Industrial Equipment High Voltage Disconnect Switch For Breaking Loadbuster Electrical Isolator
Product Description:
High voltage disconnect switch is a portable, high-voltage
electrical switch used to isolate electrical circuits for
maintenance and repair purposes. It is typically used in medium to
high voltage power transmission and distribution systems.
The high voltage disconnect switch is designed to be portable and
can be easily transported to the location where it is needed. It is
capable of handling high voltage levels, typically ranging from a
few kilovolts to several hundred kilovolts.
The switch is used to isolate a section of the power system for
maintenance or repair purposes. It has visual indicators that show
whether the switch is open or closed, making it easier for
operators to know the status of the circuit.
The high voltage disconnect switch can be used for a wide range of
applications, including switching and isolating circuits, as well
as for grounding and de-energizing equipment. It is designed with
safety features to protect operators from electrical hazards, such
as insulating materials that prevent accidental contact with live
parts.
The switch is easy to use and requires minimal training to operate.
It has interchangeable blades that can be easily replaced, allowing
for greater flexibility and versatility.

1.The altitude does not exceed 1000m
2.The ambient air temperature: Maximum+ 40'C ;Minimum:General Area -30'C, Paramos -40 C;
3.The wind pressure does not exceed 700Pa.(corresponding to 34m/s wind speed);
4.The earthquake intensity does not exceed 8 degrees;
5.The working situation is without frequent violent vibration;
6.The installation site of ordinary type isolator should be kept away form gas, smoke chemical deposition, salt-spray fog, dust
and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator
7.Pollution-proof type isolator is applies to severe filthy conduction area, however, it shouldn't be any explosive matters and matters causing fire
Safety Risks:
1Electrical shock: High voltage disconnect switches can deliver a potentially lethal
electric shock if they are not handled properly. This can happen if
the switch is not properly isolated before it is opened or if there
is a fault in the equipment.
2Arc flash: When high voltage disconnect switches are opened, an arc flash can
occur, which can release a significant amount of energy in the form
of heat, light, and pressure. This can cause burns, eye damage, and
other injuries.
3Equipment failure: High voltage disconnect switches can fail if they are not properly
maintained or if they are overloaded. This can lead to equipment
damage, electrical fires, and other hazards.
4Environmental hazards: High voltage disconnect switches are often located in outdoor
environments, where they can be exposed to extreme weather
conditions, such as high winds, heavy rain, and lightning strikes.
These conditions can create additional safety risks for personnel
who are operating or maintaining the equipment.
P.S.
To minimize the risks associated with high voltage disconnect
switches, it is important to follow proper safety procedures,
including using appropriate personal protective equipment,
following lockout and tagout procedures, and ensuring that only
qualified and trained personnel are allowed to operate and maintain
the equipment. Regular maintenance and testing of the equipment can
also help to reduce the risk of equipment failure and other
hazards.
Safety Tips:
1.Always wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and flame-resistant clothing.
Before working on the switch, ensure that the power supply is turned off, and the switch is properly grounded.
2.Follow the manufacturer's instructions for operating the switch, and do not attempt to bypass safety features or use the switch for purposes other than its intended use.
3.When working on the switch, use insulated tools and equipment to prevent electric shock.
4.Avoid touching any conductive parts of the switch and keep a safe distance from the switch when it is in operation.
5.Never attempt to repair or modify the switch yourself unless you are a qualified and trained professional.
6.Keep the area around the switch clean and free of debris that may interfere with its operation.
7.Regularly inspect the switch for signs of wear or damage, and replace any damaged or worn parts as soon as possible.
8.Only authorized personnel should be allowed to operate or perform maintenance on the switch.
9.In case of an emergency, follow established emergency procedures and shut off power to the switch immediately.
