ZGS11, ZGS13 -type American box substation

Combined substation, commonly known as American box substation, has excellent performance such as reliable power supply, reasonable structure, rapid installation, flexible, convenient operation, small volume, etc. It is widely used in industrial parks, residential communities, commercial centers, urban roads, high -rise buildings, etc. Plant. This type of product is different from the European -style box substation currently produced in China: American box substation are designed in an integrated design, placement in the same mailbox, and there are small volumes in the same mailbox.

Environmental conditions

Environmental temperature: maximum temperature+40 degrees Celsius, minimum temperature -30 degrees Celsius

The surround temperature: the average daily value is greater than 95%, and the average monthly average is not more than 95%

Altitude ≤ 3000M

Anti -earthquake: Earthquake intensity does not exceed 8 degrees

The surrounding air should not be corroded. Non -flammable gas water vapor is obviously polluted

Uninterpretable strenuous vibration places

The tilt of the installation location is not greater than 3 degrees

When used under normal environmental conditions exceeding the GB3906, users and universal electrical negotiation

Features

Small volume, compact structure, only about one -third of the European -style box substations of the same capacity.

Fully seal and fully insulated structure, without insulation distance, can ensure life safety.

It can be used for the ring network and the terminal, which is very convenient to convey, which improves the reliability of power supply.

Excellent substation performance: low loss, low noise, low temperature, strong overload capacity, strong resistance to short circuit, and strong impact resistance.

The cable joint can operate the 200A load current, which can be operated as a load switch in emergencies, and has the characteristics of isolation.

The use of dual melting protection is reduced, and the operating cost is reduced. The insertion fuse is dual -sensitive melting (temperature, current)

Choose high-combustion point oil (R-TEMP oil, the burning point is as high as 312 degrees Celsius), which can be placed in the building to eliminate hidden fire hazards.

Adopt Dyn11 connection method and three -phase and five -pillar structure, the advantage is that the voltage quality is high, neutral points
