What is electrical products?
Electrical cabinet is used to protect the normal work of components, and cabinets are mainly processed by steel and divided into hot-rolled steel plate and cold-rolled steel plate two kinds of materials. Cold-rolled steel plate is more suitable for the manufacture of electrical cabinet because of its soft material. Electrical cabinets are widely used in chemical industry, environmental protection, power system, metallurgical system, nuclear power industry, fire safety monitoring, transportation industry and other fields. The internal structure of electrical cabinet is complex, including distribution control, circuit breaker, fuse and other components, as well as primary circuit and secondary circuit. The primary circuit is responsible for power transmission and control, while the secondary circuit is used for measurement and control data acquisition and display. The design and manufacture of electrical cabinets need to consider the dynamic stability and thermal stability, as well as the influence of temperature rise and arc impact. In addition, the control of electrical cabinets may adopt PLCDCS and other systems for operation and data management. The types of electrical cabinets include power distribution cabinets and control cabinets, in which the power distribution cabinets are responsible for distributing electric energy to various load parts and carrying out power-off protection when the circuit is short-circuited, overloaded and leaked. The types of power distribution cabinets include fixed panel, protective drawer and power lighting power distribution cabinets, etc. Each type has its own specific application scenario and safety level. Generally speaking, the electrical cabinet is not only the equipment to protect the electrical components, but also an important part of the power system to ensure the safe, reliable and efficient operation of the power system.

High/Low Voltage Starter
High and low voltage soft start is a kind of motor starting technology, which aims to realize the starting of motor and mechanical load by means of step-down compensation or frequency conversion, etc. The influence degree of starting current on power grid and protect power grid and mechanical system. This technology is mainly used to adjust the motor speed by changing the output in the situation where speed regulation is needed. Soft starter and frequency converter are two products with different uses. Soft starter is mainly used for motor starting. After the starting process, the soft starting device exits; The frequency converter is used in the place where the working system is needed. It has all the functions of soft starter and can adjust the speed of the motor. Low-voltage soft start is mainly used in non-full-pressure start-up, also known as undervoltage start-up. Compared with hard start (full-voltage start), low-voltage soft start requires starting equipment and impacts on circuits through starting current For example, for AC three-phase large motor, the incoming line current is connected by star connection to realize soft start In addition, the soft starter installed on the right side of the device is not affected by other components, and the distance between the side wall of the control cabinet and other components is ≥ 100mm, which is convenient for heat dissipation. High voltage soft start involves motor start-up with higher voltage level. It consists of a control module, a thyristor module, a high-pressure vacuum bypass and other components Isolating switch. A disconnecting switch is installed in the input power supply part of the starter to allow the motor to start directly with load. It has the overload ability to start when the load is short-circuited and stop with load In addition, the power supply fuse is used to limit the current of the primary power supply to protect the motor from overload and short circuit. The application of soft start technology is not limited to the motor starting process itself, but also includes soft stop, light load energy saving and various protection functions during the motor running process. These functions can be realized by controlling the conduction angle of the three inverted parallel thyristors so that the input voltage of the controlled motor can be changed according to different requirements. Generally speaking, soft start technology improves the operation efficiency and safety of motor and power grid through start-up and protection mechanism.

3. Control: The control of high-voltage frequency converter is generally based on high-high or high-high frequency converter, while the control of low-voltage frequency converter is more flexible and diverse to meet the needs of different application scenarios.
4. Technical characteristics: High voltage inverters have higher technical requirements in design and manufacture because they need to be able to withstand higher voltage and current while ensuring safe and stable operation of the system. In addition, the high voltage inverter is usually isolated by optical fiber to deal with the electromagnetic interference caused by high voltage.

The anti-corrosion performance can be improved and the service life can be prolonged by spraying or galvanizing treatment Stainless steel has good corrosion resistance and oxidation resistance, which is suitable for strong corrosion and beautiful appearance, easy to clean and maintain, but the cost is relatively high Aluminum alloy material has the characteristics of light weight, high strength and good heat dissipation performance, which is suitable for electrical cabinets requiring high heat dissipation performance. However, the corrosion resistance of aluminum alloy is relatively poor, and appropriate anti-corrosion measures should be taken.
Non-metallic materials
Plastics have excellent electrical insulation performance, corrosion resistance and low cost in non-metallic materials. However, the mechanical strength of plastic shell is relatively low, and it is easy to be deformed by heat, so it is not suitable for high temperature or heavy load Glass fiber reinforced plastic (FRP) has the characteristics of light weight, high strength and good corrosion resistance and insulation performance. Its unique glass fiber reinforced structure makes it have high impact resistance and vibration resistance, which is suitable for the manufacture of electrical cabinets under harsh conditions.
