What are the types and working principles of electrical lockouts?

The electrical lockout can be used to lock large and medium-sized or interlocking shut-off valve rockers. In addition, it can also be applied to high and low-voltage power distribution cabinets and power distribution cabinets. So, what are the classifications of electrical lockouts? How does it work? Here are some introductions.

Here is the content list:

Types of electrical locks

Electrical lockouts are generally divided into four types: miniature electrical lockouts, large electrical lockouts, universal electrical lockouts, and small electrical lockouts.

Miniature electrical lockout

The miniature electrical lockout is made of high-strength resin for easy locking.

Large electrical lockout

The large push button lockout is made of high-strength resin and is impact-resistant. The stainless-steel serration makes the lock stronger and is suitable for use on more circuit breakers.

Universal electrical lockout

The new type of push button lockout is made of steel, zinc, aluminum alloy, and high-strength nylon material, which is sturdy and durable. The sliding block is designed to be in place at one time and is easy to use. It can be used with a padlock or a steel cable lock. It is representative of a new generation of push button lockouts.

Small electrical lockout

The small plug lockout is made of high-strength resin. The unique shark mouth design teeth are made of stainless steel and are equipped with fixing screws to provide a stronger bite of the circuit breaker handle. It is matched with an adjustable baffle and scales on both sides of the lock. The length of the switching stroke of various circuit breaker handles is provided to effectively control the loosening of the handle to make it safer.

The working principle of the electrical lockout

The circuit breaker generally includes a casing, a component in the casing, and a handle with the end protruding from the surface of the casing. The operator can move the handle up and down to realize the opening and closing of the circuit breaker. During equipment overhaul or maintenance, the circuit breaker needs to be kept in a certain state. To prevent erroneous operation, the prior art adopts a lock to clamp the handle of the circuit breaker to prevent the handle from being moved.

The existing circuit breaker lockout generally includes a base, a cover hinged with the base through a rotating shaft, and a first chuck and a second chuck installed on the base for clamping the handle.

The base and the cover have lock holes and lock holes in corresponding positions. After the first and second chucks clamp the handle of the circuit breaker, the cover is turned over to wrap the base and the two chucks. The lock hole and the lock hole overlap, and the lock is used to pass through the keyhole and the keyhole to lock so that the cover cannot be turned over. Since the cover wraps the base and two chucks, and the bottom surface of the base is close to the surface of the circuit breaker, the handle of the circuit breaker cannot be turned over, which can avoid human error operating. Only the manager can open the cover of the electrical lockout that passes through the keyhole and the keyhole to turn it over. The main problem in the prior art is that the rotation of the adjusting screw is used to drive the second chuck at a slower speed, and the adjusting screw needs to rotate multiple times to make the second chuck close to the first chuck to clamp the handle of the circuit breaker. Therefore, it takes more time to install the electrical lockout.
