RC-Absorber

Cut-off switch on the vacuum generated by the operation over-voltage protection device is a dedicated RC absorber (also known as RC protectors). In the United States and Japan and other developed countries, a vacuum switch with the RC matching absorber, it is more commonly used. As a result of China's medium-voltage (3 66KV) some of the special nature of the grid, in the past to absorb imports RC devices and the use of standard production of the domestic foreign RC absorbers are unable to adapt to China's actual conditions, often causes damage to do to help. This has LED to the product in China lags far behind the pace of development in a vacuum switch. However, after entering in 2002, with the RC-pressure system to improve the protection of theory and found a key factor in the problems. At present, grid absorber with RC, with the use of correct principles of production are broken free from the problems incidents, security is greatly improved, so that the products display a great vitality. This product is for high-frequency shock absorption devices, fast response, good response to small current, and vacuum discharge tube to achieve an ideal match. Not to provide additional grounding grid capacitance current, easy-to-use design. Combined use of a four-star three-phase grounding, to meet the actual situation of China's power grid, white and strong protection. Dry-type design, the whole closed structure, safe, durable, compact appearance. Model: ZR modular three-phase absorber RC: 1: A special type motor: 3.15 * KV, 6.3 * KV, 10.5 * KV; 2: B-type transformer GM: 3KV, 6KV, 10KV. 35KV. Note: 1: Capacitor DC voltage for the exchange of the pressure resistance of 1.8 to 2.0 times. And factory acceptance test pressure to obtain the maximum value of 50%; 2: The plateau-type products to be produced to strengthen, in the model after the "Q" or "GY" said; 3: The vast majority of products matching counter, monitor, etc. Accessories. With counters in the model after the "J", with additional monitor "IM"; 4: "System nominal voltage" column, with * the data protection products for the electric motor corresponding to rated voltage. RC composite Overvoltage Protection Series RC composite FGB overvoltage protection device 1: A special type motor (3.15 * KV, 6.3 * KV. 10.5 * KV); 2: B-type transformer common (3KV, 6KV. 10KV. 35 KV) Note: 1: The plateau-type products to be produced in the model after the "Q" or "GY" said; 2: The matching counter, monitor, the vast majority of products supporting counter, monitor and other accessories. With counters in the model after the "J", with additional monitor "IM"; 3: "System nominal voltage" column, with * the data protection products for the electric motor corresponding to rated voltage.
