Description

Technical Field

[0001] The present application relates to the field of circuit breakers, and in particular to a low-voltage switch cabinet circuit breaker that is easy to install. Background Art

[0002] High and low voltage switchgear is a type of electrical equipment used to connect high and low voltage cables. It typically consists of a cabinet and a circuit breaker trolley. Existing circuit breakers are typically mobile, meaning the trolley can be pushed into the cabinet and into its operating position.

[0003] Multiple groups of circuit breakers are generally installed side by side in high and low voltage switch cabinets. These groups of circuit breakers are simultaneously slidably connected to a set of clamping strips, which are fixed to the high and low voltage switch cabinets by bolts. Therefore, if one group of circuit breakers is damaged, the entire group of circuit breakers must be removed to replace the damaged circuit breaker. Therefore, the existing circuit breaker installation method is not convenient for workers to inspect and repair. Utility Model Content

[0004] In order to solve the problem that when one group of circuit breakers is damaged, the entire group of circuit breakers must be disassembled to replace the damaged circuit breaker, so the existing installation method of circuit breakers is not convenient for workers to inspect and repair, the present application provides a low-voltage switch cabinet circuit breaker that is easy to install.

[0005] The present application provides a low-voltage switch cabinet circuit breaker that is easy to install and adopts the following technical solution:

[0006] A low-voltage switch cabinet circuit breaker that is easy to install includes a slide rail, which is slidably connected to a slide plate. Both ends of the front of the slide plate are provided with connecting plates. Threaded rods are passed through the two connecting plates transversely. Bearings are sleeved on opposite ends of the two threaded rods. Both bearings are connected to positioning plates. A circuit breaker body is provided between the two positioning plates. Turn knobs are provided on opposite ends of the two threaded rods.

[0007] Preferably, an L-shaped plate is provided on the bottom surface of the slide plate, and the circuit breaker body is arranged on the top surface of the L-shaped plate.

[0008] Preferably, the back side of the slide rail is detachably connected to a mounting bracket via screws, and the four corners of the mounting bracket are detachably connected to mounting panels via screws.

[0009] Preferably, the four corners of the mounting panel are detachably connected to the wall of the low-voltage switch cabinet by screws.

[0010] Preferably, the four corners of the slide are detachably connected to the slide rails by screws.

[0011] In summary, this application has the following beneficial technical effects:

[0012] By rotating the two knobs, the rotation of the two knobs drives the two threaded rods to move relative to each other, and the relative movement of the two threaded rods drives the two positioning plates to move relative to each other. The two positioning plates can fix the circuit breaker body, thereby improving the stability of the circuit breaker body and preventing the internal components of the circuit breaker body from loosening when the low-voltage switch cabinet collides, thereby ensuring the service life of the circuit breaker body. The circuit breaker body is fixed by the two positioning plates, so that when the circuit breaker body is replaced or maintained in the future, the circuit breaker body can be quickly installed and disassembled without repeatedly removing screws.

[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The embodiment of the present application discloses a low-voltage switch cabinet circuit breaker that is easy to install, referring to Figure 1 and Figure 2 The two fixing plates 11 are connected to each other by a plurality of fixing plates 11, and the fixing plates 11 are connected to each other by a plurality of fixing plates 11.

[0019] Reference Figure 1 and Figure 3 The back of the slide rail 3 is detachably connected to the mounting bracket 2 by screws, and the four corners of the mounting bracket 2 are detachably connected to the mounting panel 1 by screws. The four corners of the mounting panel 1 are detachably connected to the wall of the low-voltage switch cabinet by screws, and the four corners of the slide plate 4 are detachably connected to the slide rail 3 by screws. The mounting panel 1, the mounting bracket 2, the slide rail 3 and the slide plate 4 are all detachably installed by screws, which ensures the stability of the installation of the circuit breaker body 7, and the circuit breaker body 7 is fixed by two positioning plates 11, so that when the circuit breaker body 7 is replaced or maintained in the later stage, the circuit breaker body 7 can be quickly installed and removed without repeatedly removing the screws.

[0020] The implementation principle of a low-voltage switch cabinet circuit breaker that is easy to install in an embodiment of the present application is as follows: when in use, by rotating the two knobs 8, the rotation of the two knobs 8 drives the two threaded rods 6 to move relative to each other, and the relative movement of the two threaded rods 6 drives the two positioning plates 11 to move relative to each other. The two positioning plates 11 are used to fix the circuit breaker body 7, thereby improving the stability of the circuit breaker body 7 and avoiding the loosening of internal components of the circuit breaker body 7 when the low-voltage switch cabinet collides, thereby ensuring the service life of the circuit breaker body 7. The mounting panel 1, the mounting frame 2, the slide rail 3 and the slide plate 4 are all detachably mounted by screws, thereby ensuring the stability of the installation of the circuit breaker body 7. The circuit breaker body 7 is fixed by the two positioning plates 11, so that when the circuit breaker body 7 is replaced or maintained in the later stage, the circuit breaker body 7 can be quickly installed and disassembled without repeatedly removing the screws.
