Gang electric - and houndreds types product as like GCK low-

An overview of the
Houndreds types product as like GCK low-voltage withdrawable switchgear is suitable for three-phase ac 50, 60 hz, rated voltage 660 v and rated current under 4000 a and three phase four wire system and five wire three-phase power system, for the use of power and distribution of electrical energy.Widely used in power plants, substations, industrial enterprises and high-rise building power distribution center PC and MCC motor control center.

Conform to the standard
This product conforms to the:
National standard 1, 387251-2005 "low-voltage complete switch equipment";
National professional standard ZBK36001 "" low voltage draw-out switchgear, JBfr9661-1, 999
The international standard lEC439-1 "low-voltage complete switch equipment and control equipment".

Normal conditions of use
1, ambient air temperature is not higher than + 40 ℃.No less than a 1 5 ℃;And its average temperature is not higher than + 35 within 24 hours℃。
2, the surrounding air relative humidity at the highest temperature is + 40℃No more than 50% at low temperature and allow a larger relative humidity.Such as + 20℃ whenIs 90%., but should be considered due to the change of temperature is likely to be accidental to produce a moderate amount of condensation.
3, indoor use, the use of site shall not exceed 2000 m altitude.
4, shall be installed in no violent vibration and impact, and not enough to use electric components from corrosion.

Structural characteristics of
1, the switchgear assembled modular structure is used in the basic frame of the steel by the bolt fastening connection each other into the basic frame, the need to change again according to the plan, combined with the corresponding door, sealing plate, isolation
Board, the mounting bracket and busbar, functional units and other parts assembled into a complete switch cabinet, enclosure structure after galvanizing processing, and implement modular installation (modulus E = 25 RNM), open
Close the tank panel is made of high quality cold-rolled steel plate after forming on CNC machining surface after pickling, phosphating, electrostatic pensu anti-wear corrosion, both strong mechanical strength, and reliable
Grounding continuity.
Compartment can be divided into functional units 2, switchgear rooms, bus room, the cable room, the function of each unit function relatively independent and area between separated strictly by continuous earthing metal plate, ensure that use
Safety and accident prevention.
3 200 RNM, MCC cabinet drawer, 400 mm, 600 RNM three kinds of specifications.Drawer has the connection position, test position and separation position.Each drawer and switch is equipped with mechanical interlock;
When the switch is breaking, the drawer can be pulled out or insert;When the switch in the switching.Can't take out or insert drawer.In order to prevent unauthorised operation, the operator can use the padlock will be open
Lock on the breaking position.Same specification Itill: swap unit drawer can easily.Each function unit drawer to have 20 to auxiliary contacts, can satisfy the different operation control, electricity
Degree of measurement and the needs of the automatic monitoring system for computer interface.

Install and use
1, the installation of the product shall be carried out according to the general installation methods of the power distribution equipment, channel steel and using bolted bolt by the user should bring along their own way.Mistress line connection, it is necessary to make the lap surface
Laminating, level off, or loosen the spell ark bolt to adjust.
2, the product should be check before put into operation after installation and test, check the cabinet surface cover materials such as plastic spraying has damaged, whether contained in the dry, clean and tidy;To check whether there is foreign body inside
(e.g., bolts, welding electrode), each screw fastening the presence of loose, tighten the leakage;Check whether the operating mechanism is flexible, drawer thrusting presence of collision jam phenomenon, agency chain is reliable, action is
No accurate;Check the switch setting current value, instrument calibration, transformer ratio and polarity is in line with the requirements.With 1, 000 finally measured by megger insulation Yang value, should be not less than 1 megohm
Temporary power supply hours.then.Electric points, indexes should be accurate.
3, should maintain daily maintenance operation, regular observation of busbar of fever, found that high temperature or when there is abnormal sound should find out the reason.Depending on the operating environment factors, into every 2 to 5 years
Line a cleanup and maintenance work.
4, use notice:
A series and houndreds types product as like GCK ark for wide wall installation, positive action, double-sided maintenance of low-voltage distribution cabinet.Tank maintenance access and assessment of cupboard door must be qualified professionals can enter or open
For operation, inspection and maintenance;
B, air circuit breaker, molded case switches after multiple points, close, especially after a short circuit points and will then contact the local burn and produce carbon material, and contact resistance increases, should press
Breaker operating instructions for maintenance and repair;
C, after installation or repair, must strictly check each compartment, the condition of isolation between functional units have been restored, good function space, to ensure that the unit to prevent it
Barrier to expand.
