Embodiment Construction
[0028] The present application will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.
[0029] The present application provides a mechanical interlocking device for an air switch, which can ensure that the backup power connected to the other air switch is disconnected when one air switch is connected to the main power supply, so as to avoid a short circuit caused by simultaneous connection of the main power supply and the backup power supply. The device has a simple structure and is easy to operate. Compared with the traditional ATS switching method, it can avoid two air switches being switched on at the same time, which can not only improve the safety of electrical equipment, but also reduce product production costs.
[0030] see Figure 2 to Figure 8 As shown, the air switch mechanical interlock device provided in this embodiment mainly includes: a rail 10 for installing the air switch 20, a support assembly 30 i...

The invention discloses a mechanical interlocking device for an air switch of an electrical cabinet. The mechanical interlocking device comprises a clamping rail for mounting the air switch; a supporting assembly which comprises a first supporting plate, a second supporting plate and a guiding piece, wherein the left side and the right side of the first supporting plate are air switch containing positions, one end of the first supporting switch is installed on the clamping rail, and the other end of the first supporting switch extends out of the air switch; a second supporting plate which is arranged at the other end of the first supporting plate; a guide part which is arranged on the second supporting plate; a baffle assembly which comprises a sliding plate and a blocking part arranged onthe sliding plate, wherein the sliding plate is slidably installed on the guide part so as to reciprocate between every two adjacent air switches; and a resisting part which is used for resisting anoperating handle of the air switch when the sliding plate slides along the guide part so as to keep the air switch in an off state. The device is simple in structure and easy to operate, can prevent two air switches from being switched on at the same time, can improve the use safety of electric equipment, and also can reduce the production cost of products.
Description
technical field [0001] The application relates to the field of power supply and distribution equipment, in particular to an air switch mechanical interlock device. Background technique [0002] Under normal circumstances, electrical equipment is usually powered by switching between the main power supply and the backup power supply. The main power supply is generally powered by commercial power, and the backup power supply is generally powered by a gasoline generator or a diesel generator to generate electricity. In order to achieve free selection of the main power supply and the backup power supply, an ATS transfer switch is required. Such as figure 1 As shown, in the electrical equipment, the air switch QF1 for the main power supply, the air switch QF2 for the backup power supply, the ATS transfer switch, the air switch QF3 output to the electrical equipment, and the electrical equipment are connected by cables to realize Electrically interlocked. When the above equipmen...
