Abstract
The invention discloses a reactive power compensator which relates to the field of electrical devices. The reactive power compensator includes a casing, a contactor, busbars, busbar chambers and a switching switch. The busbars are connected with fuse protectors. The fuse protectors are connected with terminal strips. Electric reactors are arranged in the busbar chambers. The electric reactors are connected with capacitors. The number of the busbar chambers, the number of the busbars and the number of the terminal strips are all two. The electric reactors are only used under a condition that harmonic waves exist in a power supplying system. According to the harmonic-wave times and content, electric reactors of appropriate reactance rates are configured to form a detuning circuit. The electric reactors are connected with the capacitors. The number of the busbar chambers, the number of the busbars and the number of the terminal strips are all two so that the reactive power compensator is reasonable in structural arrangement and large in single-device capacity and has the advantages that the capacity can be flexibly and randomly increased or reduced so as to adapt to a phenomenon that devices are increased in an electrical unit for self development of the electrical unit so that the original compensation capacity is insufficient.
