1200870502 is a multifunctional integrated electrical switchgear module designed for high-voltage substation switchgear, which is widely used in urban electrical networks with various harsh working conditions, such as high altitude and cold climates. In addition to providing range of functions, 1200870502 model also has a compact size and easy installation and maintenance, which makes it suitable for urban substations. In this article, we will discuss the application field and working principle of 1200870502 switchgear.

1200870502 switchgear is mainly applied in substations of 35KV, 6.3KV, 10/0.4KV and 24.5KV. The switchgear is running in all kinds of fields, such as urban and industrial production. It realized the purpose of system and power dispatch, protection and control. 1200870502 switchgear provides a reliable electric power supply, hence it can help to ensure urban production security in many aspects.

The working principle of 1200870502 switchgear is very simple. When the voltage applied to the switchgear is in the range of 6.3-6.4kV, the closing of the switchgear will be postponed, thus ensuring the stable application of the equipment. When the voltage is out of range, the switchgear will close automatically in a few milliseconds, which will effectively protect the power equipment from damage. Additionally, the switchgear also has an advanced control system, as it can identify the type of fault (short circuit, overload, etc.), and take the appropriate measures according to the type of fault.

The working principle of 1200870502 switchgear can be divided into the following steps: first, when the voltage is within the acceptable range, the signal of the synchronization will be transferred to the other end of the switch, and the relay will be energized. When the voltage reaches the closing voltage, the signal of the synchronization will be blocked, and the relay will be off. Then, the contactor will open the circuit, thus preventing the transfer of the excessive current. When the voltage is out of range, the relay will close the contactor, and then the switch will close.

The 1200870502 switchgear is designed to facilitate power supply system, which helps to ensure the security and stability of the power system. To ensure the reliable operation of the switchgear, the manufacturer will deliver a full set of complete spare parts and detailed operating instructions. The simple installation process and reliable performance of the 1200870502 switchgear makes it the ideal choice for electricians.
