Product Detail

Description ：

OMR is a ring main unit for the secondary distribution network. RMU(OMR) can be supplied as a 3 or 4-way  standard configurations with additional equipment according to customer specification. OMR can be supplied in 10  different configurations (Such as CVC, CCV, CVV, CFF, CCC, VVV, CCVV etc) suitable for most switching  applications in 12/24 kV distribution networks.  

It is extendable and combined with our own developed technology concept, which is flexible, modular compact  switchgear, they represent a complete solution for 12/24 kV secondary distribution networks. OMR have identical user interfaces. 

OMR is a completely sealed system with a stainless steel tank containing all live parts and switching functions.  A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel  safety and a virtually maintenance-free system. 

The OMR concept offers a choice of either switch-fuse combination or circuit-breaker with relay for protection of  the transformer. OMR can be supplied with an integrated remote control and monitoring unit. This product is in conformity with the standards: IEC62271-200, IEC60420

Generator circuit breakers(GCB) role in gas turbine power plants
Generator circuit breakers(GCB) role in gas turbine power plants
When starting a gas - turbine generator, its rotor must first be accelerated by external means to approximately 60% of the rated speed. Only then does the start - up process become self - sustaining, meaning the turbine can generate enough power to continue the process independently. To achieve this initial acceleration, energy can be supplied by various means, with a static frequency converter (SFC) being a common choice.Generator circuit breakers (GCBs) play a crucial role in this process. The

Bus-Bar Protection
Bus-Bar Protection
When a fault occurs on the bus bars, the entire power supply is interrupted, and all the non - faulty feeders are disconnected. The majority of bus bar faults are single - phase and often temporary in nature. Bus zone faults can occur due to various factors, such as the failure of support insulators, malfunctions in circuit breakers, or foreign objects accidentally falling across the bus bars. To clear a bus fault, all circuits connected to the faulty section must be opened.The most commonly use

Development and Application of a Miniaturized Intelligent Prefabricated Substation
Development and Application of a Miniaturized Intelligent Prefabricated Substation
With the accelerated construction of smart cities, the urban distribution network is constantly being upgraded and renovated, and the construction of overhead line undergrounding projects is also progressing steadily. A large number of 10 kV overhead lines are being replaced by underground cables. Considering the current situation such as limited space on some urban roads and a shortage of equipment installation locations, higher requirements are placed on the volume, structure, and performance

Discussion on the Maintenance Strategies of Substations and Their Optimization Measures
With the continuous growth of electricity demand and the increasing complexity of power systems, the operating environment and load that substation equipment faces are becoming more and more intricate. This has led to higher requirements for maintenance work. The primary objective of maintenance work is to ensure that the equipment operates in good condition through inspection, maintenance, and repair, and to prevent and eliminate potential faults that may affect the power supply. Currently, the
