摘要： A heat-dissipating structure for a variable speed drive (VSD), a VSD device having the heat-dissipating structure, and a method for controlling the heat-dissipating structure. The heat-dissipating structure comprises: an electronic element array, having a first end and an opposite second end, electronic elements in the array producing heat during operation; a heat-dissipating fan, disposed at the first end of the array and used to conduct cooling air to flow between the first end and the second end to cool the electronic elements in the array; and a control apparatus, for controlling operation of the fan, the control apparatus controlling the fan so that the fan rotates at a first rotation direction within a first time period to conduct the cooling air to flow from the second end to the first end, and rotates at a second rotation direction contrary to the first rotation direction within a second time period to conduct the cooling air to flow from the first end to the second end.
摘要翻译：用于变速驱动器（VSD）的散热结构，具有散热结构的VSD装置和用于控制散热结构的方法。散热结构包括：电子元件阵列，其具有第一端和相对的第二端，所述阵列中的电子元件在操作期间产生热量; 散热风扇，设置在阵列的第一端，用于使冷却空气在第一端和第二端之间流动，以冷却阵列中的电子元件; 以及用于控制风扇的操作的控制装置，控制风扇的控制装置使得风扇在第一时间段内以第一旋转方向旋转，以使冷却空气从第二端流向第一端，并且在第二时间段内与第一旋转方向相反地在第二旋转方向旋转，以使冷却空气从第一端流到第二端。

摘要： The object of the present application is to ensure the security of a device when a precharging relay is not closed and a load current passes through a precharging resistor, so as to ensure the customer's security. Provided is a security control method for a system with a precharging circuit, comprising: giving out an error alarm and stopping operating the system when the number of times of undervoltage of a precharging circuit achieves m times and the duration between the first undervoltage and the mth undervoltage is less than or equal to τ seconds, where m and τ are positive integers. Compared with the previous method, the present invention has the following advantages of no danger of combustion and high reliability; and cost saving and no need of adding additional hardware.
摘要翻译：本申请的目的是确保在预充电继电器未闭合并且负载电流通过预充电电阻器时设备的安全性，以确保客户的安全性。提供一种用于具有预充电电路的系统的安全控制方法，包括：当预充电电路的欠压次数达到m次时，发出错误报警和停止操作系统，以及第一次欠压与第m次之间的持续时间欠压小于或等于τ秒，其中m和τ是正整数。与上述方法相比，本发明具有燃烧危险性高，可靠性高的优点，并节省成本，无需添加额外的硬件。
