| 一次消谐是安装在6-35KV电压互感器一次绕组中性点与地之间的一种非线性电阻消谐阻尼器件，可起到限制电压互感器铁磁谐振的效果。 Primary harmonic elimination is a kind of non-linear resistance harmonic elimination damper installed between the neutral point of primary winding and ground of 6-35KV voltage transformer, which can limit ferroresonance of voltage transformer. 二次消谐也叫微机消谐，该装置是监测并显示PT开口三角电压17HZ、25HZ、50HZ、150HZ四种频率，当发生铁磁谐振时，装置瞬时启动无触点消谐元件，产生强大阻尼，从而消除铁磁谐振。 Secondary harmonic elimination is also called micro-computer harmonic elimination. The device monitors and displays four frequencies of PT open triangular voltage 17HZ, 25HZ, 50HZ and 150HZ. When ferroresonance occurs, the device instantaneously starts the non-contact harmonic elimination element to produce strong damping, thereby eliminating ferroresonance. 一次消谐与微机消谐是可以同时装的，一次消谐串接在电压互感器高压中性点与大地之间，二次消谐装置并接在电压互感器二次开口三角端。两者优势互补，能更好的治理电网系统中的谐振。 The primary harmonic elimination and the computer harmonic elimination can be installed simultaneously. The primary harmonic elimination is connected in series between the high voltage neutral point of the voltage transformer and the earth, and the secondary harmonic elimination device is connected in parallel with the secondary open triangle end of the voltage transformer. The two complementary advantages can better control the resonance in the power grid system. |
