Description

變頻機櫃Frequency conversion cabinet

本新型係有關於一種變頻機櫃，特別是有關於一種可活動更換變頻模組之變頻機櫃。The present invention relates to a frequency conversion cabinet, and more particularly to a frequency conversion cabinet for a movable replacement frequency conversion module.

電源設備需要變頻模組進行電壓之升降，以符合特定電氣裝置（如馬達裝置）之電源需求。變頻模組可整合至一機櫃體內，以藉此經由機櫃體與所述之電氣裝置進行電氣導接。傳統方式中，變頻模組之輸入端與輸出端都是透過螺絲而鎖固至機櫃體之電氣端子上，以便藉此達成變頻模組與機櫃體的電氣導接。The power supply device requires a frequency conversion module to perform voltage rise and fall to meet the power requirements of a specific electrical device such as a motor device. The frequency conversion module can be integrated into a cabinet body to thereby electrically conduct electrical connection with the electrical device via the cabinet body. In the conventional method, the input end and the output end of the frequency conversion module are locked to the electrical terminals of the cabinet body through screws, so as to achieve electrical connection between the frequency conversion module and the cabinet body.

然而，由於變頻模組是透過螺絲鎖固於機櫃體上，故，每當組裝或拆卸變頻模組時，往往需要將螺絲一一地鎖上或卸下，相當耗費組裝時間與成本，也不利組裝便利性的提昇。此外，上述之鎖固過程中，組裝者有時不慎將螺絲落入變頻模組內部時，便需要耗費時間取出螺絲，不僅增加時間與成本，也提高變頻模組產生故障之風險。However, since the frequency conversion module is fixed to the cabinet body by screws, when the frequency conversion module is assembled or disassembled, it is often necessary to lock or remove the screws one by one, which is quite expensive to assemble and cost, and is disadvantageous. Increased assembly convenience. In addition, in the above-mentioned locking process, when the assembler accidentally drops the screw into the interior of the frequency conversion module, it takes time to remove the screw, which not only increases the time and cost, but also increases the risk of failure of the inverter module.

為此，若能提供一種解決方案的設計，可解決上述需求，讓業者於競爭中脫穎而出，即成為亟待解決之一重要課題。To this end, if we can provide a solution design that can solve the above requirements and let the industry stand out from the competition, it becomes an important issue to be solved urgently.

須瞭解的是，本新型所述之變頻模組的第二免工具輸入接頭與第二免工具輸出接頭在分別插接機櫃體之第一免工具輸入接頭與第一免工具輸出接頭時，不需藉由任何工具（如螺絲起子等）或接合件（如螺絲、卡榫）以達成變頻模組與機櫃體之結合，只要變頻模組被推入接機櫃體內時，順勢讓第二免工具輸入接頭插接第一免工具輸入接頭，第二免工具輸出接頭插接第一免工具輸出接頭，即可達成變頻模組與機櫃體之結合。It should be understood that the second toolless input connector and the second toolless output connector of the frequency conversion module of the present invention are not respectively inserted into the first toolless input connector and the first toolless output connector of the cabinet body. It is necessary to use any tool (such as a screwdriver) or a joint (such as a screw or a cassette) to achieve the combination of the inverter module and the cabinet body. As long as the inverter module is pushed into the cabinet body, the second tool is allowed. The input connector is plugged into the first tool-free input connector, and the second tool-free output connector is plugged into the first tool-free output connector to achieve the combination of the frequency conversion module and the cabinet body.

以下免工具輸入接頭與免工具輸出接頭之變化僅為其中一種實施方式，並作為本新型之限制種類。The following changes to the tool-free input and tool-free output connectors are only one of the implementations and are a limiting type of the present invention.

請參閱第2圖、第3圖所示。第3圖繪示本新型變頻機櫃100朝正面方向觀察第二免工具輸入接頭600P、600N與第一免工具輸入接頭300P、300N相耦合之操作示意圖。Please refer to Figure 2 and Figure 3. FIG. 3 is a schematic diagram showing the operation of the second toolless input connectors 600P, 600N coupled to the first toolless input connectors 300P, 300N in the front direction of the novel inverter cabinet 100.

本新型之一實施例中，每一第一免工具輸入接頭300P或300N包含多個第一彎折彈片310與多個第二彎折彈片320。此些第一彎折彈片310朝一第一方向D1並排。第一方向D1為機櫃體200的頂部201至底部202的延伸方向（第2圖）。此些第二彎折彈片320亦朝此第一方向D1並排，此時，此些第一彎折彈片310與此些第二彎折彈片320可部份接觸，或至少其一部分彼此接近，以致此些第二彎折彈片320與此些第一彎折彈片310共同形成一第一夾合結構330。In one embodiment of the present invention, each of the first toolless input connectors 300P or 300N includes a plurality of first bending elastic pieces 310 and a plurality of second bending elastic pieces 320. The first bending elastic pieces 310 are arranged side by side in a first direction D1. The first direction D1 is an extending direction of the top 201 to the bottom 202 of the cabinet body 200 (Fig. 2). The second bending elastic pieces 320 are also arranged side by side in the first direction D1.

The second direction D2 is the traveling direction of the inverter module 500 into the accommodating space 220 (Fig. 2).

如第3圖所示，如此，當變頻模組500進入容置空間220時，第一金屬片體610之另端直接***第一夾合結構330內，被第一夾合結構330所挾持，此時第一彎折彈片310與第二彎折彈片320彼此被撐離，以便第一彎折彈片310與第二彎折彈片320可緊密地接觸第一金屬片體610，並與第一金屬片體610電性連接。As shown in FIG. 3 , when the inverter module 500 enters the accommodating space 220 , the other end of the first metal piece 610 is directly inserted into the first clamping structure 330 and is held by the first clamping structure 330 . At this time, the first bending elastic piece 310 and the second bending elastic piece 320 are separated from each other, so that the first bending elastic piece 310 and the second bending elastic piece 320 can closely contact the first metal piece body 610 and the first metal The body 610 is electrically connected.

It is an alternating current that conforms to the specifications of the motor unit 830.

如此，當供應電源810提供交流電至整流模組820時，整流模組820將供應電源810之交流電轉換為直流電，直流電再被送至變頻模組500。當直流電被電容單元520進行濾波後，藉由微處理器單元550之控制，前述供應電源810之直流電被調變其頻率以轉換為符合馬達裝置830規格之交流電。As such, when the power supply 810 supplies AC power to the rectifier module 820, the rectifier module 820 converts the AC power supplied to the power source 810 into DC power, and the DC power is sent to the inverter module 500. After the DC power is filtered by the capacitor unit 520, the DC power of the supply power source 810 is modulated by the frequency of the microprocessor unit 550 to be converted into an AC power that conforms to the specifications of the motor device 830.
