微型断路器由连接在输电线路上的固定式和活动式交流接触器组成。金属材料或通电部件采用电解铜或银铝合金，视隔离开关的额定电流而定。当接触点或负载在短路故障条件下分离时，就会产生电弧。所有现代的设计都是通过水冷金属板材料来解决电弧中断过程中获得的动能、电弧和电弧的分离装置。有一个绝缘层使金属板保持适当的位置。此外，通过流道的电弧呈现在主断路器的中间以强制电弧。

The miniature circuit breaker is composed of fixed and movable AC contactors connected to the transmission line. Electrolytic copper or silver aluminum alloy shall be used for metal materials or energized parts, depending on the rated current of the disconnector. When the contact point or load is separated under short-circuit fault conditions, an arc will be generated. All modern designs solve the kinetic energy obtained in the process of arc interruption, arc and arc separation device through water-cooled metal plate materials. There is an insulating layer to keep the metal plate in place. In addition, the arc passing through the flow channel appears in the middle of the main circuit breaker to force the arc.

大多数磁场跳闸装置由复合磁系统软件组成。系统软件在硅流体动力学中带有带磁性弹性塞的弹簧加载缓冲器，所有磁跳正常。跨接器中的载流线圈相对于弹簧向固定极移动。因此，当电磁线圈产生足够的电磁场时，抗拉肝上就会产生磁阻力。在短路故障或轻负载的情况下，由螺线管（螺线管）引起的强磁场，无论其在缓冲器中的位置如何，都会吸引跨接肝脏中的同步电机。

Most magnetic field trip devices consist of composite magnetic system software. The system software is equipped with spring-loaded buffer with magnetic elastic plug in silicon hydrodynamics, and all magnetic jumps are normal. The current carrying coil in the jumper moves towards the fixed pole relative to the spring. Therefore, when the electromagnetic coil generates enough electromagnetic field, magnetic resistance will be generated on the tensile liver. In the case of short-circuit fault or light load, the strong magnetic field caused by the solenoid (solenoid), regardless of its position in the buffer, will attract the synchronous motor in the jumper liver.

热脱扣器由一对紧紧围绕金属带状电热器的微型断路器组成，该金属带状电热器缠绕有电磁线圈，根据易流动电热器的电流量，使热量流动。立即能够设计出其中电流量的双金属片，从而危及电源电路部分，将电磁线圈或间接载流导体包裹在双金属片中。然后双金属条的刚性在某些负载条件下使肠组织绊倒。

The thermal release is composed of a pair of miniature circuit breakers closely surrounding the metal strip electric heater. The metal strip electric heater is wound with an electromagnetic coil to make the heat flow according to the current of the easy flowing electric heater. The bimetallic sheet in which the electric flow can be designed immediately, so as to endanger the part of the power circuit, and wrap the electromagnetic coil or indirect current carrying conductor in the bimetallic sheet. The rigidity of the bimetallic strip then trips the intestinal tissue under certain loading conditions.

双金属条由两种不同的金属材料制成，铜和钢。这种金属材料沿其长度进行铆接和焊接。金属的全部设计使它们不会轻易地将钢板加热到所有正常的电流跳闸点。但是，如果电流超过额定电流，钢带就会被加热、弯曲和跳闸。为特殊负载选择双金属条，显示特殊延迟时间。

Bimetallic strips are made of two different metal materials, copper and steel. This metal material is riveted and welded along its length. The overall design of the metal makes it difficult for them to easily heat the steel plate to all normal current trip points. However, if the current exceeds the rated current, the steel strip will be heated, bent and tripped. Select the bimetallic strip for the special load and display the special delay time.
