K - Single Key Bolt Interlock

Description

The Tapeswitch Single Key Bolt Interlock is a key operated mechanical bolt interlock suitable for the control of electrical switchgear. The standard unit comes with a 16mm diameter bolt of variable length, that is used to control the rotation or movement of operating handles or toggles of electrical switchgear. Many suppliers of switchgear equipment have mounting kits available for Castell interlocks. The lock is manufactured in brass or stainless steel making it ideally suited to use in harsh or corrosive environments.

Operation

The bolt movement is directly controlled by the rotation of the key. The bolt length can be varied to suit the application but the travel of the bolt from extended to retracted is always 19mm. The bolt length should be specified on ordering by quoting the ‘L’ dimension, this being the length of the bolt protruding from the end face with the key in the trapped position and the bolt retracted.

Typical System

The Single Key Bolt Interlock is designed to operate as part of an integrated safety system, controlling the operation of HV/LV switchgear. A typical example is shown below.

System Description

The power supply to the machine is switched on and the access doors to the hazardous area are locked closed. The initial key is trapped in the K Lock whilst the switch is on. To enter the area, the isolator is turned to the ‘off’ position and the key released, locking the isolator off. The key is then inserted into the ‘X Key Exchange Box’ to release a further two keys which are used to open the ‘AI’ access locks on the doors. Whilst these keys are out of the ‘X Box’, the initial power key cannot be removed, ensuring that the power cannot be switched on whilst the access doors are open.

Features

• Robust construction suitable for heavy duty or harsh environments.
