Introducing the revolutionary YZD-12 type outdoor H.V. pre-paid control device - the ultimate solution for managing power usage and tackling the challenges of power cost recycling! We understand the difficulties faced in controlling big power users, which is why we have developed this cutting-edge product.
Designed for use in electric systems operating at AC 50 Hz and voltage 7.2~12kV, our YZD-12 control device serves as an automatic recloser under pre-paid H.V. measurement or distribution network automation projects. The host machine boasts a range of impressive features, including the ZW8-12 vacuum circuit breaker, dry type voltage transformer, and current transformer - all integrated into a single installation.
The top of the case houses the vacuum circuit breaker, while the bottom accommodates the transformer apartment. With its handle opening and closing spring mechanism, the YZD-12 control device offers unmatched convenience and ease of use. Additionally, the control case can be installed separately, allowing for the optional installation of a pre-paid ammeter as per the user's requirements.
Our H.V. vacuum circuit breaker is equipped with a spring mechanism and mechanical locking, ensuring optimal performance and safety. The switching apartment and transformer apartment are housed within the sturdy case, providing a reliable and efficient solution for power management.
Say goodbye to power usage woes and skyrocketing costs with our 12kv High Voltage Pre-Paid Control Circuit Breaker on Pole. This game-changing product is a must-have for anyone seeking to take control of their power consumption. Don't miss out on this incredible opportunity to revolutionize your power management system!
a. This system is composed of H.V. measurement control device and vacuum circuit breaker, as a set with disconnecting switch and arrester to fulfill the electric measurement and power pre-purchasing for users.
b. Adopt an electricity meter for measurement and clearing.
c. Through buying an electricity power card for using the electricity, each measurement case matches with one dedicated electricity power card and non-exchange.
d. Data valid for purchasing once, data out automatically after insert card, function with anti-magnetic, anti-static, and encryption indecipherability.
e. Pulling out the card and preservation, reserving it for next time use. If damage or loss, compensation could be available at the sale power department according to the user's record.
f. Balanced electricity, used electricity or other power using parameters could be checked from the display screen of the device.
g. Sound and light alarms when balanced electricity reaches the alarming threshold, reminding users to buy electricity in time.
h. It is reliable to break the load current when the purchasing electricity goes to zero, so that get the solution for the worrying about defaulting electricity charge.
i. Function with anti-stealing electricity. This device adopts an outdoor transformer for the measurement, the meter is installed inside the measurement case, so it solves the electricity stealing problem radically.
