In the power supply system of our country, the low-voltage distribution system drops the transmission voltage of the power grid to the distribution voltage, and then transmits it to the low-voltage distribution equipment through the distribution line. At present, low-voltage distribution lines often cause voltage loss, overvoltage, overload and short circuit due to a large number of loads. Moreover, due to the short distribution lines and many extension stages, they will also cause the distribution lines to trip over the level and cause great pressure on the distribution system. Therefore, it is necessary to use the "anti-trip" method and system to protect the distribution lines and distribution systems.
SW-DLZ series phase-to-ground short circuit monitoring and protection devices are suitable for 400V TN system, which can solve the problem of large-area power loss caused by PC leapfrog trip caused by non-metallic grounding, plastic shell switch and thermal relay of MCC line.
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.
The fluorescent optical fiber temperature sensing technology used in this system has the advantages of anti-high voltage, no electromagnetic interference, long-term reliability, easy expansion, etc. It can monitor the temperature of box transformer, high-voltage switchgear, ring network cabinet, outdoor and underground cable joints of power generation and power supply system in real time.
Arc accidents have a catastrophic effect on the equipment, causing system paralysis. TVOC-2 can quickly detect the arc, and with the installation of the circuit breaker, can quickly cut off the current, so as to greatly reduce the damage and impact on the system. In addition, the current sensing unit CSU-2 ensure that the arc protection system only™Trip when necessary, eliminating the risk of nuisance tripping.
The system uses photoelectric technology, communication technology, microprocessor technology, digital vibration sensing technology and independent design of low temperature, strong electric field, wet environment operation technology. It can monitor the cable line profile in real time, can find the cable environment profile as soon as possible, prevent the cable from being damaged by external force, and reduce the loss. At the same time, it can also provide a large number of online monitoring data, providing a reliable basis for operators to understand the operation of the cable.
A variety of power supply and control lines in the low-voltage drawer cabinet are arranged in a relatively narrow space, so that the heat is gathered and should not be dissipated, causing the temperature to rise. Excessive temperature will cause the current carrying capacity of the circuit breaker to decrease, which is different from the actual setting value, which is easy to cause the circuit breaker protection trip. The fluorescent optical fiber temperature sensor is a temperature measurement technology based on optical signals. The sensor has no conductor structure, is insulated and resistant to electromagnetic interference, and has a small size and a long life. It is very suitable for direct measurement of hot spots of connectors in this scenario.
MSD900 transformer intelligent management terminal is an automatic terminal equipment for real-time data acquisition and control of transformers. It can collect various data such as current, voltage and temperature of power transformers, record the accumulated running time of transformers, and realize the evaluation of transformer fault life and give diagnostic schemes through intelligent research and judgment of work rise, load rate and failure rate.
This series of comprehensive analyzer is a multi-functional intelligent switch analog comprehensive dynamic indicating device developed and designed for the current development of medium voltage system switch technology, which is mainly used in various indoor switch cabinets with voltage level of 0.1 ~ 40.5KV.
SW-AFD series intelligent wireless fire alarm automatic fire extinguishing device provides real-time, intelligent and stable fire monitoring scheme for power transformation and distribution system. This device can provide users with uninterrupted on-line fire monitoring, real-time monitoring of temperature and smoke change trend in the monitoring area of switch cabinet and box transformer, realize the functions of temperature warning, smoke warning, fire warning and rapid fire extinguishing, and effectively improve the operation reliability of equipment, provide users with new environmentally friendly features, safe and efficient fire protection solutions. SW-AFD series intelligent wireless fire alarm automatic fire extinguishing system can be used in electric power, metallurgy, chemical industry, communication, rail transit, construction and other industries.
The SW-DLZ300 phase-to-ground short-circuit monitoring and protection device is used in combination with a display host (optional), a single phase-to-ground short-circuit protection device and a high-precision zero-sequence current transformer. One display host and multiple single phase-to-ground short-circuit monitoring and protection devices are installed in each low-voltage cabinet to manage multiple outgoing circuits. The display host group is responsible for parameter setting and local display, and RS485 communication mode is used for numerical setting and data display with multiple single-channel short-circuit monitoring and protection devices; the single-channel phase ground short circuit monitoring and protection device is responsible for collecting zero sequence current, zero sequence current calculation, zero sequence current primary and secondary isolation conversion, fixed value setting (parameter setting and fixed value setting can be performed by computer software when there is no display host), protection logic judgment control, trip control outlet and other functions, and has independent communication function with the upper computer, and can be flexibly configured according to the site conditions.
Real-time monitoring: real-time display of the zero-sequence current of the monitored line is helpful for maintenance personnel to accurately judge the insulation status of the system and make maintenance plans.
