Switchgear indicator and operator is mainly used in indoor switchgear with 0.1KV-40.5KV rated voltage.



The control and display device for switchgear is a comprehensive, multifunctional, intelligent and dynamic indicating device for various kinds of 0.1-0.45kV indoor switch cabinet. With simplified panel and well-organized layout, this switchgear accessory provides information about switch status, and it has been utilized in electric power, chemical engineering, railway, mining, metallurgy, cement and other industries. 




1. All the major components are of industrial grade

2. The switchgear operator adopts high-end PIC Microcontroller supplied by microchip Technology Inc.

3. Temperature data at high voltage electrical contacts are transmitted in a wireless way, so this process is safe, reliable and anti-interference

4. As for signal isolation, both discrete input and communication interface adopt optocoupler and switch while 12V relay is adopted for the output. 

5. The software makes use of several leading-edge technologies, such as redundancy, fault tolerance and digital filtering, to ensure its high reliability. So, our control and display device is able to work normally under extreme conditions for a long time.

Q:Is the GIS in the electric power high voltage switch cabinet
High voltage electrical (mainly above 35kV) exposed to the air, common substation circuit breaker, isolating switch, bus, phases, equipment, and equipment between between and so must have a relatively large safety distance. This area is relatively large, but also exposed to the outside of the security risks are more. GIS is a kind of technology, the bus CircuitBreakers isolating switch for high-voltage electric appliances shell pack, seal filled with six sulfur hexafluoride gas, according to the elements of seal, not a whole big box, such as every bus from the outside is a large cylinder etc.. This equipment can be very compact layout, and a sealed shell, but also more secure.High voltage switchgear is only a device installed in a cabinet, and this is generally high voltage 10kV, up to 35kV, and then there is no general high switch cabinet this form. Of course, you can also use GIS technology. But generally speaking, GIS is more than 110kV GIS switch station.You can Baidu image search GIS switch station". You can see that the big cylinder together is the GIS switch equipment, large cylinder which is the bus, circuit breakers and other equipment, see pictures more intuitive.
Q:What are the effects of frequency variation on power users and power systems?
Influence of frequency variation on power users and power systems:There is a close relationship between the frequency of power equipment and the operation of power system
Q:What is the concentrator of the power set
Although no concentrator can directly meter reading, but reading efficiency, cost and data integrity rate and data sharing will be greatly affected, so the power metersreading general will use concentrators or negative control terminal equipment.
Q:Withstand voltage test, power equipment insulation unqualified reasons?
Without proper consideration of the atmospheric conditions that affect the insulation characteristics. Because of the pressure, temperature and humidity have a certain impact on the spark discharge voltage and breakdown voltage, without considering these factors may lead to equipment failure.
Q:1 what are the main aspects of power line fire? 2 what are the main aspects of electrical equipment fire?
Two, electrical fire monitoring system should be listed in the department or all the monitoring unit:1 electrical fire monitoring equipment;2 residual current type electric fire monitoring detector;3 temperature measuring electric fire monitoring detector;4 linear temperature fire detector
Q:How to strengthen the management of electric power information communication equipment
Problems in the management of information communication equipment1 personnel structure is not reasonable. With the continuous expansion of the power grid, power information communication equipment is also increasing. But at present, there are some problems in the management of electric power communication equipment, such as the lack of professional staff and the lack of post. At the same time, due to the lack of post phenomenon, resulting in the equipment management and maintenance work in the process of increasing the workload, making the existing staff complaints, work quality and work enthusiasm can not be guaranteed. On the other hand, because the new staff less power communication professionals confidence aging trend is more and more serious, the personnel structure imbalance restricts the progress and development of electric power information and communication equipment management to a great extent.
Q:How to handle the qualification test, what kind of power equipment
To submit the application form for the installation of power equipment (repair, test)";
Q:Power transformer equipment bidding procurement are in what units
Power company or Power Grid CorpElectric power company refers to the local responsible for the sale of electricity companies, both widely regarded as the local authority.The Power Grid Corp is a company that is in charge of the construction of the power grid, and belongs to a group, but is a separate company.
Q:Reactive power compensation methods commonly used in power equipment
Hello!Electrical equipment commonly used in reactive power compensation and the method of improving power factor are: synchronous motor, synchro, series capacitor compensation, shunt capacitor and series reactor compensation (EHV transmission line) and SVC, SVG compensation. SVG is through the power electronic device IGBT and its control circuit, a active VaR of equal amplitude and opposite to the size of the system, the reactive power compensation device for reactive power compensation to offset the system in recent years is the development direction of reactive power compensation.
Q:When a fault occurs in power system, the circuit breaker tripping device near fault
When a fault occurs in power system, the circuit breaker tripping device near the fault, in order to reduce the power outage, this is the relay protection ().A, selective B, reliability C, sensitivity D, non selectivity
