Inspection of connection and connection process of high and low voltage switchgear in Guizhou
The inspection of the quality of the high and low voltage switchgear is mainly divided into two parts. One is the inspection of the wiring procedure of the high and low voltage switchgear, and the other is the inspection of the switchgear connecting process. If all aspects are satisfied, the quality of the high and low voltage switchgear
It is qualified.
The switch cabinet in Guizhou is discussed in the first place. The first is to check the wiring process of the high and low voltage switchgear. First it is to check whether the conductor is reliable and connected. It requires that each terminal only allow one conductor to connect, if necessary, allow two wires to be connected. Meanwhile, the insulated conductor passing through the metal component should have a proper connection.
Measures to protect the wire from damage.
The wiring harness should be wiring again. The wiring harness must be horizontal and vertical, and the transverse length is not greater than 30mm, and the vertical is not greater than 400mm. There should be a fixed point. If the conductor of the AC circuit passes through the metal diaphragm, all phases and zeros of the circuit should be passed through the same hole.
Then the high and low voltage switch cabinet discharging process inspection, the focus is on the bus process quality and check installation quality, no flow marks, busbar surface coating should be uniform, bending at the bus there shall be no crack and more than 1mm of the surface should be no wrinkles, skin, hair, hammer marks, pits
The Guizhou switch cabinet is shared here today.
