GCK

Product details：

Normal conditions of use
1. The ambient air temperature is not higher than +40 degrees; Not less than -15 degrees; And its average temperature within 24 hours is not higher than +35 degrees.
2. The relative humidity of the surrounding air does not exceed 50 % at a maximum temperature of +40 degrees, and at a lower temperature it is allowed to have a higher relative humidity, such as 90 % at +20 degrees, but it should be taken into account that due to changes in temperature It is possible to accidentally produce moderate condensation.
3. For household use, the altitude of the place of use must not exceed 2000m.
4. Should be installed in places where there is no severe vibration and impact and where the electrical components are not enough to be corroded.
Structural characteristics
1. The basic cabinet frame of the Switchgear adopts a combined structure. The steel type is connected by bolts to each other into a basic cabinet frame. According to the needs of the plan, the corresponding doors, seals, partitions, mounting supports and busbars are added. The functional units and other parts are combined into a complete switchgear. The structural parts in the cabinet are all galvanized and modular installation is implemented. The switchboard surface adopts high-quality cold-rolled steel plates and is machined and molded by CNC machine tools. The surface is acid-washed. After phosphating treatment, static electricity is sprayed. It has strong mechanical strength and reliable grounding protection continuity.
2. The Switchgear compartment can be divided into functional unit rooms, bus rooms, cable rooms. The function of each unit is relatively independent and the area is strictly separated by continuously grounded metal plates to ensure safe use and prevent the spread of accidents.
3. MCC cabinet drawer has three specifications of 200mm, 400mm 600mm. The drawer has connection position, test position and separation position. The drawers and switches are equipped with mechanical interlocking devices; When the switch is broken, the drawer can be drawn or inserted; When the switch is closed, the drawer can not be drawn or inserted. To prevent unauthorized operations, the operator can use padlocks to lock the switch at the Breakpoint position. The functional unit drawers of the same specification can be easily exchanged. Each functional unit drawer should have 20 pairs of auxiliary contacts, which can meet the needs of remote operation control, electrical measurement and automated monitoring systems with computer interfaces.
Main technical parameters
Installation and use
1. The installation of the product shall be carried out according to the general installation method of the distribution equipment. The basic tank steel and bolts used for bolt fixation shall be provided by the user. When the main bus is connected, the joint must be fitted and flattened, otherwise release the binder bolt for adjustment.
2. Before the product is installed and put into operation, it is necessary to conduct inspections and tests to check whether the surface cover material of the cabinet is damaged, whether the cabinet is dry and clean; Check whether there is a foreign body placed in the cabinet, and each screw has no loosening or leakage tightening; Check whether the operating mechanism is flexible, whether the drawer is impinging or not, whether the mechanism chain is reliable, and whether the action is ready; Check whether the switch is fixed current value, the instrument scale, the ratio and polarity of the transformer meet the requirements. In the end, the insulation resistance value measured with a 1000 megabyte ometer should not be lower than that of 1zhaoou, and it should be tested with a temporary power supply.
3. After being put into operation, daily maintenance should be maintained. The fever of the bus line should be regularly observed. The cause should be identified when high temperature rise or abnormal sound is found. According to the operating environment, clean up and maintain every 2 to 5 years.
4. Use Note:
A GCK system cabinets are low voltage distribution cabinets that are not mounted against walls, are operated on the front, and are maintained on both sides. The maintenance channel and door of the cabinet must be a qualified professional to enter or open for operation, inspection and maintenance;
B Air circuit breakers, plastic shell switches that pass through multiple points, close, especially after short-circuit points, will cause local burns on the contacts and produce carbon substances, increase the contact resistance, and should be maintained and overhauled according to the circuit breaker usage instructions;
C After installation or repair, the compartments must be strictly inspected and the isolation between the functional units has been restored to ensure that the device is well separated from the function and to prevent failure and expansion.
