Description

Technical Field

[0001] The utility model relates to the technical field of combined electrical appliances, in particular to the field of combined electrical appliance bus position, and specifically refers to a combined electrical appliance bus position deviation observation device. Background Art

[0002] Gas-insulated metal switchgear is also called combined electrical equipment. Combined electrical equipment is an important part of the power system. It consists of circuit breakers, disconnectors, current transformers, grounding switches, busbars and other parts. Through optimized combination, flanges are used externally and conductors are used internally for connection. In combined electrical equipment, the busbar is a key component for power transmission and distribution. Its stability and safety are crucial to the overall operation of the power system. However, during operation, the busbar may expand or contract due to the influence of temperature changes, mechanical vibrations, electromagnetic forces and other factors, causing the busbar to deviate. Busbar deviation may not only affect the stable operation of the power system, but also pose a threat to the safety of equipment and personnel.

[0003] Traditional busbar offset detection methods usually rely on power outages and manual measurements. This method not only consumes a lot of manpower and time, but also fails to reflect the busbar offset in real time, making it difficult to provide timely and accurate maintenance basis for operation and maintenance personnel. When the busbar expands or contracts, the operation and maintenance personnel are very likely to be unable to discover it in time and take corresponding measures, which will pose a hidden danger to the safety of the combination electrical appliances. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a combined electrical appliance bus position deviation observation device, which can directly observe the expansion and contraction of the combined electrical appliance bus, so that the staff can easily observe the bus deviation phenomenon, and thus make corresponding maintenance plans to avoid accidents.

[0005] The utility model is realized through the following technical scheme, and provides a combined electrical appliance bus position deviation observation device, comprising a bus support frame for supporting the bus, a scale extending along the axial direction of the bus is installed on the bus support frame, a pointer is fixed on the bus, and the pointer extends to the scale.

[0006] The utility model installs the busbar by arranging a busbar support frame, and a scale is fixed on the busbar support frame so that the scale does not move with the thermal expansion and contraction of the busbar, and a pointer is fixed on the busbar. When the busbar expands and contracts, the pointer moves with the busbar. At this time, the position where the pointer points to the scale changes, so that the staff can more intuitively observe the displacement of the busbar caused by the thermal expansion and contraction, and thus make corresponding maintenance plans to avoid accidents.

[0007] As an optimization, the pointer includes a mounting plate extending in the horizontal direction and a graduated needle extending in the vertical direction. The mounting plate is connected to the busbar, and the graduated needle is fixed to the end of the mounting plate away from the busbar. The graduated needle is located outside the scale. The setting of this optimization scheme facilitates the installation of the pointer, and the graduated needle is located outside the scale, which is convenient for the staff to observe the displacement of the busbar.

[0008] As an optimization, a clamp for installing the pointer is provided on the busbar, and the clamp includes a left clamp and a right clamp, which are fixed by bolts, and the busbar is located between the left clamp and the right clamp. The setting of this optimization scheme is convenient for installing the needle by the clamp, and the left and right clamps clamp the busbar in the middle, so that the clamp is fixed on the busbar, so that the pointer moves with the busbar.

[0009] As an optimization, an arc pad is provided between the clamp and the busbar, the inner wall of the arc pad is in contact with the busbar, and the outer wall of the arc pad is in contact with the inner wall of the clamp. The setting of this optimization scheme can prevent the clamp from damaging the busbar, and at the same time make the clamp more firmly fixed to the busbar.

[0010] As an optimization, the clamp bolt is connected with a connecting plate, and the pointer is fixed on the connecting plate. The setting of this optimization scheme facilitates the connection of the pointer, and the connecting plate can be directly connected to the connecting ear of the clamp by bolts, which is convenient for installation.

[0011] As an optimization, two pointers are provided, and the two pointers are respectively located on the left and right sides of the busbar. The setting of this optimization scheme is convenient for the staff to observe. The staff can observe the displacement of the busbar standing on both sides of the busbar, and at the same time, by observing the displacement of the pointers on both sides on the scale, two data can be obtained, making the observation result more accurate.

