Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets, in particular to an anti-collision high-voltage switch cabinet. Background Art

[0002] The main structure of high-voltage switchgear generally includes relay room, circuit breaker room, cable room and busbar room. Due to the existence of high voltage, the high-voltage relay in the relay room needs to avoid the generation of severe vibration. When severe vibration occurs, the contact end in the relay is in contact through magnetic attraction, and the contact place is prone to friction, thereby generating arcs in an instant, which can easily cause danger. During the use of high-voltage switchgear, due to the limitations of some installation sites, it is sometimes inevitable that it will be subject to some bumps and other phenomena. For example, when it is installed outdoors or in some production workshops, it is easily disturbed by some human or external touches. The current high-voltage switchgear structure is basically a conventional shell structure, which is usually unable to deal with the vibration caused by external collisions. Once the cabinet shell encounters severe external bumps during use, the internal relay is prone to high-temperature arcs, thereby causing fires. Utility Model Content

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Reference Figure 1-5 An embodiment of the utility model provides an anti-collision high-voltage switch cabinet, including a cabinet body 1, on which an openable door panel is arranged, and the door panel is omitted in the figure. In addition, the cabinet body 1 also includes the following parts:

[0029] An installation part 2, the installation part 2 is located in the relay room of the cabinet 1, and the high-voltage relay is used to be completely arranged on the installation part 2;

[0030] The shock absorber 3 is connected between the mounting portion 2 and the cabinet 1, so that a soft connection effect is formed between the cabinet 1 and the mounting portion 2;

[0031] A fixing assembly 4, which is used to form a fixed connection or release a fixed connection between the mounting portion 2 and the cabinet 1, and is electrically driven;

[0032] A vibration sensor is used to detect the occurrence of vibration. For example, a model such as SE930 or SE990 can be used. It is fixedly connected to the cabinet 1, but there is no requirement for the specific setting position on the cabinet 1, which is omitted in the figure. There is an electrical signal connection relationship between the vibration sensor and the fixed component 4;

[0033] Based on the above, under normal circumstances, the fixing component 4 always keeps the mounting portion 2 and the cabinet 1 in a fixed connection state. Through the cooperation of the vibration sensor, it can directly detect whether the cabinet 1 is vibrating. When vibration is detected, the fixing component 4 releases the hard connection between the mounting portion 2 and the cabinet 1 through an electrical signal connection. Therefore, when the cabinet 1 is hit, the mounting portion 2 and the cabinet 1 only have a soft connection relationship, which can effectively avoid the amplitude on the cabinet 1 from being transmitted to the mounting portion 2, so as to reduce the high-voltage relay from being vibrated, thereby effectively preventing the arc from occurring inside it, so as to improve the safety of the entire device;

[0034] The utility model cooperates with the shock absorber 3 and the fixing assembly 4 so that under normal circumstances, the relay is equivalent to being fixed inside the cabinet 1, that is, hard-connected with the cabinet 1, so that the regulation or wiring operation during use can be convenient. When the cabinet 1 is hit, the cabinet 1 will vibrate, thereby releasing the hard connection between the installation part 2 and the cabinet 1, so as to effectively protect the high-voltage relay through the soft connection between the two, so as to better cope with the occurrence of the cabinet 1 being hit during use.

[0035] Further, see Figure 2-5The fixing component 4 includes a resistance member 401 elastically connected to the cabinet 1, and the resistance member 401 is a plurality of resistance members and is a hard structure for resisting the mounting portion 2. The fixing component 4 also includes a driving element 402 for driving the resistance member 401 to move, and the driving element 402 is connected to the electrical signal of the vibration sensor; when the plurality of resistance members 401 are in normal state, they are elastically resisted against the mounting portion 2 together, thereby pressing the mounting portion 2 tightly, so that a relatively fixed effect is achieved between the mounting portion 2 and the cabinet 1. When the driving element 402 is working, the resistance member 401 is controlled to overcome the elastic force and move away from the mounting portion 2, thereby separating from the mounting portion 2 to release the resistance effect, thereby releasing the hard connection effect between the mounting portion 2 and the cabinet 1. Through the fixing component 4 of this structure, it has a fast response speed when working, so that it can better quickly release the hard connection between the mounting portion 2 and the cabinet 1 when the vibration signal is generated.

[0036] Further, see Figure 2-5 Regarding the working mode of the driving element 402, the resistance member 401 has a magnetic attraction feature, such as the resistance member 401 can adopt a structure such as an iron block, and the driving element 402 includes an electromagnet 402a, which is fixedly connected to the cabinet 1; through the adsorption of the electromagnet 402a, when it is powered on, the suction force formed will immediately act on the resistance member 401, so that the resistance member 401 overcomes the elastic force and moves in the direction of the electromagnet 402a. The cooperation of the electromagnet 402a structure makes the structure and working mode of the driving element 402 simpler, and can provide a better response speed; in this scheme, the electrical signal connection between the electromagnet 402a and the vibration sensor can be realized by connecting using a single-chip microcomputer controller, so as to achieve the corresponding linkage effect.

[0037] Further, see Figure 2-5 The utility model also includes a support frame 5, which is fixedly connected to the cabinet 1. The resistance member 401 slides with the support frame 5, so that a movable arrangement can be formed on the cabinet 1. A spring assembly 6 is also connected between the resistance member 401 and the support frame 5 to achieve an elastic connection relationship relative to the cabinet 1; through the sliding relationship of the resistance member 401 relative to the cabinet 1, it can always be located on the same path when moving, so that it will be more stable when it abuts against the installation part 2, so as to ensure the stability requirement when the installation part 2 and the cabinet 1 are hard-connected.

[0038] Further, see Figure 3-5 Regarding the distribution relationship of the plurality of resisting members 401, specifically, the plurality of resisting members 401 are symmetrically distributed on the support frame 5, and at least two force-bearing plates 7 are symmetrically arranged on the mounting portion 2, the force-bearing plates 7 and the mounting portion 2 can be integrally formed, and the two force-bearing plates 7 are respectively used to contact the two symmetrically distributed resisting members 401, such as Figure 4As shown, the two resistance members 401 can move closer to each other or away from each other when they are active. When they move away from each other, they respectively form resistance against the two force-bearing plates 7, thereby achieving the effect of tightening the mounting part 2. The two force-bearing plates 7 are symmetrically distributed to keep the mounting part 2 more evenly stressed when receiving the resistance force from the resistance members 401, thereby further improving the stability of the mounting part 2 when it is fixed.

[0039] Further, see Figure 5 The resistance member 401 is in a columnar structure and has a limit position 8 thereon. A docking hole 9 corresponding to the resistance member 401 is constructed on the force-bearing plate 7, which is used to accommodate the resistance member 401. Through the cooperation of the docking hole 9, when the resistance is formed, the resistance member 401 is accommodated in the docking hole 9, and the limit position 8 abuts against the force-bearing plate 7. Based on this structural design, the firmness of the mounting portion 2 when being fixed can be further improved, so that even when the resistance force is insufficient, the force-bearing plate 7 will not detach from the resistance member 401, thereby achieving the effect of connection protection.

[0040] Further, see Figure 2-5 Regarding the distribution of the shock absorbers 3, there are multiple shock absorbers 3, which are evenly distributed on the two force-bearing plates 7 and distributed in the horizontal and vertical directions; this distribution method can improve the stability of the soft connection between the mounting portion 2 and the cabinet 1, thereby ensuring the soft connection effect while the mounting portion 2 will not form a large swing or displacement on the cabinet 1, so as to prevent the mounting portion 2 from causing bumps inside the cabinet 1.

[0041] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
