电流开关装置

This paper gives out the principles and improving schemes of transformer discharge equipment and resonance booster discharge equipment. By detecting the current in the main circuit, the gap's breaking-down can be identified, and the single chip micro-computer will send out corresponding control signal to make the IGBTs to switch off or cut off the input voltage, by this mean, we can make sure that every time of the experiment, the sample will discharge only once. The paper also introduces the principle of the protection circuit. At last, the experimental waveforms were listed, which prove the feasibility of the high voltage discharge fast switch-off device.

该文给出了变压器和谐振升压器2种高压放电试验装置的原理以及改进方案，通过检测主回路电流大小判断间隙是否被击穿，由单片机发出相应控制信号，采用IGBT等开关器件控制试验电压的通断，保证了试品每次试验只进行一次放电，介绍了保护电路的原理，给出了试验波形，证明了此高压放电速断装置的可行性。

From the burden increased aspect clarify set up the necessity of station, then pass to drew up to set up generalize of transformer substation and line direction to consider, and pass to analysis of carry the data, safety, economic and dependable consider and made sure the 110 kV, 35 kV, 10 kV and station use electricity of lord connect line, then again through burden calculation and power supply scope made sure main number, capacity and model number of the transformer set, also in the meantime make sure the station uses capacity and model number of transformer, end, according to biggest keep on work electric current and short circuit calculating of calculation result, to the high pressure Rong break a machine, insulate a switch, female line, insulate son and wear a wall set tube, electric voltage with each other feeling machine, electric current with each other the feeling machine carried on choose a type, thus completed a 110 kV electricity a part of design.

本文首先根据任务书上所给系统与线路及所有负荷的参数，分析负荷发展趋势。从负荷增长方面阐明了建站的必要性，然后通过对拟建变电站的概括以及出线方向来考虑，并通过对负荷资料的分析，安全，经济及可靠性方面考虑，确定了110kV ，35kV ，10kV 以及站用电的主接线，然后又通过负荷计算及供电范围确定了主变压器台数，容量及型号，同时也确定了站用变压器的容量及型号，最后，根据最大持续工作电流及短路计算的计算结果，对高压熔断器，隔离开关，母线，绝缘子和穿墙套管，电压互感器，电流互感器进行了选型，然后进行配电装置和平面布置的设计以及防雷的设计，从而完成了110kV 电气一次部分的设计。

The improvement of the main switch and the discharge chamber was also conducted, that leads to increasing the discharge current amplitude and restraining the unwished discharge paths.

最后对主开关和放电室进行了改进，提高了放电电流的幅值，抑制了放电室中的旁路放电，提高了装置的性能。
