GCS, GCK low voltage switchboard paralleling switchgear equipment is used in power distribution systems in power plants, petroleum, chemical, metallurgy, textiles, high-rise buildings and other industries.
GCS low voltage withdrawable switch cabinet is used in power distribution systems in power plants, petroleum, chemical, metallurgy, textiles, high-rise buildings and other industries. In large-scale power plants, petrochemical systems and other places with a high degree of automation and computer interfaces, as a three-phase alternating current frequency of 50 (60) Hz, rated working voltage is 380V (400), (660), rated current 4000A and below Low-voltage complete set of power distribution equipment used in power distribution, centralized motor control, and reactive power compensation in power generation and power supply systems.
The cabinet frame is made of 8MF type open section steel, and the two sides of the section steel have installation holes with modulus of 20mm and 100mm respectively. The internal installation is flexible and convenient. There are two types of cabinet frame assembly design, fully assembled structure and partial (side cabinet and horizontal cabinet) welded structure for users to choose. The module of drawer layer height is 60mm, divided into four series: 1/2 unit, 1 unit, 2 unit, and 3 unit. The drawers of the same functional unit have good interchangeability, and can be assembled as required by the mixed assembly of withdrawable units and fixed partitioned units. The panel has obvious position signs of opening and closing tests, drawers, etc.
GCK type low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is suitable for control and distribution systems with AC 50(60)HZ and rated working voltage of 660V and below. It is composed of two parts: the power distribution center (PC) cabinet and the motor control center (MCC). As power distribution equipment such as power distribution motor control and lighting.
The switchgear complies with IEC60439-1 "Low-Voltage Switchgear and Control Equipment", GB7251.1-1997 "Low-Voltage Switchgear and Control Equipment", GB/T14048.1-93 "General Provisions for Low-Voltage Switchgear and Control Equipment" and other standards. And it has high breaking capacity, good dynamic and thermal stability, advanced and reasonable structure, flexible electrical scheme, series, strong versatility, arbitrary combination of various scheme units, a single cabinet contains more circuits, and saves floor space , The advantages of high protection level, safety and reliability, convenient maintenance and so on. This product is widely used in power plants, substations, metallurgy, textiles, petrochemicals, factories and mining enterprises, high-rise buildings and other occasions.
1. The ambient air temperature does not exceed 40℃, and the average value measured within 24h does not exceed 35℃, the lowest ambient air temperature is -5℃,
2. The altitude of the installation site does not exceed 2000m
3. The surrounding air is not significantly polluted by dust, smoke, corrosive and soluble gases, steam or salt spray;
4. Atmospheric conditions: The air is clean, and the relative humidity should not exceed 50% when the maximum temperature is +40℃. At a lower temperature, a higher relative humidity is allowed. For example: The relative humidity is 90% at +20°C. However, it should be considered that due to temperature changes, moderate condensation may occasionally occur;
5. When the equipment is installed, the inclination from the vertical does not exceed 5°;
6. The equipment should be installed in a place without severe vibration and impact.
