Description

抗突波繞線可熔斷電阻保險絲Anti-surge winding fusible resistor fuse

本創作係關於一種保險絲電阻器，尤指一種具有隔熱結構及第二熔絲的抗突波繞線可熔斷電阻保險絲。The present invention relates to a fuse resistor, and more particularly to an anti-surge winding fusible resistance fuse having a heat insulating structure and a second fuse.

在電子電路中時常使用保護電路來將故障的電路與其他電路隔離。例如，保護電路可以用來避免電子汽車引擎控制器中電路模組的級聯故障(cascade failure)。保護電路亦可用來對抗更嚴重的問題，像是因電力供應電路故障所引起的火災。Protection circuits are often used in electronic circuits to isolate faulty circuits from other circuits. For example, the protection circuit can be used to avoid cascade failures of circuit modules in an electronic vehicle engine controller. Protection circuits can also be used to combat more serious problems, such as fires caused by power supply circuit failures.

第二熔絲為上述保護電路的其中一種類型。第二熔絲的作用與典型的玻璃管保險絲(glass fuse)類似。意即，在正常運作狀態下，保險絲的行為與短路(short circuit)相同，而在故障狀態下該保險絲的行為便像是開路(open circuit)一般。當第二熔絲的溫度超過特定溫度時，該第二熔絲便在這兩種運作模式之間轉換。為了促成這些模式，第二熔絲會含有一傳導元件，像是可熔金屬絲、一組金屬接點，或是一組已焊接的金屬接點，其可以從一傳導狀態切換成一非傳導狀態。其設計中亦可整合一感應元件，該感應元件的物理狀態會隨該感應元件的溫度而改變。例如，該感應元件可能相當於一種低熔點的金屬合金或是一離散熔融的有機化合物，其於致動溫度時會熔化。當感應元件改變狀態時，傳導元件便會藉由實際中斷電力傳導路徑的方式從傳導態切換成該非傳導態。The second fuse is one of the above types of protection circuits. The second fuse acts like a typical glass fuse. That is, under normal operating conditions, the fuse behaves the same as a short circuit, and in the fault state, the fuse behaves like an open circuit. When the temperature of the second fuse exceeds a certain temperature, the second fuse switches between the two modes of operation. To facilitate these modes, the second fuse may contain a conductive element, such as a fusible wire, a set of metal contacts, or a set of soldered metal contacts that can be switched from a conductive state to a non-conductive state. . A sensing element can also be integrated in the design, the physical state of the sensing element changing with the temperature of the sensing element. For example, the sensing element may correspond to a low melting metal alloy or a discrete molten organic compound that melts at the actuation temperature. When the sensing element changes state, the conducting element switches from the conductive state to the non-conducting state by actually interrupting the power conduction path.

在運作中，電流會流過保險絲元件。一旦感應元件達到指定的溫度，其狀態會改變而使傳導元件從傳導態切換成該非傳導態。In operation, current flows through the fuse element. Once the sensing element reaches the specified temperature, its state changes to switch the conducting element from the conducting state to the non-conducting state.

現有第二熔絲的缺點在於第二熔絲的設置期間須非常小心，避免該第二熔絲達到感應元件改變狀態的溫度，此外也必須避免熱能喪失，熱能不夠集中或喪失過多，使第二熔絲無法準確判斷啟動時間。A disadvantage of the existing second fuse is that during the installation of the second fuse, care must be taken to avoid the temperature at which the second fuse reaches the state in which the sensing element changes. In addition, heat energy loss must be avoided, heat energy is not concentrated or excessively lost, so that the second The fuse cannot accurately determine the start-up time.
