Product Details

Overview
This system is composed of naturally cooled high-frequency switching power supply modules. It is divided into two types: integrated system (charging and feeding in one) and split-screen system (charging screen and feeding screen are separated). It is mainly used in power plants, substations, petrochemical, mining, railway and other units. It is suitable for power supply of instruments, meters, relay protection and fault lighting in circuit breaker opening and closing and secondary circuits.
 
Features
● Special modular design of switching power supply and N I hot backup are adopted.
● charging module can be charged plug, greatly shorten the maintenance time.
● The system adopts natural cooling method.
● Using the latest soft switch technology, the key devices are all high quality imported brand-name products.
● Reliable lightning protection measures and high electrical insulation protection measures to ensure system and personal safety.
● The monitoring unit adopts large-screen LCD Chinese character display, sound and light alarm.
● The parameter settings of each part of the system can be modified online.
● Automatic battery temperature compensation function.
● Equipped with multiple expansion ports can access a variety of external equipment such as insulation monitoring devices, battery detection devices, etc.
● It has the function of "telemetry, remote control, remote signaling and remote adjustment", which can realize unattended operation.
● With battery automatic management and protection function.
● It is equipped with functions such as input voltage overvoltage alarm and protection, input voltage undervoltage alarm and protection, and output voltage overvoltage and undervoltage alarm and protection.
 
Normal use environmental conditions
● The ambient temperature is not higher than 45 ℃, not lower than 25 ℃, and the daily average temperature is not higher than 40 ℃.
● The altitude does not exceed 2000H.
● Daily average humidity is not more than 95%.
● When the equipment is installed, the inclination shall not exceed 5......
● No violent vibration around, no corrosive gas and conductive dust

The switch cabinet has the functions of overhead incoming and outgoing lines, cable incoming and outgoing lines, bus connection, etc. Mainly suitable for power plants, substations, petrochemical, metallurgical steel rolling, light industry and textile, factories and mining enterprises and residential areas, high-rise buildings and other different places. It mainly includes high-voltage isolating switch and grounding switch, high-voltage load switch, high-voltage automatic coincidence and segmenter, high-voltage operating mechanism, high-voltage explosion-proof distribution device and high-voltage switch cabinet.

Correct Selection of Breaker Breaking Capacity
On the primary system diagram, the selected circuit breaker, indicating the circuit breaker model, rated working voltage and rated working current, must also be selected for the breaking capacity of the circuit breaker. With user drawings, the breaking capacity of the circuit breaker is not selected, which makes it difficult for the manufacturer to carry out engineering design. The breaking capacity selection should be based on the system short-circuit parameters. If the manufacturer does not understand the system short-circuit parameters, it is difficult to make the correct choice. There are also some user drawings, regardless of the system short-circuit parameters, blindly select high-break parameters, resulting in unnecessary waste of funds. The correct choice of breaking capacity is very important, not only to ensure safe operation, but also to consider reducing product costs.
