Vej Vacuum Circuit Breaker for Switchgear

Product : VEJ Vacuum circuit breakerIntroduction: more suitable for the requirements of cast pole, thus improving the reliability of the productModel : VEJInstallation: Switchgear / indoorType: Roll-out typeProduct DescriptionVEJ series vacuum circuit breakers are equipped with modular spring operating mechanism, integral cast pole, high-performance, long-life vacuum interrupter with small size, which is more suitable for the requirements of cast pole, thus improving the reliability of the product. The design concept of functional modularization can quickly diagnose faults, shorten maintenance time, and quickly restore power supply. It has excellent performance in occasions where frequent operation is required and/or where short-circuit current needs to be broken. It fully meets the requirements of automatic reclosing and has extremely high operational reliability and service life.VEJ vacuum circuit breaker complies with the relevant national and industry standards GB/T 1984-2014 ( IEC 62271-100-2008, MOD ) "High Voltage AC Circuit Breaker" and has passed the A full set of type tests have been passed, and the quality inspection and testing center of reactive power compensation complete sets of power industry has passed the split capacitor bank test, and the performance has reached C2-E2-M2 level. In addition, the circuit breaker has passed the low-temperature test verification in the No. 704 Research Institute of China Shipbuilding Industry Corporation.Feature:The VEJ series vacuum circuit breaker is equipped with a modular spring operating mechanism, and the integrally cast fully solid-sealed pole.VEJ vacuum circuit breakers comply with the corresponding national standard GB/T1984 and have passed a full set of type test verification (C2-E2-M2 level), and the product has also passed the -25C low temperature test.Professional vacuum extinguishing chamber fully solid-sealed poleReliable modular operating mechanism AC and DC universal line diagram moduleInnovative snap-on panel integrated chassisThe solid-sealed pole technology ensures that the vacuum interrupter is reliably protected from mechanical impact, dust and moistureInnovative functional modular design, compact size, spring energy storage operating mechanism, standard anti-jump function, stable performance and long service lifeFixed or withdrawable installation, complete secondary accessories and safety interlock solutions are availableStandard:GB/T 1984-2014 ( IEC 62271-100-2008, MOD )  modular operating mechanism VEJ vacuum circuit breaker adopts a modular mechanical operating mechanism with spring energy storage and free trip; opening and closing operation performance has nothing to do with the operator; energy storage and opening and closing can be operated manually , can also be operated by electric; this operating mechanism has low energy consumption, simple concept, easy to use, and can be freely selected with secondary accessories that can be installed easily and quickly; the circuit breaker has energy storage status, opening and closing status and operation times Instructions can be observed through the front panel; the simple design concept brings high reliability of components.2. The integrally cast fully solid-sealed pole vacuum interrupter is integrally cast in epoxy resin. The integrally cast pole structure is stronger, which can provide more sufficient protection for the vacuum interrupter and eliminate dust and The influence of moisture on the external insulation capacity of the arc extinguishing chamber, the inner and outer corrugated design of the pole, without additional creepage distance booster, the creepage distance can be greater than 240 mm, which fully meets the II pollution level specified in the DL standard Requirements for use under certain conditions; the arc extinguishing chamber permanently seals the main contacts of the switch in a vacuum environment to form an interrupting arc extinguishing unit; The optimal cooperation of the opening and closing performance of the chamber makes the overall performance of the circuit breaker safer and more reliable; at the same time, this compact structure also ensures the firmness and mechanical reliability of the circuit breaker.  Reliable safety interlock The circuit breaker is also equipped with a complete interlock function to prevent dangerous and erroneous operations: the front beam of the circuit breaker is equipped with a positioning interlock, which is matched with the switch cabinet, and only the handcart is completely The handle on the beam can only be moved when it is shaken to the test position (the chassis of the handcart and the beam are completely close together). The operating handle of the handcart must be in place when inserted, so that the circuit breaker can be operated in and out. When the grounding switch is closed, there is a locking device that prohibits the circuit breaker from swinging into the working position. The locking device locks the circuit breaker i
