Kontrola Dual Power Nintelejensia

Deskripsyon

Wíth the development of society, people have higher and higher requirements for power supply reliability. In many cases, two power supplies are used to ensure the reliability of power supply, which requires a product to switch reliably between two power supplies. The intelligent dual power automatic conversion device produced by our company is mainly composed of a high-voltage vacuum circuit breaker with electric dual isolation and a dual power intelligent backup self-input controller. Applied to AC 50HZ, rated voltage 12KV, rated current up to 1250A dual power supply system, when one power failure or undervoltage occurs, the isolation switch automatically switches to the other, the whole process automatically switches to the other normal power supply. Reliable guarantee of continuity of power supply

The controller has a variety of protection functions such as short circuit, three-stage overcurrent, single-phase ground, undervoltage, reclosing and prepaid, which effectively avoids unnecessary re-supply shock when the load fails. When the common power supply fails, the switching device can automatically switch with the standby power supply to ensure reliability and safety. It is especially suitable for important places where power is not allowed, as an important electrical control device to ensure continuous power supply, it is a self-throwing self-restoring dual power automatic switching device matching with high voltage vacuum circuit breaker. The products are widely used in 10kV distribution lines in oil fields and mines, and 10kV lines in industrial and mining enterprises to ensure real-time power supply of important loads. It has the characteristics of small footprint, small investment, convenient debugging and maintenance, and is an ideal switchgear for realizing power supply automation.

Support communication methods: wireless (GSM/GPRS/CDMA), Ethernet, WIFI, optical fiber, power carrier, RS232/485,RJ45, etc., and can access other station equipment (such as TTU, FTU, DTU, etc.).

Q: Ano nga high voltage dual power switch?

A: Ang high-voltage dual power switch ay isang aparato na ginagamit para sa automatic switching ngan dalawahan nga high-voltage power supplies. Kapag ang isa nga power supply ay nag-fail (tulad ng power failure, abnormal voltage, etc.), ito ay mabilis na mag-switch ngan load sa iba nga normal power supply para ma-ensure ang continuity ngan power supply.

Q: Saan nga lugar ito pangunahin ginagamit?

A: Sa ospital, data centers, malalaking factories, at iba pa nga lugar kung saan mataas ang requirement ngan continuity ngan power supply. Halimbawa, kapag may surgery sa ospital, ang biglaang pagkakawalan ngan power ay maaaring mapanganib sa buhay ng pasyente, at ang paggamit ng high-voltage dual power switch ay maaaring iwasan ito.

Q: Kailanig ito mag-switch?

A: Sa pangkalahatan, ang switching time ay maaaring maabot ang millisecond level, na maaaring minimize ang oras ngan load power failure at iwasan ang damage sa equipment.
