What is electrical control system
electric control system
Dynamic reactive power compensation electric control system is generally referred to as the two control circuit of electrical equipment, different equipment has different control loops, and high voltage electrical equipment and low-voltage electrical equipment control mode is not the same.
major function
In order to ensure the equipment operation reliability and security, and need to have many auxiliary electrical equipment for the service, to achieve a combination of a control function of a plurality of electrical components, called the control circuit or the secondary circuit. These devices should have the following functions: (1) automatic control function. The volume of high voltage and large current switchgear is very commonly used operating system to control points, closing, especially when the equipment failure, the need to switch automatically cut off the circuit, a set of automatic control of electrical equipment operation and automatic control of power supply equipment. (2) protection function. Electrical equipment and wiring in the running process will malfunction. The current (or voltage) will exceed the device and circuit allows the work scope and limit, which requires a detection of the fault signal and the equipment and lines were automatically adjust (disconnected, switching etc.) protective equipment. (3) monitoring function. Electricity is invisible to the eyes, a device is charged or power outages, from the appearance can not be resolved, it needs to set up a variety of audio-visual signals, such as light and sound, etc., to a device for electrical monitoring. (4) measuring function. Light and sound signals only qualitatively show equipment working state (power, or power), if want to quantitatively know the operation of electrical equipment, but also need to have a variety of instruments measuring equipment, line measurement of various parameters, such as voltage, current, frequency and power of the size. In equipment operation and monitoring, the traditional operation module, control, electrical appliance, instrument and signal equipment and most of them can be controlled by the computer system and the electronic components are replaced, but in small devices and local local control circuit still has certain application scope. This is the basis for the realization of the microcomputer automatic control circuit.
