型号及含义/Type and meaning 结构特征/Structure features

X L - 21 □ XL-21低压控制柜(动力柜)系封闭式，外壳用钢板压制而成，刀开关操作手柄装于前右柱上部，可以作
为切换电源之用。配电箱前面装有一只电压表，指示母线的电压。配电箱前面有门，门打开后配电箱
内全部设备敞露、便于检修维护。本配电箱用用国内自行设计的型组件，具有结构紧凑，检修方便，
线路方案可以灵活组合等特点。配电箱除装有空气断路器和熔断器作为短路保护外，还装有接触器和
方案号/Scheme No. 热继电器，箱前门可装操作按钮和指示灯。
设计序号/Design No. The XL-21 low-voltage control cabinet (power cabinet) is enclosed, the outer casing is made of steel
动力控/Power control plate, and the knife switch operating handle is mounted on the upper part of the front right column,
控制柜/control cabinet which can be used as a switching power source. A voltmeter is placed in front of the distribution box
to indicate the voltage of the bus. There is a door in front of the distribution box. After the door is
opened, all the equipment in the distribution box is exposed, which is convenient for maintenance and
repair. The distribution box uses domestically designed components, which has the characteristics of
compact structure, convenient maintenance and flexible combination of line schemes. In addition to
the air circuit breaker and fuses, the distribution box is equipped with a contactor and a thermal relay.
The front door of the box can be equipped with operation buttons and indicator lights.
