Uses for a Bolted Pressure Switch
A bolted pressure switch is a switch utilized in the operation of major power equipment. The purpose of a bolted pressure switch is to shut off a power unit after the electrical cycle is complete and is most commonly the main disconnect for a facility. Therefore, a bolted pressure switch is an important part of the electrical safety system for a facility. A system’s bolted pressure switch is easy to identify by its long operating handle that compresses the operating mechanism spring within the electrical system.
Electrical Power Systems and a Bolted Pressure Switch
A bolted pressure switch is a major component in electrical power systems and runs on an automatic basis. The only manual processes associated with a bolted pressure switch are related to regular testing, maintenance, lubrication and cleaning. Testing of the switch should take place on a regular basis to ensure the system will work properly when needed. Those very familiar with the function and installation of a bolted pressure switch system can provide the best testing and maintenance matrix. On an average, the system should undergo preventative maintenance, including a visual inspection, at least once a year. Thorough cleaning and lubrication should take place every three to five years, based on usage. If a system that includes a bolted pressure switch is not properly maintained, it could result in costly downtime for the facility.
The process that involves a bolted pressure switch is quite straightforward. The electrical circuit breaks when pressure is applied to the bolted pressure switch, which is found in the switchboard. The bolted pressure switch, which is a knife switch, is enacted when high pressure is put on the blade, when the switch is closed. In today’s applications, knife switches use a snap action mechanism, which opens the switch contacts quickly, as well as systems to close the switch properly. These devices in use today are manufactured to greatly reduce potential injury due to accidental current contact or incidental contact with other working metal, electric-conducting parts within the system.
