J series vacuum circuit breakers are produced and sold by ABB (China) Co., Ltd., which is invested and controlled by 70% of Shantou Yingzhao Switch Factory.The holder of the VEJ registered trademark is ABB (China) Co., Ltd., which is developed by ABB Group's Medium Voltage Product Technology Center and commissioned by ABB (China) Co., Ltd. for inspection.The product passed the complete type test in the Experimental Certification Center of Xi'an High Voltage Electric Apparatus Research Institute, and also in the power industry reactive power compensation complete set quality inspection test.
The center passed the open-close capacitor bank test and its performance reached C2-E2-M2. In addition, the circuit breaker passed the low temperature test verification at the 704th Research Institute of China Shipbuilding Industry Corporation.
VEJ adheres to ABB's product philosophy of reliability, ease of use and environmental protection:
-- Vacuum arc extinguishing: the original imported ABB vacuum foam, more than 30,000 times of service life, each vacuum bubble has a product number and customs declaration;
-- Operating mechanism: ABB's EL modular operating mechanism, low energy consumption, simple installation, easy to use, can be freely equipped with secondary accessories that can be installed quickly and easily, and maintenance-free operation within 10,000 times;
-- Solid-sealed pole: The casting material and VD4 are the same material provided by the same manufacturer, and the operation within 30,000 times is maintenance-free;
-- Split coil: use standardized products supplied by ABB;
-- Mechanical anti-jump: ABB's patented design does not require auxiliary contacts and does not conflict with the comprehensive protection anti-skip;
-- Pressure spring: The specially designed imported disc spring provides stable spring force to ensure reliable contact closing;
-- Plum contact: the thickness of the silver plated layer reaches 20Mm, ensuring good current carrying capacity and temperature rise margin;
-- Chassis: The chassis is designed in an integrated design for fast maintenance;
-- Panel: It adopts buckle design, which is quick to disassemble and easy to maintain.
