Description

微型斷路器雙獨立迴路機構 Miniature Circuit Breaker Double Independent Circuit Mechanism

本創作係關於一種微型斷路器雙獨立迴路機構。 This creation is about a miniature circuit breaker double independent circuit mechanism.

微型斷路器是一種保護電器的重要元件,其主要是作為短路保護和防止嚴重超載,能夠應用於配線上使用的總開關與分電流控制開關,在工業機械上的馬達負載線路保護也會使用斷路器作為保護裝置之一,當斷路器偵測到短路、漏電或嚴重超載等問題時,斷路器能夠立即跳脫來保護線路及電器。 The miniature circuit breaker is an important component to protect electrical appliances. It is mainly used as short-circuit protection and to prevent severe overload. It can be applied to the main switch and partial current control switch used on the wiring. It will also be used to protect the motor load circuit on industrial machinery. As one of the protection devices, when the circuit breaker detects problems such as short circuit, leakage or severe overload, the circuit breaker can trip immediately to protect the circuit and electrical appliances.

微型斷路器其中有一種為雙迴路微型斷路器,是採用兩個扭簧加上壓縮彈簧,並結合復歸桿、支持座與可動子等元件所構成的機構以同步動作,但具有以下的問題: One of the miniature circuit breakers is a double-circuit miniature circuit breaker, which uses two torsion springs plus a compression spring, combined with a mechanism composed of a return rod, a support seat and a movable member to operate synchronously, but it has the following problems:

1.支持座與可動子以扭簧結合後套入主支點上,但因為扭簧施力非直線,所以投入時可動子無法每次平整地與接觸子接點嚙合,造成接觸不良和接觸壓力不穩定而讓溫度升高。 1. The support seat and the mover are combined with a torsion spring and inserted into the main fulcrum, but because the torsion spring exerts a non-linear force, the mover cannot mesh with the contacts of the contactor every time when it is put in, resulting in poor contact and unstable contact pressure And let the temperature rise.

2.復歸桿套入支持座的支點,復歸桿另一支腳再與支持座的支點扣合,但復歸桿與支持座裕度較大,使復歸桿有翻轉的疑慮,造成掛金無法固定,跳脫形成不穩定,影響短路特性和跳脫特性。 2. The return rod is inserted into the fulcrum of the support seat, and the other leg of the return rod is then buckled with the fulcrum of the support seat, but the return rod and the support seat have a large margin, which makes the return rod have the doubt of turning over, resulting in the hanging gold cannot be fixed, Tripping causes instability, affecting short-circuit characteristics and tripping characteristics.

3.復歸桿固定在支持座的另一支點上,與機構支撐點不一致,且支持 座的另一支點遠離於機構支撐點,所以復歸桿旋轉角度大、跳脫行程大,兩合金板彎曲行程無法滿足,讓跳脫行程不穩定。 3. The return rod is fixed on another fulcrum of the support seat, which is inconsistent with the support point of the mechanism, and the support The other fulcrum of the seat is far away from the support point of the mechanism, so the rotation angle of the return lever is large, and the tripping stroke is large, and the bending stroke of the two alloy plates cannot meet the requirements, making the tripping stroke unstable.

4.機構以壓縮彈簧驅動,因為壓縮量過大且偏向底座,使機構動作容易翻轉,造成動作不穩定。 4. The mechanism is driven by a compressed spring. Because the amount of compression is too large and it is biased towards the base, the movement of the mechanism is easy to overturn, resulting in unstable movement.

上述的各項問題,會讓斷路器的機構動作不穩定,容易造成短路試驗的絕緣耐壓不良,讓短路容量無法提升,跳脫試驗再現性差更重工費時,同時,也有機構組立困難和組立成本過高的缺失。 The above-mentioned problems will make the mechanism of the circuit breaker unstable, and it is easy to cause poor insulation and withstand voltage in the short-circuit test, so that the short-circuit capacity cannot be improved, the reproducibility of the trip test is poor, and it is labor-intensive and time-consuming. At the same time, it is also difficult and costly to assemble the mechanism. Excessive missing.
