J1206型感应圈是供中等学校物理、化学教学及实验室中作小功率高压电源用,小学自然也可作雷电现象的演示。但感应圈中的断续器由于其结构原因,白金触点往往接触不良,易脱落,操作使用不便。为此江西省吉安市科教仪器厂,对断续器装置进行了改进,几年来获得广大用户的好评。现介绍如下,供参考。 The J1206 induction coil is used for the low-power and high-voltage power supply in the physics and chemistry teaching in the middle school and in the laboratory. The demonstration of the lightning phenomenon in the primary school is also natural. However, due to the structural reasons, the interrupter in the induction coil is often in poor contact with platinum contacts and is inconvenient for operation and use. To this end, Ji’an Science and Education Instrument Factory in Jiangxi Province, the interrupter device has been improved over the past few years to obtain the majority of users. The introduction is as follows, for reference.
