保定零序电流互感器电气厂

电流互感器一次绕组的头、尾出线端分别用L1和L2标志(L2有时不标出);二次绕组的头尾出线端分别用K1和K2(或S1, S2)标志。L1和KI (S1)为同极性;L2和K2 (S2)为同极性。 The head and end of the current transformer are marked by L1 and L2 (L2 is sometimes not marked). The end of the second winding is marked by K1 and K2 (or S1, S2). L1 and KI (S1) are the same polarity; L2 and K2 are the same polarity. (1)电流互感器的一次应串联在被测电路中，其标有L1的端子应与电源相接，标有L2的端子应与负载(用电器)相接。 (1) the current transformer should be connected in a series in the measured circuit, and the terminals bearing L1 should be connected to the power supply, and the terminals of L2 should be connected to the load (using electrical appliances). 对穿芯式互感器，电源线应由标有L1的一端穿人，穿过后去接负载。电源线穿过互感器中心孔几次，即为几匝 For the core type transformer, the power line shall be worn by the end of the marked L1, and then carry the load through. The power line passes through the hole of the transformer center several times, which is a few turns (2)电流表或功率表的电流回路与电流互感器的二次K1(S1), K2 (S2)相接。与功率表的电流回路相接时，其K1 (S1)端应接功率表标有“*”的一端(该端被称为“发电机端”)。 (2) the current circuit of the ammeter or power meter is connected to the second K1 (S1) of the current transformer, and K2 (S2). When the current loop of the power table is connected, the K1 (S1) end of the power meter is marked with the "*" end of the power table (the end is called the "generator end"). (3)标有二次K2 (S2)端子和铁芯均应可靠接地。 (3) it is said that two K2 (S2) terminals and iron cores should be reliably grounded.
