Description

Technical Field

[0001] The utility model relates to the technical field of switchgear, and particularly relates to a circuit breaker panel. Background Art

[0002] Most of the existing draw-out circuit breaker panels are composed of a metal panel and a plastic panel. The advantage of this kind of circuit breaker panel is its beautiful appearance, while the disadvantage is that the plastic panel needs to be processed by mold opening and its overall strength is relatively low. This combined panel is suitable for conventional power distribution projects, but not for the nuclear power field. Nuclear power products need to meet the requirements of long-term thermal aging operation. Due to the aging mechanism of the plastic material, continuous operation at high temperature is likely to cause permanent deformation, resulting in quality problems such as shedding. At the same time, when the internal combustion arc fault test is carried out in the circuit breaker handcart chamber, the plastic panel cannot play a role in buffering energy under high temperature and high pressure, and will shed when subjected to thermal shock. At this time, the air pressure directly impacts the middle door of the cabinet, which is likely to cause the test to fail and even lead to safety accidents. Content of the Utility Model

[0003] The purpose of the utility model is to provide a circuit breaker panel. By changing the panel of the traditional circuit breaker into an integral metal structure, the problem of heat-induced shedding is avoided. At the same time, when impacted, the panel plays a role in buffering energy and avoids the occurrence of safety accidents.

[0004] To achieve the above purpose, the utility model provides a circuit breaker panel, which includes a panel body. The panel body is an integral metal structure, which includes an outer panel surface fixed to the frame and an installation surface located in the middle of the outer panel surface and protruding from the outer panel surface; the installation surface is provided with a first installation hole for installing a control button and a second installation hole for installing an instrument.

[0005] After adopting the above structure, by changing the traditional circuit breaker panel into an integral metal structure, the problem of heat-induced shedding is avoided. At the same time, when the panel of the circuit breaker is impacted, it will not shed due to the impact, making the panel play a role in buffering energy and avoiding the occurrence of safety accidents.

[0006] In order to strengthen the strength of the panel body, and at the same time facilitate processing and improve aesthetics, a transverse strengthening structure and a longitudinal strengthening structure are provided on the panel body. The transverse strengthening structure includes a plurality of first rolling grooves arranged on the installation surface and horizontally, and the first rolling grooves are recessed towards the inside of the circuit breaker.

[0007] In order to strengthen the strength of the position of the first installation hole, the transverse strengthening structure further includes a second rolling groove arranged in a ring around the first installation hole, and the second rolling groove is recessed towards the inside of the circuit breaker.

[0008] In order to effectively avoid the shedding of the button when thermal aging or thermal shock occurs, the control button is made of aluminum alloy.

[0009] In order to further strengthen the strength of the position of the first mounting hole, a reinforcing flange is provided on one side of the first mounting hole inside the circuit breaker.

[0010] In order to longitudinally strengthen the panel body and achieve structural balance and simultaneous strengthening on both sides, the longitudinal strengthening structure includes longitudinal reinforcing ribs arranged on the outer panel surface longitudinally. There are two longitudinal reinforcing ribs, which are respectively located on both sides of the mounting surface.

[0011] For the convenience of processing and for aesthetic purposes, the longitudinal reinforcing ribs are longitudinally arranged on the outer panel surface and are the third roll-formed grooves that are recessed towards the outside of the circuit breaker.

[0012] In order to strengthen the longitudinal strengthening effect, the longitudinal reinforcing ribs include a rib plate structure fixed on the inner side of the outer panel surface of the circuit breaker and extending longitudinally.

[0013] In order to improve the longitudinal strengthening effect, the rib plate structure includes a corrugated plate welded on the outer panel surface and extending longitudinally. A protective cover is sleeved outside the corrugated plate, and the protective cover is welded on the outer panel surface.

[0014] In order to achieve quick positioning and installation, flanges that are buckled on the frame are respectively provided at the top and both sides of the outer panel surface. Among them, hooks that cooperate with the positioning grooves at the top of the frame are provided on the top flange, and through holes that cooperate with the threaded holes at the bottom of the frame are provided at the bottom of the outer panel surface.

[0015] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0016] A circuit breaker panel of the present utility model solves the technical problem that the circuit breaker panel in the prior art is prone to separation and falling off when heated and impacted. By changing the traditional panel combination structure to an integral metal structure, the present utility model avoids the problem of falling off due to heating. At the same time, when impacted, the panel plays an energy buffering role and avoids the occurrence of safety accidents. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0024] The following further elaborates the present utility model in conjunction with the attached drawings.

[0025] The orientations involved in this specification are based on the orientation when a circuit breaker panel of the present utility model is working properly, without limiting its orientation during storage and transportation, only representing the relative positional relationship and not the absolute positional relationship.

[0026] Embodiment 1:

[0027] As Figure 1 、 Figure 2 and Figure 3 collectively described, a circuit breaker panel is installed on the frame 2 of a handcart circuit breaker, including a panel body 1. The panel body 1 is an integral metal structure. In this embodiment, it is a sheet metal structure, formed by sheet metal bending and partial seam welding. The integral metal structure increases the strength of the panel body and avoids separation caused by high temperature or impact.

