer equipment.
Gallium arsenide (GaAs) optical fiber sensing technology is widely used in high voltage, high noise, high temperature, strong corrosion resistance, corrosion resistance, small size, high reliability and other special environment equipment monitoring
Transformer is one of the key equipment in the power system, and its normal operation is an important guarantee for the safe, reliable, stable and economic operation of the power system. When the power transformer is running, there is an alternating magnetic field around the winding. Due to the effect of electromagnetic induction, there is a parasitic capacitance between the high-voltage winding and the low-voltage winding, between the low-voltage winding and the iron core, and between the iron core and the shell. The live winding will generate a floating potential between the iron core and the winding through the coupling effect of the parasitic capacitance. Due to the unequal distance between the iron core and other metal components and the winding, there is a potential difference, when the potential difference between the two points to be able to break down the insulation between them, it will produce intermittent spark discharge, the transformer oil and solid insulation have adverse effects, it is necessary to connect the iron core and the shell, so that it and the shell and other potential.
The surface of rare earth alloy grounding material is treated by special process, and the surface corrosion product is nanometer level. The corrosion product is small and dense, which prevents harmful ions in the soil from entering the substrate through the corrosion product film to cause further corrosion, and improves the corrosion resistance of the product. The corrosion resistance of rare earth alloy is 6 times that of galvanized steel.
Optical fiber sensing technology is a sensing technology formed with the development of optical fiber and optical fiber communication technology. Due to the characteristics and advantages of wide working range, good linearity, strong anti-interference performance, small size, and high reliability, it is widely used in equipment monitoring in many special environments such as high voltage, large noise, high temperature, and strong corrosion.
The rapid monitoring device for hydrogen in MSDHT transformer oil is a device that integrates a hydrogen sensor and a micro-water sensor. It has all the characteristics of a hydrogen sensor and a micro-water sensor.
Capacitive bushing is the key equipment of power transformer, and the dielectric loss and equivalent capacitance parameter is an important index to measure the insulation condition of capacitive equipment. Through real-time on-line monitoring of leakage current, equivalent capacitance and dielectric loss of capacitive equipment, real-time monitoring of insulation condition of high-voltage electrical equipment can be realized. At the same time, potential faults of capacitive bushing can be found in time by analyzing monitoring data, which provides important data basis for condition-based maintenance and provides strong and reliable guarantee for safe, reliable, stable and economical operation of power system, provide reliable equipment insulation information and scientific maintenance basis for operation and maintenance personnel, so as to reduce accidents, extend maintenance intervals, reduce the number and time of power outage maintenance, and improve equipment utilization and overall economic benefits.

SW-DLZ series products set protection, measurement, control, bus communication as a whole, while providing remote automatic control, on-site direct control, panel indication, signal alarm, operation records, trip alarm records and switch records and other functions. The product is more powerful and provides customers with better choices.
The leakage current on-line monitoring device developed and produced by our company is suitable for 400V TN and TT systems such as power plants, coal, steel, textiles, etc. It can solve the problem of large-scale power loss caused by high-resistance grounding in MCC lines, non-operation of plastic shell switches and thermal relays, resulting in leapfrog tripping after PC.
The insulation monitoring system continuously detects the leakage current of the electricity system, calculates the change of the insulation performance of the electrical system in real time, and accurately alarms when insulation faults occur, effectively reducing equipment damage, personal electric shock and electrical fire accidents due to leakage, and avoiding sudden power outages. Huge economic losses and adverse social effects are caused, and the prevention is truly preventive.
