Description
Technical Field
[0001] The invention belongs to the technical field of traditional operating mechanism boxes of outdoor substations, and in particular relates to a traditional operating mechanism box of an outdoor substation capable of reducing a defect rate. Background Art
[0002] The substation is located at the line connection point in the power network. It is a facility used to transform voltage, exchange power, and collect and distribute electric energy. According to the layout of the substation, it can generally be divided into outdoor substations, indoor substations and underground substations. The main transformers and main high-voltage electrical equipment of the outdoor substation are arranged outdoors. This layout occupies a large area, and the electrical equipment and buildings can fully meet various distance requirements, such as electrical safety clearance, fire protection distance, etc. It has a high safety factor and is easy to operate, maintain and overhaul. It is suitable for construction in urban suburbs or rural areas.
[0003] During normal operation, the number of operations on the traditional operating mechanism box of the outdoor substation is generally carried out according to the plan (i.e. normal separation and combination) and is controllable. However, actual operating data shows that there are a certain number of unplanned (i.e. abnormal separation and combination) operations in the outdoor substation, which brings certain safety hazards to the safe operation of the outdoor substation.
[0004] During the problem-finding process, it was found that the occurrence of this situation was most likely due to defects in the traditional operating mechanism box itself, such as poor contact of the secondary circuit, power switch failure, mechanical transmission component failure, water leakage, mechanism body failure, etc. After repeated inspections, water leakage was the main cause of the mechanism box defects. Further investigation of the cause of water leakage revealed that the sealing material on the top of the mechanism box had rusted or cracked due to long years of service, causing the gap between the transmission mechanism connecting rod and the top of the mechanism box to increase, thereby causing water leakage. In order to solve the above problems, it is necessary to develop a traditional operating mechanism box for outdoor substations that can reduce the defect rate. Summary of the invention

[0020] Please understand that the operating mechanism box is a box used to store the mechanical transmission components of the substation electrical equipment (including circuit breakers, disconnectors, etc.). The substation realizes the opening and closing of the electrical equipment through the operation of the mechanical transmission components. At the same time, in the event of electrical opening and closing failure, manual opening and closing can be performed through mechanical transmission to ensure the safe and stable operation of the electrical equipment, thereby ensuring the overall normal operation of the substation.
[0021] Please understand that there are many defects in the traditional operating mechanism box of the outdoor substation and the reasons for the defects. The present invention only improves and designs the water leakage defect at the connection between the connecting rod and its top on the basis of the original structure and function.
[0022] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0023] like Figure 1 and Figure 2 As shown, the present invention provides a traditional operating mechanism box for an outdoor substation that can reduce the defect rate, including a mechanism box body 1 and a connecting rod 2 passing through the top of the mechanism box body 1, the connecting rod 2 is connected to the mechanical transmission components located inside the mechanism box body 1, this is the existing structure of the outdoor traditional operating mechanism box, and will not be elaborated here.
[0024] The top upper end of the mechanism box body 1 is fixedly connected with a waterproof cylinder 4 which is sleeved on the outside of the connecting rod 2. The waterproof cylinder 4 is coaxially arranged with the connecting rod 2. The coaxially arranged waterproof cylinder 4 will not interfere with the working condition of the connecting rod 2. A rain shield 7 is fixedly connected to the connecting rod 2 above the waterproof cylinder 4. The outer diameter of the lower end of the rain shield 7 is larger than the outer diameter of the waterproof cylinder 4. The rain shield 7 with a large outer diameter can better prevent rainwater from entering. The lower end edge of the rain shield 7 is provided with a guide cylinder 6 which is coaxially arranged with the waterproof cylinder 4. The guide cylinder 6 is used to prevent rainwater from flowing back into the waterproof cylinder 7 due to typhoons and other weather conditions. The lower end of the guide cylinder 6 is lower than the upper end of the waterproof cylinder 4. The guide cylinder 6 with a low lower end can better prevent backflow.
[0025] During specific implementation, both fixed connections can be achieved by welding. The waterproof tube 4 after fixed connection is located on the outside of the connection between the two to block the inflow of rainwater. The rain shield 7 and the guide tube 6 after fixed connection follow the connecting rod 2 to perform limited rotation (for safety reasons, the rotation of the connecting rod 2 in the mechanism box body 1 is designed with a certain rotation margin). During the process of completing various working conditions of the connecting rod 2, it always cooperates well with the waterproof tube 4 below to jointly resist the intrusion of rainwater.
[0026] The lower end of the guide tube 6 is set at least 1 cm lower than the upper end of the waterproof tube 4, and is generally set to 2 cm.
