Structural characteristics
The structure of the cabinet
1. The Corpus of the stationary cabinet GGD2 is made in the form of a universal cabinet, and the frame is partially welded and assembled from cold -deformed steel 8 MF thickness, which has high mechanical strength and good stability. The level of protection of the cabinet, as a rule, is IP30, which makes it possible to effectively prevent the penetration of external objects and the penetration of dust and water vapors.
2. The size of the cabinet usually is 2200 mm in a height, 600 mm in width, 800 mm in depth (or 1000 mm) and other technical characteristics that can be configured in accordance with the actual needs. The case of the case is usually a light gray Ral7035, which can also be changed in accordance with the user requirements.
Internal layout
1. The chip is divided into several compartments, such as the tire collection compartment, the component component compartment and the cable compartment. Each compartment is independent of each other and isolated by metal partitions to ensure electrical safety. In the upper part of the cabinet there is a compartment for prefabricated tires, which is used to install the main and branch tire pipelines; In the middle of the cabinet there is a compartment for electrical components, which is used to install various electrical components, such as automatic circuit breakers, contactors, relay, etc.; The cable in the lower part of the cabinet is a room that is used to connect the input and output cables.
2. When installing the electrical components in the cabinet, a fixed installation method is used, that is, the electrical components are attached directly to the mounting plate of the cabinet using bolts and other fasteners. This installation method has the advantages of reliable installation and high reliability, but when replacing the electrical components, the power is turned off, which leads to this relatively inconvenient.
Operational characteristics
Electric characteristics
1. The rating of the nominal current is 600-1500 A, which can satisfy the needs of various users in electricity. Its rated current of short circuit usually is 15-50 KA, and it has a high ability to short circuit, which allows you to quickly turn off the circuit in case of short circuit and ensure the safety of equipment and personnel.
2. The grounding system of a three-phase five-wire system (TN-S) or a three-phase four-wire system (TN-C-S) is used to ensure safe and reliable operation of the electric system. Electric components of the cabinet correspond to the corresponding national standards and specifications, and also have good electrical characteristics and reliability.
Safety indicators
1. He has perfect safety measures, such as protection against overload, short circuit, grounding, etc. Automatic circuit breakers, fuses and other electrical components in the cabinet can turn off the circuit in a timely manner during overload or short circuits to ensure the safety of equipment and circuits. At the same time, the cabinet is also equipped with a grounding device to ensure the safety of operators.
2. The cabinet is equipped with a door lock and an observation window, and the door lock is equipped with a mechanical or electromagnetic lock that has good anti -iron properties. The winding window is made of transparent material, which allows the operators to be conveniently observed in the operation of equipment in the cabinet.