[0012] The beneficial effect of the utility model is that when the busbar contracts or expands due to external factors, the utility model will move with the busbar, and the staff can observe this situation through the position changes of the pointer and the scale. The utility model can help equipment operation and maintenance personnel to easily observe the real-time situation of the busbar, make corresponding maintenance plans, and avoid the occurrence of misjudgments.

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0019] like Figures 1 to 3 The utility model shown is a device for observing the position deviation of a combined electrical appliance busbar, comprising a busbar support frame 1 for supporting the busbar. The busbar support frame is a prior art. The busbar support frame comprises a lower frame body and a supporting ring. The busbar is supported in the supporting ring. The busbar extends in the front-to-back direction. The lower end of the supporting ring is fixedly connected to the lower frame body by bolts. A scale 6 extending along the axial direction of the busbar is installed on the busbar support frame. The lower end face of the scale 6 is fixedly connected to the upper end face of the lower frame body of the busbar support frame 1. The scale is provided with scales arranged in the front-to-back direction.

[0020] A pointer 5 is fixedly connected to the busbar, and the pointer extends to the scale 6. The pointer includes a mounting plate 51 extending in the horizontal direction. The mounting plate 51 extends in the left-right direction. The inner end of the mounting plate is connected to the busbar, the inner end is the end close to the busbar, and the outer end is the end away from the busbar. The mounting plate is located above the lower frame of the busbar support frame. The mounting plate 51 extends to the outside of the scale. The pointer also includes a scale needle 52 extending in the vertical direction. The scale needle 52 extends in the vertical direction. The scale needle 52 is fixed to the end of the mounting plate 51 away from the busbar, that is, the upper end of the scale is fixed to the outer end of the mounting plate 51. The scale needle 52 is located on the outside of the scale 6, and the lower end of the scale needle extends to the outside of the scale on the scale. There is a small gap between the outer end surface of the scale 6 and the inner end surface of the scale needle 51 to facilitate the movement of the scale needle. Two pointers are provided, and the two pointers are respectively located on the left and right sides of the busbar.

[0021] The busbar is provided with a clamp 2 for installing the pointer 5. The clamp is of prior art and includes a left clamp 21 and a right clamp 22. The left clamp 21 and the right clamp 22 are fixedly connected by bolts. The busbar is located between the left clamp 21 and the right clamp 22. The bolted connection points of the left clamp 21 and the right clamp 22 are respectively located directly above and directly below the busbar. An arc pad 3 is provided between the clamp and the busbar. The arc pad is made of rubber material. The inner wall of the arc pad is in contact with the busbar, and the outer wall of the arc pad 3 is in contact with the inner wall of the clamp. The clamp can be firmly fixed to the busbar by tightening the bolts.

[0022] The clamp 2 is bolted to a connecting plate 4. A connecting plate is provided on each of the left and right clamps. The connecting plate 4 includes a horizontal plate and a vertical plate. The vertical plate extends in a vertical direction. Bolt holes extending in left and right directions are provided on the vertical plate. The bolts connecting the left and right clamps pass through the bolt holes on the vertical plate. The inner end of the vertical plate fits with the outer wall of the connecting ear at the lower end of the clamp. The bolt passes through the right vertical plate, the right clamp, the left clamp, the left vertical plate, and the nut from right to left in sequence.

[0023] The horizontal plate extends in the left-right direction, and the left end of the horizontal plate is fixedly connected to the lower end of the vertical plate. The horizontal plate and the vertical plate are integrally formed. The inner end of the mounting plate 51 of the pointer 5 is fixedly connected to the outer end of the horizontal plate by bolts, so that the pointer 5 is fixedly connected to the connecting plate 4.

[0024] During use of this embodiment, when the busbar expands and contracts due to thermal expansion and contraction, the busbar will drive the clamp 2 to move in the front-to-back direction. The displacement of the clamp 2 drives the connecting plate 4 to move in the same manner, thereby causing the pointer 6 to move. When the pointer 6 moves, the position of the pointer's scale needle 52 on the scale 6 will change. The staff can observe the thermal expansion and contraction of the busbar based on the position change of the scale needle 52 on the scale 6, and thus make corresponding maintenance plans to avoid accidents.
