Main functions
In order to ensure the reliability and safety of the main equipment operation, many auxiliary electrical equipment are required to provide services for it. The combination of several electrical components that can achieve a certain control function is called a control loop or secondary loop. These devices must have the following capabilities:
(1) automatic control function. The volume of high-voltage high-current switchgear is very large. Usually, an operating system is used to control the opening and closing, especially when the equipment fails, the switch needs to automatically cut off the circuit, and there must be a set of automatically controlled electrical operating equipment. Automatic control of power supply equipment.
(2) Protection function. Electrical equipment and lines will fail during operation, and the current (or voltage) will exceed the allowable working range and limit of the equipment and lines. This requires the detection of these fault signals and the automatic adjustment of equipment and line (disconnect, switch, etc.) protection equipment.
(3) monitoring function. The eyes cannot see electricity. Whether the power of the device is turned off or off is indistinguishable from the outside world. This requires setting up various audiovisual signals, such as lights and sounds, for electrical monitoring of major equipment.
(4) measurement function. Light and sound signals can only qualitatively indicate the working state of the equipment (power on or off). If you want to quantitatively understand the working status of electrical equipment, you also need various instruments and measuring equipment to measure various parameters of the circuit, such as voltage, current, frequency and power.
In equipment operation and monitoring, most of the traditional operation components, control equipment, instruments and signals can be replaced by computer control systems and electronic components, but there is still a certain range of applications in small equipment and local control circuits. This is also the basis for the automatic control of the circuit.
