防水按钮开关的作用：

　　Functions of waterproof button switch:

　　1、用于隔离电源，将高压检修设备与带电设备断开，使其间有一明显可看见的断开点。

　　1. It is used to isolate the power supply and disconnect the high-voltage maintenance equipment from the live equipment, so that there is an obvious disconnection point between them.

　　2、防水按钮开关与断路器配合，按系统运行方式的需要进行倒闸操作，以改变系统运行接线方式。

　　2. The waterproof button switch and the circuit breaker cooperate to change the operation mode of the system according to the needs of the system operation mode.

　　3、在操作防水按钮开关时应注意，线路送电时先合母线侧的防水按钮开关，后合线路侧防水金属开关，再合断路器。线路停电时应先断开断路器，后拉开防水按钮开关。不能带负荷拉、合高压防水按钮开关。

　　3. When operating the waterproof button switch, it should be noted that the waterproof button switch on the bus side should be closed first, then the waterproof metal switch at the line side, and then the circuit breaker. In case of power failure, the circuit breaker shall be disconnected first, and then the waterproof button switch shall be opened. Do not pull or close the high-pressure waterproof button switch with load.

　　4、用以接通或断开小电流电路。

　　4. It is used to connect or disconnect small current circuit.

　　防水按钮开关可以进行以下操作：

　　The waterproof button switch can perform the following operations:

　　可以拉、合闭路开关的旁路电流；

　　It can pull and close the bypass current of the closed circuit switch;

　　拉、合变压器中性点的接地线，但当中性点上接有消弧线圈时，只有在系统无故障时，方可操作；

　　Pull and close the grounding wire of transformer neutral point, but when arc suppression coil is connected to the neutral point, it can be operated only when there is no fault in the system;

　　拉、合电压互感器和避雷器；

　　Pull and close voltage transformer and lightning arrester;

　　拉、合母线及直接连接在母线上设备的电容电流；

　　The current and capacitor connected to the bus bar directly;

　　拉、合电容电流不超过5安的空载线路。

　　No load line with capacity current less than 5 a.

　　防水按钮开关的选择标准:

　　Selection standard of waterproof button switch:

　　1、防水开关设计合理，使用寿命长，耐高温，耐高电流冲击，能够您的产品的具体需求，这是应该考虑的。

　　1. The waterproof switch has reasonable design, long service life, high temperature resistance and high current impact resistance. It can meet the specific requirements of your products, which should be considered.

　　2、应用注意事项：对于这些防水按钮开关的具体应用，受到诸多因素的制约，如：安装方法以及产品的安装方向、气流、作用在产品上的压差、流体反弹的强度以及工作电压等等。

　　2. Application notes: the specific application of these waterproof button switches is restricted by many factors, such as: installation method and product installation direction, air flow, pressure difference acting on the product, fluid rebound strength and working voltage, etc.
