Embodiment 1

[0027] A changeover switch, comprising two groups of circuit breakers, volume variable parts and transmission parts; the two groups of circuit breakers are provided with a toggle piece 15, and the two groups of circuit breakers realize switching by rotating the respective toggle pieces 15. Closing action: the volume visible part is configured to increase in volume after being heated, and then drive the two groups of circuit breakers to rotate by driving the transmission part and make the two groups of circuit breakers realize the opening action . The circuit breaker realizes the opening and closing operation through the rotation of the toggle piece 15. Since the structure of the circuit breaker and the toggle piece 15 is a conventional technical means for those skilled in the art, so this embodiment will not repeat them.

[0028] like figure 1 as well as figure 2 As shown, the variable volume component includes a housing 11 , a phase-change expansion substance 12 and a pist...

Embodiment 2

[0035] A transfer switch, including two groups of circuit breakers, volume variable parts and transmission parts; the two groups of circuit breakers are equipped with toggle parts, and the two groups of circuit breakers realize opening and closing by rotating the respective toggle parts Action: the volume-visible component is configured to increase in volume after being heated, and then drive the transmission component to drive the toggles of the two groups of circuit breakers to rotate and enable the two groups of circuit breakers to realize the opening action.

[0036] like figure 1 as well as figure 2 As shown, the variable volume component includes a housing 11, a phase-change expansion substance 12, and a piston 13. The inner wall of the housing 11 is provided with two chambers that are independent and isolated from each other. The piston 13 is connected to the inner wall of the chamber. Sliding and sealing connection, a sealed cavity is formed between the piston 13, th...

Abstract

The invention provides a change-over switch. The change-over switch comprises two groups of circuit breakers, a volume variable component and a transmission component, the two groups of circuit breakers are respectively provided with tpoking pieces, and the two groups of circuit breakers respectively realize switching-on and switching-off actions by rotating the respective poking pieces; and the volume variable component is configured to drive the poking pieces of the two groups of circuit breakers to rotate by driving the transmission part after the volume is increased after the volume variable component is heated, and enable the two groups of circuit breakers to realize switching-off action. Through the characteristic that the volume of the volume variable component is increased after the volume variable component is heated, the poking pieces of the two groups of circuit breakers are driven to rotate, and the two groups of circuit breakers are opened, so that the change-over switch can be automatically opened under a high-temperature condition; the problems that accidents such as fire disasters or electric shocks are caused by high-temperature switching-on, and the change-over switch cannot be effectively controlled to perform switching-off action in time due to communication faults or data transmission errors of the temperature sensor and the control system are avoided.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to a transfer switch. Background technique [0002] A transfer switch is a switching device that can be used for two or more power sources or load conversions. The automatic transfer switch is widely used in various places that require uninterrupted power supply. It realizes the automatic transfer of the load line between the two power sources to ensure the reliability of the user's power supply. In the existing transfer switch, a temperature sensor is used to monitor the operating temperature. When the operating temperature is too high, the transfer switch is remotely controlled to open, thereby avoiding accidents such as fire or electric shock. However, the temperature sensor is used to monitor and remotely control the transfer switch to open at high temperature, which has the problem of being unable to effectively control the transfer switch to perform the opening ac...
