SWX-13-10/60-120无载分接开关供三相中性点调压使用，电压等级为10千伏，负载电流限值60A和120ASWX-13-10/60-120 no-load tap changer is used for three-phase voltage regulation, with the voltage being 10 kilovoltage and the limited value of load current being 60A and 120A.2. 在操作分接开关时，必须严格禁止带电操作。Hot-line work is strictly forbidden in operating the tap changer.7.2无载分接开关的结构Structure of no-load tap changer1. 此种分接开关，采用一个M422的圆螺母，将开关吊装于变压器油箱盖下，为使分接开关暴露于空气中之部分全部密封，采用一个手柄罩，操作分接开关时，必须旋下该手柄罩。This kind of tap changer adopts a M422 round nut, which hangs the tap changer under the oil tank cover of the transformer. In order to seal all the parts of the tap changer exposed in the air, a handle cover is used; screw off the handle cover when operating the tap changer.2. SWX-13-10/60-120无载分接开关（如图2所示），9个定触头按40间隔固定于绝缘座盘上，绝缘座盘上端固定在法兰盘上，法兰盘又被一个M422圆螺母固定在变压器的箱盖下，动触头套在中心的绝缘柱下端，上半轴与法兰盘间有密封装置，上部装有手柄和定位件，可以指示出开关所处之位置，当旋转手柄时，动触头随上半轴绝缘柱转动到相应的定触头上，为防止整个分接开关转动，在箱盖下焊装一个卡板。Nine fixed contactors of SWX-13-10/60-120 no-load tap changer(as shown in Diagram 2)are fiexed on the insulation base with 40 space. The top end of the insulation base is fixed on the ring flange while the ring flange is fixed under the tank cover by a M422 round nut. Moving contactor is positioned at the lower end of the central insulation post. There is sealing device between the upper axle and the ring flange. The handle and the locating piece are set on the top, showing the position the switch points. When rotating the handle, moving contactor moves to the corresponding position of the fixed contactor following the movement of the upper axle of the insulation post. A snap-gauge is welded under the tank cover in order to prevent the turning of the whole tap changer.7.3无载分解开关的工作原理和手动操作Working principle and manual operation of no-load tap changer1SWX-13-10/60-120无载分接开关与变压器线圈联接图。 （图1）Linkage diagram of SWX-13-10/60-120 no-load tap changer and the transformer coil (Diagram. 1)Carrete del transformadorContactor movibleDiagrama 12.由第1条所示三相线圈图中可以看出，当分接开关改变位置时，相应地改变了变压器线圈的匝数，即改变了变压器的电压。 From the three-phase coil as shown in the above item 1, it can be seen that the position change of tap changer will correspondingly change the number of windings of transformer coil, that is to say, it changes the voltage of the transformer.3无载分接开关的操作方法，首先应切断电源，旋下手柄罩，将定位件向上拔平，用手旋转手柄，使其箭头对准数字牌上所需档位，再把定位件按进相对应的槽口，最后旋紧手柄罩。 No-load tap changer operates in the following way: first cut off the power supply, screw off the handle cover, pull out the locating piece upward, screw the handle with the hand to make the arrow point at the desired gear on the numerical plate, press the locating piece into the corresponding groove, and finally screw the hanle cover tightly.7.4分接开关的维护和检修Maintenance and Overhauling of the tap changer1. 无载分接开关经常在一个位置上工作时，为消除触头部分氧化膜及油污等物，保证接触良好，不论变压器是否需要改变电压，每年至少要转动分接开关10周以上。如果不需更改变电压时，在转动后仍旧固定在原来的位置上，转动方法按本使用说明书第7条进行。If the no-load tap changer often works in the same position, in order to remove the oxide coating and grease and ensure better contact, it is necessary to turn the tap changer at least 10 rounds every year, no matter whether the transformer needs to change the voltage or not. If the voltage is unnecessary to change, fix to the original position after turning. The turning
