low-voltage withdrawable type complete switchgear
Description:
GCS low-voltage withdrawable type complete switchgear (hereinafter referred to as the "switch equipment") is my company to meet the requirements of the design unit and power users design developed in line with the national conditions, with high technical performance indicators and can adapt to power market development needs and can compete with the introduction of existing product low voltage draw-out switchgear.
This product has been widely used by power users. Switchgear is suitable for
power plant, petroleum, chemical, metallurgy, textile, high-rise building, and other industries distribution systems
.
In large power plants, petrochemical systems and other places with high degree of automation and requiring computer interface, it is used as a low-voltage complete power distribution device for power distribution, centralized control of motors, and reactive power compensation in power generation and power supply systems with
three-phase AC frequency of 50(60)Hz
, rated working voltage of
380V(400V), (660V)
and rated current of
4000A or below
.
This product conforms to the standards of GB7251 low voltage switchgear and control equipment, JB/T9661 low voltage draw-off switchgear and IEC439 low voltage switchgear and control equipment.
| The main structural frames adopt 8MF section steel, the structural frames can be assembled or welded There are modular holes in structural frames E=20mm. |
| Each function compartment is fully separated. The compartments are: function unit compartment, bus compartment, cable compartment, the function of each compartment is relatively independent. |
| The horizontal bus was not arranged on top, which makes the cable compartment has both upper and lower outgoing, which solved the problem of no way of upper outgoing |

1. Temperature of ambient air: -5°C~+40 pairs
The average daily temperature shall not be higher than +35°C In case of excess, the capacity shall be reduced according to the actual situation |
| 2. Altitude: 2000m and below. |
| 3 relative humidity: the maximum temperature of +40P is not more than 50%, at a lower temperature allowed to have a large relative humidity: such as +20P is 90%, should take into account the temperature changes may occasionally produce the impact of condensation. |
| 4. The mounting incline shall not exceed, and the whole group of cabinets is relatively flat (in line with GBJ232-82 standard). |
| 5. Switchgear should be installed in places free from severe vibration and shock and not enough to cause undue corrosion of electrical components. |
| Note: users have special requirements, can negotiate with the company to solve them. |
