Product Description
Product Description
KGH is suitable for AC 50HZ, voltage 1140V, and currents of 200A, 315A, and 400A in power lines. It is used for main circuit isolation and for changing the phase sequence of the power supply under no-load conditions. High breaking power, especially suitable for composing kilovolt mine isolated electromagnetic starter.

Product features and use environment
Features:
1. The arc extinguishing cover is made of DMC arc extinguishing insulating material and is die-cast. With high insulation arc extinguishing. nice appearance.
2. Reliable and stable on-off commutation capability.
3. GHK series isolating reversing switches are equipped with auxiliary contacts, and there are two pairs of auxiliary electric shocks, one normally open and one normally closed, for external circuits.
Use environment:
1. Air temperature -25ºC~+40ºC, the average value within 24h should not exceed 35ºC, please negotiate with our company if it exceeds the range
2. The altitude should not exceed 2000m
3. Ambient air pressure (86 -106) Kpa
4. In an environment free of harmful gases sufficient to damage insulation and corrode metals.
Structure principle and operation maintenance
Structure principle:
The contact assembly is composed of three-phase static contact, forward moving contact group and reverse moving contact group, enclosed arc barrier arc extinguishing shield, insulating arc resistant plastic frame and cover. The silver alloy contact system adopts the single break point snap structure, which is characterized by the double L-shaped backrest symmetrical structure of the static contact, and the magnet is set in the contact circuit to enhance the self-excited magnetic field, so that when breaking large current, a strong electric repulsion force is generated between the static contact and the moving contact arm, which is conducive to improving the breaking speed, blowing the arc magnetic field, and reducing the stagnation time of the arc on the contact, The rising rate of arc voltage is increased to make the arc enter the arc extinguishing grid rapidly, thus greatly improving the arc extinguishing effect when breaking. With the help of operating mechanism and cross conductor, forward and reverse moving contact groups realize the connection, disconnection and phase sequence of power supply replacement of moving and static contacts.
Use, installation and maintenance:
1. Before use, check whether the accessories of the switch are assembled completely and correctly.
2. The switch must be installed vertically before use
3. The operating mechanism shall be flexible during installation and use, and a small amount of lubricating oil can be added to the hinge of each moving part; Regularly check the operation of the contact and measure the closure of the contact.
4. During operation, the working condition of the contact shall be checked regularly. If the contact is found to be singed, it is necessary to timely repair and measure the closing condition of the contact. After each load breaking, the working condition of the contact shall be checked.
