Problems solved by technology

[0004] The thermal tripping structure is often used in the surge protector, which collects the temperature change signal of the functional components in the surge protector. When an abnormal temperature rise occurs, it will cause the special components in the thermal tripping Its temperature rises synchronously to produce physical changes, which cause the breakage of components that originally had a breakage tendency
The existing thermal trip structure needs to be attached to the functional parts, but at the same time, in order to have a better breaking effect, its volume or range of motion is relatively large, and an independent power body is provided externally to provide a detachment tendency, so it cannot be applied for small installation space

Embodiment 1

[0061] A thermal tripping structure, including a power body 1 and a conductor 2, the conductor 2 is a conductor structure including an input end and a connection end, and the power body 1 arranged inside the conductor 2 makes the conductor 2 have Out of the movement trend of the circuit; at least one of the input end and the output end of the conductor 2 is connected to the external conductor through a low melting point conductive material, and the low melting point conductive material loses the restriction on the conductor 2 after being melted by heat.

[0062] In the existing thermal tripping structure, in order to achieve instant breaking effect, it is usually arranged close to the functional components, so that the thermal signal can quickly reach the receiving structure. The so-called thermal signal is the way of heat conduction through the medium, which causes the temperature of the receiving structure to rise. Due to the change of temperature, the physical form of the sp...

Embodiment 2

[0070] This embodiment also discloses a thermal tripping structure, which specifically includes a power body 1 and a conductor 2. The conductor 2 is a conductor structure including an input end and a connection end. The power body 1 arranged inside the conductor 2 makes the The conductor 2 has a tendency to move away from the circuit; the access end of the conductor 2 is connected to the external conductor through a low melting point conductive material, and the low melting point conductive material loses the restriction on the conductor 2 after being melted by heat.

[0071] Both the power body 1 and the conductor 2 are connected to the same fixed structure, the conductor 2 is rotationally connected to the fixed structure, and the power body 1 is flexibly connected to the fixed structure and can move along a straight line; The rotation axis is vertical, and one end of the power body 1 is attached to the end of the conductor 2 away from the rotation axis, and the space angle be...

Embodiment 3

[0075] This embodiment is optimized and limited on the basis of the above-mentioned embodiment 1, the conductor 2 is a rotatable structure, the power body 1 is a torsion spring structure arranged on the rotating installation position of the conductor 2, and the power body 1 continues to provide electrical conductivity. Torsional force of body 2 towards the tripping direction.

[0076] The power body 1 includes a main body and a spring arranged in the main body. When the electrical conductor 2 is fixed to an external conductor through a low melting point conductive material, the spring is compressed between the main body and the fixed structure.

[0077] The conductor 2 is a metal sheet bending structure, and the conductor 2 is provided with a through groove for placing the power body 1 , and the end of the through groove away from the rotating shaft is a slope that fits and drives the power body 1 .

[0078] The thermal tripping structure in this embodiment also includes a fee...

Abstract

The invention discloses a thermal tripping structure and a surge protector thereof. A circuit breaker protection circuit acts in time after receiving an abnormal temperature rise signal, the thermal tripping structure comprises a power body and an electric conductor, the electric conductor is of a conductor structure comprising an input end and an output end, and the electric conductor has a movement trend of being separated from the circuit through the power body arranged in the electric conductor; and at least one of the input end and the output end of the electric conductor is connected with an external conductor through a low-melting-point conductive material, and the low-melting-point conductive material loses limitation on the electric conductor after being heated and melted. The power body is arranged in the electric conductor, the size is small, installation is easy, the power body can directly act on the electric conductor, and stability is high.

Description

technical field [0001] The invention belongs to the technical field of lightning protection equipment, and in particular relates to a thermal tripping structure and a surge protector adopting the structure. Background technique [0002] Surge protector, also called lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. In the low-voltage power distribution system, when a peak current or voltage suddenly occurs in the electrical circuit or communication line due to external interference, the surge protector can conduct the shunt in a very short time, such as the overvoltage caused by lightning, so as to avoid Surge damage to other equipment in the circuit. [0003] In order to prevent the internal functional parts from overheating and igniting in the surge protector, a tripping mechanism is usually integrated. The so-called tripping mechanism is an important part of the operating s...
