LE109A-1高压断路器是一种用于断开或接通高压电路的电气设备。其主要原理是利用电磁力作用，将断路器的触头打开或关闭，从而断开或接通高压电路。当主触点闭合后，自由脱扣机构将主触点锁在合闸位置上。过电流脱扣器的线圈和热脱扣器的热元件与主电路串联，欠电压脱扣器的线圈和电源并联。当电路发生短路或严重过载时，过电流脱扣器的衔铁吸合，使自由脱扣机构动作，主触点断开主电路。当电路过载时，热脱扣器的热元件发热使双金属片上弯曲，推动自由脱扣机构动作。当电路欠电压时，欠电压脱扣器的衔铁释放。也使自由脱扣机构动作。分励脱扣器则作为远距离控制用，在正常工作时，其线圈是断电的，在需要距离控制时，按下起动按钮，使线圈通电。

LE109A-1 AC circuit breaker is the main power control equipment of the substation. When the system is running normally, it can cut off and connect the no-load and load current of the line and various electrical equipment. When the system fails, it and relay protection cooperate to quickly cut off the fault current to prevent expanding the scope of the accident. Therefore, the working quality of the high-voltage circuit breaker directly affects the safe operation of the power system.

The characteristics of the LE109A-1 AC circuit breaker include the form of the circuit breaker (number of poles, current type), the rating and limit value of the main circuit (including short circuit characteristics), the control circuit, the auxiliary circuit, the release form (shunt release, overcurrent release, undervoltage release, etc.), and the operating overvoltage.

The working principle of the high-voltage circuit breaker is to use the electromagnetic force to open or close the contact of the circuit breaker, so as to disconnect or connect the high-voltage circuit.

The LE109A-1 high-voltage circuit breaker is an electrical device used to disconnect or connect high-voltage circuits. The main principle is to use the electromagnetic force to open or close the contact of the circuit breaker, so as to disconnect or connect the high-voltage circuit. When the main contact is closed, the free trip mechanism locks the main contact in the closing position. The coil of the overcurrent release and the thermal element of the thermal release are connected to the main circuit in series, and the coil of the undervoltage release is connected to the power supply in parallel. When the circuit occurs short circuit or serious overload, the armature of the overcurrent trip device draws, making the free trip mechanism operate, and the main contact disconnects the main circuit. When the circuit is overloaded, the heat element of the thermal trip device heats up to bend the bimetal sheet and push the free trip mechanism to act. When the circuit is under voltage, the armature of the undervoltage releaser is released. Also allows the free trip mechanism to operate. Shunt release is used as a remote control, in normal operation, the coil is powered off, in the need of distance control, press the start button to make the coil powered.
