FW5-10/200 outdoor high-pressure gas production load switchDetailed product description：

FW5-12/200 outdoor high-voltage gas production load switch (hereinafter referred to as load switch) is used for opening and closing load currents in a three-phase system with AC 50Hz and rated voltage of 10kV.
The load switch is installed on a single pole on the column and can be operated with an insulating rod or rope, or with a pole operated mechanism.

The chassis is welded from angle steel and steel plates, and is equipped with a main shaft, supporting bearings, and a release spring seat, as well as a buffer spring. The upper pillar insulator of the chassis is fixed to the arc extinguishing chamber, and the lower pillar insulator is fixed to the switch blade. The operating mechanism is attached to the right side of the chassis and connected to the spindle. There are several connecting arms welded on the spindle, some of which are connected to the switch blade through rod insulators, some compress the opening spring to store energy for opening, and some collide with the buffer spring for positioning during opening.
The arc extinguishing chamber is mainly composed of a wiring socket, a protective tube, a static contact socket, a contact finger, a contact finger spring, a conductive rod, an arc extinguishing head, an arc extinguishing tube nozzle, and a thrust spring, as shown in Figure 57
1. Closing (two-step action)
Firstly, gently pull down the closing handle and rotate the main shaft clockwise. The lever connecting arm drives the lever insulator to make slight contact between the switch blade and the top of the conductive rod. At this point, the circuit has not yet made contact (the main purpose of this action is to reduce the pulling stroke and facilitate the next step of rapid closing. Special attention must be paid during operation).
Then quickly pull down with force, and the main shaft continues to rotate clockwise. The blade clamp is wedged into the concave neck at the top of the conductive rod, and the conductive rod moves rapidly towards the arc extinguishing chamber. When the main shaft rotates to the closing position of the mechanism, the conductive rod is inserted into the static contact finger, and the circuit is connected. Simultaneously, the opening spring and the thrust spring in the arc extinguishing chamber compress and store energy to prepare for the opening.
2. Open the circuit breaker
Pull down the release tab, the mechanism disengages, and the main shaft rotates counterclockwise through the release lever under the action of the release spring. The lever arm drives the lever insulator to move the switch blade. The conductive rod is separated from the static contact finger by the clamping of the blade and the pushing force of the thrust spring, forming an internal fracture. The arc is generated between the arc extinguishing ring and the arc extinguishing ring. As the conductive rod rapidly moves outward, the elongated arc burns in the narrow gap between the arc extinguishing head and the arc extinguishing tube. The arc extinguishing material produces a large amount of gas due to the arc action. The pressure inside the arc extinguishing chamber surges, and then the airflow is rapidly ejected towards the nozzle, forming a strong longitudinal blow that cuts off the arc extinguishing line. At the same time, the switch blade continues to move under the action of the opening spring and its own weight, and finally separates from the conductive rod to form an external fracture, keeping the switch in a clear opening state.
Installation and usage precautions
1. As the load switch undergoes strict adjustment and testing before leaving the factory, in general, it does not need to be disassembled or readjusted internally. Only the screws at various locations need to be checked for looseness.
Before putting into operation, the insulator should be wiped clean and all mechanical rotating parts should be coated with mechanical oil HJ-30
3. The load switch is a single pole clamp type vertically installed with two clamps and four bolts (provided by the user) fixed to the pole through the chassis
4. Perform 5 to 10 no-load opening and closing operations, with no stagnation or jamming of the conductive rod and mechanism, and an external isolation fracture greater than 110mm during opening
When connecting the busbar to the load switch terminal, the bolts should be tightened. At the same time, the load switch should not be subjected to mechanical stress from the busbar.
6. Process the contact surface of the grounding point to expose the metallic luster, ensuring good contact, and connect the grounding wire.
7. Under the condition that the user complies with the transportation, storage, and use rules stipulated by the manufacturer, if the product is damaged or cannot function properly due to poor quality within 18 months from the date of shipment from the manufacturer, the manufacturer shall repair or replace it for the user free of charge.