[0028] The panel body 1 includes an outer panel surface 11 fixed to the frame 2 and a mounting surface 12 located in the middle of the outer panel surface 11 and protruding from the outer panel surface 11. Flangings 111 buckled on the frame 2 are respectively arranged at the top and both sides of the outer panel surface 11. Among them, a hook 112 cooperating with the top positioning groove of the frame 2 is arranged on the top flanging 111, and a through hole 113 cooperating with the bottom threaded hole of the frame 2 is arranged at the bottom of the outer panel surface 11. First mounting holes 121 for installing control buttons and second mounting holes 122 for installing instruments are arranged on the mounting surface 12. Changing the traditional plastic control buttons to aluminum alloy material effectively avoids the buttons from falling off when suffering from thermal aging or thermal shock.

[0029] During installation, hook the hook 112 into the positioning groove of the frame 2, then buckle the flanging 111 on the periphery of the frame 2 to achieve rapid positioning. Finally, pass a bolt through the through hole 113 and screw it into the frame 2 to achieve rapid fixation of the outer panel surface 11.

[0030] In order to improve the strength of the circuit breaker panel, a transverse strengthening structure 3 and a longitudinal strengthening structure 4 are provided on the panel body 1. The transverse strengthening structure 3 and the longitudinal strengthening structure 4 are arranged horizontally and vertically respectively, so as to strengthen the panel body 1 horizontally and vertically, improve its strength and avoid deformation.

[0031] The transverse strengthening structure 3 and the longitudinal strengthening structure 4 can be back ribs welded to the back of the panel body 1. However, welding is likely to damage the panel body 1 and is not aesthetically pleasing. Therefore, in this embodiment, the transverse strengthening structure 3 includes a number of first rolling grooves 31 arranged horizontally on the mounting surface 12. In this embodiment, for reasonable layout, six first rolling grooves 31 are provided, which are respectively arranged at the upper and lower ends of the mounting surface 12, with three at each end. In actual application, other numbers can be set according to the area of the mounting surface 12, and this embodiment does not limit this.

[0032] The first rolling groove 31 is recessed into the circuit breaker. Since the mounting surface 12 protrudes from the outer panel surface 11, if the first rolling groove 31 continues to protrude outward, it is very likely to cause interference to some components. Therefore, in this embodiment, the first rolling groove 31 is recessed into the circuit breaker.

[0033] The first rolling groove 31 is completed by rolling. The cross-sectional shape of the first rolling groove 31 can be circular, trapezoidal or other shapes, and this embodiment does not limit this. Those skilled in the art can reasonably set its shape according to the processing status. The first rolling groove 31 changes the planar structure of the panel body 1 and plays the role of a back rib by increasing the contact area.

[0034] Since the control button is installed in the first mounting hole 121 and the control button needs to be pressed, the first mounting hole 121 needs to bear the inward pressure. In order to enhance the strength of this position, the transverse strengthening structure 3 further includes a second rolling groove 32 arranged annularly around the first mounting hole 121, and the second rolling groove 32 is recessed into the circuit breaker.

[0035] Furthermore, in order to further strengthen the strength of the position of the first mounting hole 121, a strengthening edge 5 is provided on the side of the first mounting hole 121 located inside the circuit breaker. The strengthening edge 5 can be directly punched and bent, or can be welded, and this embodiment does not limit this. Of course, the strengthening edge 5 is an optional strengthening structure and is not a necessary structure.

[0036] The longitudinal strengthening structure 4 includes longitudinal strengthening ribs arranged on the outer panel surface 11 and longitudinally. There are two longitudinal strengthening ribs, which are respectively located on both sides of the mounting surface 12. In this embodiment, the longitudinal strengthening ribs are the third rolling grooves 41 longitudinally arranged on the outer panel surface and recessed outward from the circuit breaker, and the third rolling grooves 41 play the role of longitudinal strengthening ribs.

[0037] Embodiment 2:

[0038] As Figure 4 , Figure 5 and Figure 6 collectively shown, this embodiment is basically the same as Embodiment 1. The only difference is that the structure of the longitudinal stiffeners is different. In this embodiment, the longitudinal stiffeners include a rib plate structure 42 disposed on the outer plate surface on one side inside the circuit breaker and extending longitudinally. The rib plate structure 42 can be a solid steel plate. In this embodiment, in order to enhance the strengthening effect and reduce the weight at the same time, the rib plate structure 42 includes a corrugated plate 421 welded to the outer plate surface 11 and extending longitudinally. A protective cover 422 is disposed outside the corrugated plate 421, and the protective cover 422 is welded to the outer plate surface. The longitudinal anti-deformation ability can be enhanced through the corrugated plate 421, and the protective cover 422 protects the corrugated plate 421 to prevent dust from falling.

[0039] For the embodiment of Embodiment 2, it is necessary to reasonably avoid the internal structure of the frame 2 to prevent the rib plate structure 42 from interfering with the internal components.

[0040] A circuit breaker panel of the present utility model solves the technical problem in the prior art that the circuit breaker panel is prone to separation and falling off when heated and impacted. By changing the panel of the traditional circuit breaker into an integral metal structure, the present utility model avoids the problem of falling off when heated or impacted. At the same time, when impacted, the circuit breaker panel plays an energy buffering role, avoiding the occurrence of safety accidents.

[0041] Certainly, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present utility model should also fall within the protection scope of the present utility model.
