Introduction

Weishun Electric is devoted to bringing our customers the products with best balanceof price and performance. The HYVZ Series solid dielectric Automatic Circuit Recloser (ACR) represents Houyuan Electric'S promise to endless improving and ongoing developments.

The automatic circuit reclosers are designed for use on overhead distribution lines as well as distribution substation of voltage class up to 38kV.

The tanks are manufactured from stainless steel and powder coated in light grey colour. The product is equipped with a BC300 or BC500 controller. The microprocessor based controller, BC300 or BC500, combines all functions in a single cubicle, including protection, data logging, communication and so on. With built-in communication methods, it is designed as a stand-alone device that can be easily integrated into distribution automation and remote control system.

The product is thoroughly type tested in Houyuan independent laboratory to ensure long life and excellent performance under various environmental conditions.

Overview of Switchgear

● Ganged Operation of Magnetic Actuator The switchgear is operated by a single magnetic actuator ganged with the three vacuum interrupters for both tripping and closing.

● Robust Epoxy Resin Housing The vacuum interrupters are enca psulated with robust hydrophobic epoxy resin housing of unibody casting, featuring thorough insulation to ensure paramount dielectric characteristic.

● Rugged Powder Coated Tank The magnetic actuator and associated mechanism is enclosed in the rugged powder coated tank. The strong base with special surface finishing ensures the capability of working under various environmental conditions.

● The hydrophobic epoxy resin housings are firmly bolted to the lid.

● An external pointer, clearly visible on the base of tank, indicates the“open”or“closed" state of the switchgear. Red for“closed” and Green for“open” ，pulling the yellow ring with hot stick to manually latch the switchgear to “open”

Description of Controller

Controller

The Microprocessor based controller provides protection, control, monitoring, instrumentation and metering with integrated input and output logic, data logging & fault report.

Communication functionality of the controller is achieved via electrical RS485 port for remote connection. Additional rear ports including RS232 are available for selection.

The Feeder Terminal Unit(FTU) is the core of controller. To prevent any damage to FTU from emergency, the control cubicle contains auxiliary power supply of batteries for uninterruptible power supply, electronic boards and circuit breakers.

A series of protection functions can be set via screen display.
