HGW9 High Voltage Disconnect Switch
1. HGW9 series 3 phase outdoor 10kv 12kv disconnect switch disconnector 630A
1.1 This isolating switch is a single-phase structure, and each phase is composed of a base, an insulating pillar, an inlet and outlet contact, a knife board and other parts.
1.2 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.
1.3 This isolating switch is generally inverted, and it can also be installed vertically or inclined.
2. Conditions
(1) Altitude: no more than 1500m
(2) Maximum wind speed: no more than 35m/s
(3) Ambient temperature: -40℃~+40℃
(4) The thickness of ice coating is not more than: 10mm
(5) Earthquake intensity: 8
(6) Pollution level: Grade IV
3. Executive standards
GB1985-2014 high voltage AC isolating switch and grounding switch
4. Raw materials
Silicone rubber is made of imported high polymer compound rubber, professionally produced
The mold is vulcanized at high temperature.
The contacts and blanks are all made of T2 pure copper hot extrusion, and then processed by high-precision machining. The surface is silver-plated with fine gloss and anti-oxidation treatment, which greatly improves the oxidation resistance of silver-plated copper parts.
The base is stamped and formed by cold-rolled steel plate, and the surface is hot-dip galvanized with anti-rust treatment, high strength and strong corrosion resistance.
The high-strength insulating mandrel is used in the composite pillar insulator, and the crimping process.
5. Purpose
Isolation switches are generally used for switching operations under the condition of voltage and no load. Isolation switches have obvious fractures after opening, so when inspecting and repairing electrical equipment, they should be used as a part of the high-voltage line for electrical isolation from the live body. Kinds of equipment. 6. Patent
Utility model patent Patent number 201520485011.3 isolating switch
