HGW9-12G 10/15KV New composite silicone outdoor high voltage AC isolation switch
Product Description
HGW9-12G outdoor AC high-voltage disconnect switch is an outdoor single-phase high-voltage electrical equipment. This product has common type, anti-fouling type, new type, silicone rubber pillar type, suitable for three-phase AC power system with voltage below 15kV and frequency of 50Hz, for switching circuits under voltage and no load conditions.
The isolating switch is composed of a chassis (including hot-dip galvanized chassis or stainless steel chassis), porcelain insulators or silicone rubber insulators and conductive parts. The upper end of the knife is equipped with a fixed hook and a self-pinning device for the insulating operating rod to open and close. use. (with stainless steel screws, springs).
Model Description
Product Structural features and working principle
1. This isolating switch is a single-phase structure, and each phase is composed of a base, a ceramic insulating pillar, an inlet and outlet contact, a knife board and other parts.
2. There are compression springs on both sides of the knife plate to adjust the contact pressure, and the upper end is equipped with a fixed pull buckle and a self-locking device connected to it for opening and closing of the insulated hook.
3. This isolating switch is generally inverted, and it can also be installed vertically or inclined.
The disconnect switch opens and closes by using an insulated hook rod, and the insulated hook rod buckles the disconnect switch, pulling the hook to the opening direction. After unlocking the self-locking device, the conductive plate connected to it will rotate to realize the opening action. When closing, the insulating hook rod against the hook of the disconnect switch drives the shaft to rotate, so that the connected conductive plate rotates to the closing position and
the disconnect switch closes.
This type of disconnect switch can be installed on pillars, walls, ceilings, horizontal frames or metal frames, and can also be installed vertically or obliquely, but must assure that the contact knife is turned downward when it is opened.
