活接在門(mén)板上的手柄連接連桿，連桿安裝在斷路器上，連桿中部咬合擺板，擺板下面對(duì)應(yīng)銷(xiāo)軸，銷(xiāo)軸套上彈簧插入軸套內(nèi)，用螺栓將軸套固定在彎板上，彎板固定在左側(cè)板和右側(cè)板上，銷(xiāo)軸上有一凸臺(tái)壓在彈簧上，銷(xiāo)軸下端對(duì)準(zhǔn)開(kāi)關(guān)柜體上的托板的小孔。具有聯(lián)鎖機(jī)構(gòu)簡(jiǎn)單、可靠并且抽屜互換靈活等優(yōu)點(diǎn)。

The handle flexibly connected to the door plate is connected with the connecting rod, which is installed on the circuit breaker, the middle of the connecting rod engages the swing plate, the lower part of the swing plate corresponds to the pin shaft, the spring on the pin shaft sleeve is inserted into the shaft sleeve, the shaft sleeve is fixed on the bending plate with bolts, the bending plate is fixed on the left and right plates, a boss on the pin shaft is pressed on the spring, and the lower end of the pin shaft is aligned with the small hole of the support plate on the switch cabinet body. The utility model has the advantages of simple interlocking mechanism, safety and reliability, and flexible drawer exchange.

MNS型低壓開(kāi)關(guān)柜框架為組合式結(jié)構(gòu)，基本骨架由C型鋼材組裝而成;MNS型組合式低壓開(kāi)關(guān)柜的每一個(gè)柜體分隔為三個(gè)室，即水平母線(xiàn)室(在柜后部)，抽屜小室(在柜前部)，電纜室(在柜下部或柜前右邊)。

The frame of MNS low-voltage switchgear is a combined structure, and the basic frame is assembled from C-type steel; Each cabinet body of MNS combined low-voltage switchgear is divided into three chambers, namely horizontal bus chamber (at the rear of the cabinet), drawer chamber (at the front of the cabinet), and cable chamber (at the lower part of the cabinet or at the right in front of the cabinet).

操作步驟：

Operation steps:

a：在遠(yuǎn)程、就地旋紐旁邊的有一小孔(右下方)，用小螺絲刀伸進(jìn)小孔向下壓擋板。

a: There is a small hole (lower right) next to the remote and local knob. Use a small screwdriver to extend into the small hole and press the baffle down.

b：在一次關(guān)左側(cè)有一小孔，同樣用另一小螺絲刀伸進(jìn)去頂開(kāi)。

b: There is a small hole on the left side of one-time closing. Similarly, use another small screwdriver to push it in and open it.

c：兩螺絲刀同時(shí)用力解鎖，打開(kāi)抽屜門(mén)。

c: Unlock with two screwdrivers at the same time and open the drawer door.

d：手動(dòng)調(diào)整一次開(kāi)關(guān)前面連桿(有時(shí)往往打不開(kāi)，就是因?yàn)樵撎庍B桿卡住)斷開(kāi)主開(kāi)關(guān)。

d: Manually adjust the connecting rod in front of the primary switch (sometimes it can not be opened because the connecting rod is stuck) to disconnect the main switch.

e：再確認(rèn)主開(kāi)關(guān)下方的機(jī)械連桿是否已釋放到位，若沒(méi)到位，活動(dòng)一下即可。

e: Then confirm whether the mechanical connecting rod under the main switch has been released in place. If not, move it.

f：旋開(kāi)二次開(kāi)關(guān)按鈕，抽出位置

f: Unscrew the secondary switch button to the safe extraction position

g：抽出抽屜，然后復(fù)位，恢復(fù)送電。

g: Pull out the drawer, reset it and restore power transmission.

h：只有一次開(kāi)關(guān)與二次開(kāi)關(guān)嚙合到位抽屜才能抽拉自如、開(kāi)關(guān)才能旋轉(zhuǎn)流暢。

h: Only when the primary switch and the secondary switch are engaged in place, the drawer can be pulled freely and the switch can rotate smoothly.
