Description
技术领域：Technical field:
本发明涉及电力设备加工改造技术领域，具体涉及待命零损耗电力箱自动散热装置。The invention relates to the technical field of power equipment processing and transformation, in particular to an automatic cooling device for a zero-loss power box on standby.
背景技术：Background technique:
在夏季随着用的客户用电量的增加表箱内的导线和器件都产生大量的热量。In summer, the wires and devices in the meter box all produce a large amount of heat along with the increase of the customer's electricity consumption.
而智能表部件中大量使用电子器件集成电路。众所周知，高温是电子器件集成电路的大敌。高温不但会导致智能表运行不稳，使用寿命缩短，甚至有可能使某些部件烧毁。导致高温的热量不是来自智能表外，而是智能表内部，或者说是集成电路内部。And smart watch components use a large number of electronic device integrated circuits. As we all know, high temperature is the enemy of electronic devices integrated circuits. High temperature will not only lead to unstable operation of the smart watch, shorten the service life, and may even burn some parts. The heat that causes high temperature does not come from outside the smart watch, but from inside the smart watch, or inside the integrated circuit.
这样就会在时间长久之后对于智能表造成损伤，可能会影响电力计量的稳定性和准确性，并且长时间容易损坏就需要更换，会带来极大的不方便和损失。This will cause damage to the smart meter after a long time, which may affect the stability and accuracy of power metering, and it will need to be replaced if it is easily damaged for a long time, which will bring great inconvenience and loss.

本发明的有益效果为：双金属片也称热双金属片，由于各组元层的热膨胀系数不同，当温度变化时，主动层的形变要大于被动层的形变，从而双金属片的整体就会向被动层一侧弯曲，则这种复合材料的曲率发生变化从而产生形变。其中，膨胀系数较高的称为主动层；膨胀系数较低的称为被动层。但是随着双金属应用领域的扩大和结合技术的进步，事实上，凡是依赖温度改变而发生形状变化的组合材料，现今在习惯上仍称为热双金属。The beneficial effects of the present invention are: the bimetal is also called thermal bimetal, because the thermal expansion coefficients of each component layer are different, when the temperature changes, the deformation of the active layer is greater than the deformation of the passive layer, so that the bimetal as a whole If it bends to the side of the passive layer, the curvature of the composite material will change to produce deformation. Among them, the higher expansion coefficient is called the active layer; the lower expansion coefficient is called the passive layer. However, with the expansion of bimetallic application fields and the advancement of bonding technology, in fact, all composite materials that change shape depending on temperature changes are still customarily called thermal bimetals.
本电路设计当箱内温度超过40°双金属片触点闭合导通、接通电源、风扇开始工作。This circuit is designed when the temperature in the box exceeds 40°, the bimetal contact is closed and conducts, the power is turned on, and the fan starts to work.
箱内温度低于40°时双金属片触点断开、切断电源、风扇停止工作。When the temperature in the box is lower than 40°, the bimetal contact is disconnected, the power supply is cut off, and the fan stops working.
