Matters Needing Attention When Buy Gis Switchgear

The gis switchgear refers to the switchgear with nitrogen-based mixed gas as the insulating medium. Since the SF6 gas is replaced by a safe and environmentally friendly mixed gas, it is environmentally friendly, and there is no worry of polluting the atmospheric environment after gas leakage. In recent years, many projects have more and more environmental protection requirements for power systems. The gas-insulated ring main unit launched by our company is in line with this trend. It has been running on the grid for more than 5 years, and its performance so far is stable and efficient. ,Safe and reliable.

So what factors should be paid attention to when purchasing a gis switchgear?

1. The altitude of the project site

Like many electrical products, the gas-insulated ring network cabinet has certain requirements for the operating location. When the altitude exceeds 2,500 meters, the high voltage will affect the performance of electrical components, thereby affecting the stability of the overall power distribution. Therefore, when the project site When it is located at a high altitude, it is necessary to confirm with the manufacturer whether the installation site meets the needs of equipment operation.

2. Ambient temperature

my country has a vast territory and different project locations, and the temperature of gis switchgear during storage or operation is also different. Hot or cold temperatures have an impact on it. The temperature range of the storable gas-insulated environmental cabinets is -40°C to +80°C, while the operating temperature is -25°C to +40°C. When it is determined that the temperature of the project site is still higher or lower than this range, it is necessary to communicate and consult with the manufacturer, or this problem can be solved by additionally constructing a special power distribution room.

3. Keep away from corrosive chemicals and pollution

The outer box of the gas-insulated ring network cabinet has certain corrosion resistance, but it cannot withstand long-term corrosion, so pay attention to avoid such items or pollution sources during the design and installation stages.

In general, the gas-insulated ring network cabinet can adapt to most operating environments, but when there are special circumstances, it is necessary to comprehensively consider and record the environmental conditions, and then communicate with the manufacturer for consultation, and coordinate the commissioning and installation of the product according to the actual environment.
