Compensation device non-contact switch

本实用新型涉及一种补偿装置无触点开关。The utility model relates to a non-contact switch of a compensation device.

众所周知，无功补偿装置对电力系统非常重要，应用范围非常广泛，但是，由于老式静态补偿装置以交流接触器作开关器件，不能快速跟踪负载变化，投切时间长，导致不能频繁投切，另外由于电容器投入时的涌流和切除时的过电压，更加速了老式设备的损坏速度，致使对电力系统很重要的补偿装置不能起到应有的作用。As we all know, reactive power compensation devices are very important to power systems and have a wide range of applications. However, because the old-fashioned static compensation devices use AC contactors as switching devices, they cannot quickly track load changes, and the switching time is long, resulting in frequent switching. In addition Due to the inrush current when the capacitor is put in and the overvoltage when it is cut off, the damage speed of the old-fashioned equipment is accelerated, so that the compensation device that is very important to the power system cannot play its due role.

针对现有技术存在的缺点，本实用新型的目的在于提供一种补偿装置无触点开关，有效提供电力系统的补偿作用，以实现快速投切、动态补偿，解决设备易损的问题。Aiming at the shortcomings of the existing technology, the purpose of this utility model is to provide a non-contact switch of the compensation device, which can effectively provide the compensation function of the power system, so as to realize fast switching and dynamic compensation, and solve the problem of vulnerable equipment.

熔断器排列于两个可控硅模块之间，可控硅模块、熔断器两端为接线端子。The fuse is arranged between the two thyristor modules, and the two ends of the thyristor module and the fuse are terminals.

设有金属罩壳和上述散热片连接，可控硅模块、熔断器设于金属罩壳内。A metal casing is provided to connect with the above-mentioned heat sink, and the thyristor module and the fuse are arranged in the metal casing.
