The role of the vacuum outdoor circuit breaker.
1. control role: that is, according to the needs of grid operation, part of the electrical equipment into or out of operation.
2. Protection role: that is, in the event of a fault in electrical equipment or power lines, the relay protection automatic device to issue a tripping signal, start the circuit breaker, the faulty part of the equipment or line from the grid quickly removed to ensure the normal operation of the non-faulty part of the grid
In simple terms, vacuum switches help us to detect, control and monitor the pressure in different equipment systems.
The vacuum switch is used to detect, control and monitor the pressure in different equipment systems. Not only do they help to stop the upper limit, but they also help to start the lower limit, with bi-directional control to achieve more performance requirements. In addition to this, these devices can also help to set up delayed starts so that motor equipment does not suffer from frequent start-ups or airlifts, which can cause different levels of wear and tear. The vacuum switch also has a one-touch clearing function, which in turn makes the various settings completely ineffective. The principle of the vacuum switch is to use the pressure protector in the vacuum system, which detects when the vacuum pressure in the system exceeds a set standard and automatically cuts off the equipment's circuit and issues an alarm. When the device detects that the pressure in the system is below a set standard, a series of actions are taken to stop the equipment.
Applications of vacuum switches
Vacuum switches are widely used in various industrial automation environments, involving petroleum pipelines, water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipeline air supply, boiler negative pressure and many other industries.
The vacuum switch is mainly used in metallurgy, chemical industry, petroleum, steel, machinery, refrigeration equipment, freezing equipment, water pump pressure control, low water level protection pressure, etc.
Pressure control, low water level protection pressure control, power plants, cement, food, ships and other industries of gas, steam and water, oil and other liquid pressure equipment and other industrial equipment in the actuator supporting the pressure monitoring, alarm, interlock protection, to achieve two-position automatic control.
