GCK GCL series low -voltage drawing switchgear
Product description
When the GCK GCL series of low -voltage dumping type switchgears is designed according to the needs of the majority of users, it has advanced structure, beautiful appearance, and high electrical performance. The advantages of high protection level, safe and reliable, convenient maintenance are metallurgical and oil. Chemical and electricity. mechanical. Lighting and other industries such as low -voltage supply system ideal power distribution devices. The country is listed as a recommended product and the ninth batch of energy -saving products.
Structural features
The basic framework of GCK and GCL is a combination of assembly structure. All the structures of the framework are galvanized and plasticized. The screws are tightly connected to the basic framework. Safety brackets and parts such as homeline and electrical components are assembled into a complete control center switchgear. The structure of this switchgear has the following characteristics.
The framework uses alien steel, which is located with corner plates, and the bolt -connected unparalleled welding structure is connected.
The molding size of the parts, the size of the hole, and the modularization of the equipment interval. (Model E = 20mm, the same below)
The internal structural parts are galvanized.
External menstrual phosphate; then spray with electrostatic epoxy powder.
The framework is divided into the bus room, functional unit, and cable rooms: three interconnected intervals, which can prevent accident diffusion and easy to maintain maintenance.
Function unit
Functional unit: feeder unit, electric motor unit, public power unit.
The high -level size of the drawer is 200mm, divided into 1/2 unit, 1 unit, 3/2 unit, 2 units, 5/2 units, 3 units, 3 units six -dimensional series. The rated current of the unit circuit is 630A and below.
Each MCC switchgearcan install up to 9 drawers of 9 or 18 units of 1/2 units.
The door panel of the partition is mechanically chain by the operating mechanism of the main switch with the drawer. When the main switch is located at the position of the gate, the door panel cannot be opened.
The operating agency of the main switch can be locked at the position of the closing or split position with a pry, which can safely perform the maintenance of the electrical equipment.
The functional unit partition is separated by metal partition.
The living doors in the partition are automatically opened and closed with the advancement of the drawer and pulling out of it, so that it cannot be vertically attached to the bus in the partition.
H, the back of the function unit has the main circuit in and out of the line plug, the auxiliary circuit second plug and plug.
The ground plug allows the drawer to protect the continuity of the protection circuit when the separation test is connected.
Mother line system
The A, GCK, and GCL parent line system adopts three -phase and four -line, three -phase and five -line system. The horizontal bus is installed on the top of the switchgear.
The three -phase level bus uses the copper bus, which has high mechanical strength and good heat dissipation.
The vertical bus is closed with carbonate licorice shell.
Environmental conditions
The average temperature of the surrounding air temperature: not less than+40 ° C, not less than -5 ° C.24h does not exceed+35 ° C.
Use unit: indoor
Altitude: 2000M
The relative humidity of the surrounding air: The maximum temperature is not more than 50%when the maximum temperature is+40 ° C. At the lower temperature, there is a large relative temperature: (for example, 90%when+20 ° C) allowed at -25 ° C ~+50 ° C temperature temperature The temperature (not more than 24h) temperature (not more than 24h) under conditions does not exceed+70 ° C in a short period of time.