[0027] Two symmetrical limit rods 5 are provided on the inner side of the lower part of the guide tube 6. The two limit rods 5 are used to limit the rotation angle of the rain umbrella 7 and the guide tube 6 following the connecting rod 2. Specifically, the limited rotation of the rain umbrella 7 and the guide tube 6 is completed by limiting the limit rod 5 through the slide groove 12 to prevent the rotation of the two from affecting the working conditions of the connecting rod 2. The inner end of the limit rod 5 is longer than the side wall setting of the waterproof tube 4. The waterproof tube 4 is provided with two bayonet holes 11 matching the limit rod 5 settings. The waterproof tube 4 is provided with a slide groove 12 matching the limit rod 5 settings on the bottom side of the bayonet hole 11. The slide groove 12 matches the limit rod 5 following the rotation trajectory setting of the connecting rod 2. Because of the rotation margin of the connecting rod, the slide groove 12 only needs to match the rotation margin design.
[0028] In order to facilitate the smooth insertion of the limiting rod 5 into the bayonet 11 , the bayonet 11 may be designed as a micro-horn-shaped structure with a large upper end and a small lower end.
[0029] A connecting tube 8 matching the connecting rod 2 is provided at the top of the rain-shielding umbrella 7 , and the rain-shielding umbrella 7 is fixedly connected to the connecting rod 2 via the connecting tube 8 , thereby enhancing the connection strength between the rain-shielding umbrella 7 and the connecting rod 2 .
[0030] A plurality of evenly distributed reinforcing ribs A9 are arranged around the outer side of the connecting tube 8 and the upper end of the rainproof umbrella 7 .
[0031] A plurality of evenly distributed reinforcing ribs B10 are arranged around the outer side of the waterproof tube 4 and the top upper end of the mechanism box body 1 .
[0032] The reinforcing ribs A9 and B10 are cylindrical structures, trapezoidal plane structures or triangular plane structures, respectively used to further strengthen the connection strength at their corresponding positions and extend the service life. The cylindrical structure should not be too heavy to avoid increasing the burden, and a hollow structure can be used.
[0033] After the connecting rod 2 is passed through the top of the mechanism box body 1 , a sealing material 3 is provided between the connecting rod 2 and the top of the mechanism box body 1 . This is the prior art processing method of the connecting rod 2 and the mechanism box body 1 .
[0034] Different from the existing technical processing method, the connecting rod 2 can also be passed through the top of the mechanism box body 1 through the sealed bearing 3, wherein the sealed bearing 3 is equivalent to the sealing material 3, and can also play a certain relative sealing role, but at the same time, the sealed bearing 3 is also beneficial to the smooth rotation of the connecting rod 2, prevents jamming, and makes the various working conditions of the connecting rod 2 smoother.
[0035] During the specific implementation, all materials are made of stainless steel, which has a strong ability to prevent rainwater corrosion, and can further improve the rainwater blocking function of the waterproof tube 4, the guide tube 6, the rainproof umbrella 7, etc., and prolong the use time.
[0036] When the present invention is actually used, the waterproof tube 4 is first fixedly connected to the connecting rod 2 on the top of the mechanism box body 1 by welding to surround the connecting rod 2. The connecting tube 8, the rain umbrella 7 and the guide tube 6 can be pre-made into an integrated structure, and then the connecting tube 8 of the integrated structure is fixedly connected to the connecting rod 2 by welding. The connecting rod 2 with the welded integrated structure is inserted into the mechanism box body 1. During the insertion process, pay attention to docking the limit rod 5 and the bayonet 11 so that the limit rod 5 is just stuck into the bottom of the bayonet 11 (that is, the intersection of the bayonet 11 and the slide groove 12) and then it can be put into use.
[0037] During the use of the present invention, the welding connection between the connecting rod 2 and the connecting tube 8 is blocked from the top, the welding connection between the waterproof tube 4 and the top of the mechanism box body 1 is blocked from the bottom, and the butt connection between the umbrella 7, the guide tube 6 and the waterproof tube is blocked from the middle, thereby isolating rainwater and preventing rainwater from corroding the connection between the connecting rod 2 and the mechanism box body 1, thereby preventing rainwater from leaking from the cross connection between the two, thereby effectively reducing the defect rate of the traditional operating mechanism box of the outdoor substation. After a period of practical use, it was verified that the traditional operating mechanism box of the outdoor substation using the above structure can effectively reduce the defect rate, and its defect rate can be reduced from the original 22.35% to 11.06%, effectively ensuring the safe and stable operation of the electrical equipment of the substation.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the specific implementation modes of the present invention can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
