Low pressure distribution cabinets are electrical systems consisting of multiple electrical components and appliances, and the main working method of low pressure distribution, protection and control of low pressure cables is through a series of switches, protective elements and sensors. Typically, low-pressure distribution cabinets can be divided into the following sections:
1. Input component: the input component is the power supply access component of the low-voltage distribution cabinet, which includes, inter alia, the input of equipment such as the switchboard, cables, circuit breakers, etc。
2. Main distribution component: the main distribution component is used for the rational distribution of the power to be accessed, for the distribution of electrical energy to the appropriate electrical equipment according to different needs and for the control and protection of each electrical equipment through the corresponding switch equipment。
3. Control component: the control component uses equipment such as controllers, touch screens, etc. To achieve automatic control and operation of electrical equipment, e. G. Automatic switch control, setting of protective parameters, etc。
4. Monitoring component: the monitoring component uses a variety of sensors and detection equipment for real-time monitoring of voltage, current, temperature, etc. Of electrical systems and feedback of data to the control system to achieve automated control and operation of electrical systems。
Low-voltage distribution cabinets, through fine control and protection of electrical equipment, can fully exploit the performance and potential of electrical equipment and guarantee the safe and secure operation of the system. At the same time, smart and efficient management of electricity consumption can be achieved on the basis of reliable assurance of the operation of the power system, thereby significantly improving its efficiency and reliability。
The operating procedures for low-voltage cabinets are as follows:
1. Security check: before starting operations, check whether electrical equipment, tools and the surrounding environment are safe. To ensure that the equipment is well located, the equipment is clearly and easily marked, and there are no visible damage or defects。
2. Turning on the power: opens the power switch on the low-voltage distribution cabinet and selects the circuit needed on the distribution cabinet. In general, power switches may be selected on the basis of the power of the equipment and the load to be controlled。
3. Operation breakers: on the distribution cabinet, press the breaker switch to operate handles and open the required circuits. If there are problems with the circuits, they can be stopped in a timely manner and faults can be checked and addressed。
4. Aligning currents: in the case of circuit work, there is a need to adjust currents in circuits to the actual situation. The currents in the circuit can be monitored by searching for suitable fuses on the distribution cabinet or using current meters on the distribution cabinet。
Complete operation: after the operation has been completed, the breaker handle will have to be shut down before the power switch is shut down. Measures such as interlocking are carried out after it has been determined that all equipment has ceased to function. Please close the distribution cabinet and lock it。
It is important to note that the circuits and metaware inside the distribution cabinets are not opened or altered without permission, nor are they removed or replaced at will. If the distribution cabinets need to be changed or repaired, they should be operated by professionals。
