Product category: Product Center switchgear Series Product Description: modular design, easy assembly, good scalability. Product Description: GCK (L) series draw out switchgear (hereinafter referred to as the switchgear) is used for AC 380V and below, rated frequency of 50 Hz system, as receiving, feeding, reactive power compensation, electric energy and motor centralized control. This product conforms to the national standard gb7251.1-2005 / iec60439-1:1999 "low voltage switchgear and control equipment" and JB / t9661-1999 "low voltage draw out switchgear".   Service conditions: the ambient air temperature is not higher than + 40 ℃, not lower than - 10 ℃, and the average temperature within 24 hours is not higher than + 35 ℃; The relative humidity of the surrounding air should not exceed 50% when the maximum temperature is + 40 ℃. It is allowed to have larger relative humidity when the temperature is lower, such as 90% when the temperature is + 20 ℃. However, it should be considered that moderate condensation may occur occasionally due to the change of temperature; Indoor use, altitude no more than 2000m; It should be installed in a place without severe vibration, impact and corrosive substances; If the above conditions are exceeded, it should be solved by the user and the manufacturer.   Technical parameters: the overall dimensions of GCK (L) are all standard series dimensions; The height is 2200mm, the width includes three specifications of 600, 800 and 1000mm, and the depth includes two specifications of 800mm and 1000mm. The cabinet is orderly arranged, compact in structure and small in floor area. The top of GCK (L) cabinet is equipped with horizontal bus, the bottom of the cabinet is equipped with n-wire and PE wire, the front of the drawer cabinet is the electrical room, and the back of the components is the bus room, with vertical pluggable bus. Two main circuit coupler sockets and one 10A auxiliary circuit contact 6-20 docking plug-in are installed on the back plate of each drawer. Due to the reasonable combination method, the total capacity of 600 mm wide capacitor cabinet can reach 160 kvar, and that of 800 mm wide capacitor cabinet can reach 240 kvar, making full use of the effective space in the cabinet. With advanced design and technology, the drawer unit is easy to operate and has good interchangeability. The height of functional unit chamber is divided into three types: 200 mm, 400 mm and 600 mm. The cumulative effective installation unit height is 1800 mm, and 1 / 2 functional units can be processed according to requirements. The unit cabinet can hold up to 18 1 / 2 unit drawers or one unit drawer. Each functional unit has perfect and reliable operating mechanism, obvious switch on / off, drawer position mark, accurate limit and limited measures to prevent misoperation, so the operation is safe and reliable. Technical performance: in the PC scheme, it can meet the power receiving, bus coupling, feeding and other functions of 4000A and below. The domestic switches can be me, ah, rmw1, CW1, hsw1 and other types. The imported switches can be ABB F, e series, Schneider m, MT, MW, MD series, Siemens 3wn, 3wt and Korean Hyundai HiAN and other types as the main switches, which are easy to operate, safe and reliable. In the MCC scheme, it can meet the functions of 630A and below feed lighting, motor control and power compensation. Domestic CM1, hsw1, rmm1, sm30, imported Schneider ns, NSD series, Siemens 3vf series, abb s series and Korean Hyundai Hib series can be selected as the protection switch. It is easy to operate, safe and reliable. The main switch has instantaneous, short delay, overload and grounding protection. Customers can choose the protection form according to the needs of the system. When using single bus section, the bus tie switch has automatic switching and automatic recovery, automatic switching and non automatic recovery, and manual switching control mode for customers to choose. The motor control circuit has short-circuit instantaneous, overload, undervoltage, loss of voltage and open phase protection. The AC contactor can operate without noise, which has the effect of energy saving. The customer can choose according to the needs of the project. The main technical data of switch cabinet are shown in the table.   Safety protection: in order to improve the safety of operation and maintenance, the switch cabinet can be divided into different compartments according to different schemes, namely horizontal bus area, vertical bus area, functional unit area and cable area. Each area is separated by metal plate or insulating plate to form a closed space structure. When any unit fails, the normal operation of other units will not be affected, which can prevent the accident from expanding.   Each functional unit (drawer) has propulsion mechanism, interlocking mechanism, limit measures, etc. to prevent misoperation. When the drawer is in the connection position and the main circuit switch is connected to the power supply, the door cannot be opened and the drawer cannot be pulled out. On the contrary, if the switch is not in the off state, the drawer cannot be inserted. In order to ensure safety, maintenance personnel can use padlock to lock the switch at the opening position, and four padlocks can be added at the same time, so the operation is safe and reliable.
