Safety Is Number One
The incorporation of a key interlock system into the design of an electrostatic precipitator and the establishment of procedures for the use of the installed interlock system provides a measure of safety to personnel by eliminating contact with energized precipitator components and exposure to the radiation from nuclear level probes.
Ideally, the key interlock system must provide the mechanism(s) to prevent contact with the energized components as well as "guide" the user through the interlock system to ensure that equipment is energized or de-energized and access points made accessible or inaccessible in the proper sequence.
Access Door Locks
Access door lock with bolt eye and chain.
The most common device requiring a lock is a door. This is also true for the doors installed on electrostatic precipitators. Access door locks are the most plentiful locks in a precipitator key interlock system. Access door locks are also the locks that...
Key Transfer Blocks
Key transfer blocks provide the mechanism by which access authority is moved from one point in a key interlock system to another. Key transfer blocks generally require that one or several keys must be present before one or more keys can be released. For example, the presence of all transformer-...
Transformer Rectifier and Circuit Breaker Locks
It is apparent when considering the design of an electrostatic precipitator interlock system that the point of energization must be addressed. From one standpoint, access must be allowed to the high voltage sections of the precipitator only when the Transformer-Rectifier has been placed in a...
Key Interlock System Design
The complexity of interlock systems varies from installation to installation. As a rule of thumb, the larger the quantity of transformer-rectifiers and precipitator chambers, the more complex the interlock system can be. The addition of a transformer-rectifier or a precipitator chamber can...
