Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of capacitor compensation cabinet, especially relates to a power engineering capacitor compensation cabinet. BACKGROUND

[0002] Most of the load types in the power system belong to inductive load, which makes the power factor of the power grid low. Low power factor reduces equipment utilization, increases power supply investment, damages voltage quality, reduces equipment service life, and greatly increases line loss. Therefore, by connecting a capacitor compensation cabinet in the power system, the inductive load can be balanced, the power factor can be improved, and the utilization rate of the equipment can be improved.

[0003] When assembling the capacitor compensation cabinet, the components need to be installed one by one inside the cabinet. The electronic components inside the capacitor compensation cabinet need to be regularly maintained and maintained. The Chinese utility model patent with authorization announcement number "CN217956431U" discloses a capacitor compensation cabinet, which comprises a cabinet body and a cabinet door. The cabinet door and the cabinet body are rotatably connected and can be opened or closed by rotating. The upper part of the front panel of the cabinet body is provided with a touch screen. The touch screen is located on the upper side of the cabinet door and the touch screen is located at the middle position in the width direction of the cabinet body. The two sides of the width direction of the touch screen are respectively provided with a first air outlet and a second air outlet.

[0004] The above technical scheme sets the first air outlet and the second air outlet on the front panel, avoiding the rainwater from entering or the dust from accumulating caused by setting the air outlet on the top wall. When the cooling fan is working, the air flow in the cabinet body can be accelerated, which is beneficial to the heat dissipation of the capacitor compensation cabinet. However, the above technical scheme still has certain defects. When assembling the capacitor compensation cabinet, the components need to be installed one by one inside the cabinet. The electronic components inside the capacitor compensation cabinet need to be regularly maintained and maintained. When the staff is maintaining, the body needs to be inserted into the inside of the capacitor compensation cabinet for checking. The space inside the capacitor compensation cabinet is limited and is restricted by the cabinet walls on both sides of the capacitor compensation cabinet. When the staff is checking by inserting, the field of vision may be limited, which leads to the fact that all components cannot be observed comprehensively and clearly, and the capacitor cannot be maintained conveniently, which affects the maintenance efficiency. Therefore, the utility model provides a new solution. UTILITY MODEL CONTENTS

[0031] Please refer to Figures 1-5 The utility model provides a technical scheme: a kind of electric power engineering capacitor compensation cabinet, including capacitor compensation cabinet 1 and mounting plate 6, mounting plate adjusting assembly, mounting plate adjusting assembly is set in the inside of capacitor compensation cabinet 1, mounting plate adjusting assembly includes fixed frame 9, fixed frame 9 is fixedly connected in the inside of capacitor compensation cabinet 1, the inner wall of fixed frame 9 is fixedly connected with first rack 10, the inner wall of fixed frame 9 is slidably connected with second rack 11, screw rod 15 is rotatably connected in the inside of capacitor compensation cabinet 1, the surface of screw rod 15 is threadedly connected with movable rack 12, the surface of fixed frame 9 is fixedly connected with limit plate 13, movable rack 12 is slidably connected with fixed frame 9 and limit plate 13, the inside of movable rack 12 is rotatably connected with gear 14, first rack 10 and second rack 11 are all engaged with gear 14, second rack 11 is fixedly connected with mounting plate 6.

[0032] The number of mounting plate adjusting assembly is two, and is symmetrically arranged on the two sides of the inside of capacitor compensation cabinet 1.

[0033] The surface of two screw rods 15 is fixedly connected with sprocket 17, the surface of two sprockets 17 is drivingly connected with chain 18, the surface of right screw rod 15 is fixedly connected with handle 16.

[0034] The front end of capacitor compensation cabinet 1 is hingedly connected with cabinet door 2, the top of capacitor compensation cabinet 1 is fixedly connected with protection plate 24, the inside top end of capacitor compensation cabinet 1 is fixedly installed with cooling fan 4, the top of capacitor compensation cabinet 1 is fixedly connected with dust screen 3, and the left and right sides of capacitor compensation cabinet 1 are respectively provided with a plurality of cooling grooves 5.

[0035] The inner wall of the capacitor compensation cabinet 1 is fixedly connected with a fixed support 7, and the inside of the capacitor compensation cabinet 1 is fixedly connected with a fixed rod 8. The fixed support 7 is fixedly connected with the fixed rod 8. Both the fixed support 7 and the fixed rod 8 have four in number and are symmetrically arranged in the inside of the capacitor compensation cabinet 1. The mounting plate 6 is slidably connected with the four fixed rods 8.

[0036] A plurality of through holes are formed in the surface of the mounting plate 6. A plurality of capacitors 19 are fixedly installed on the mounting plate 6. Three electric appliance mounting racks 20 are fixedly connected with the surface of the mounting plate 6. A plurality of switches 21, circuit breakers 22 and AC contactors 23 are fixedly installed on the surface of the three electric appliance mounting racks 20, respectively.

[0037] When the capacitor compensation cabinet is used, the top of the capacitor compensation cabinet 1 is protected by the protective plate 24. The mineral outside the capacitor compensation cabinet 1 is discharged from the heat dissipation fan 4 to the inside of the capacitor compensation cabinet 1 by starting the heat dissipation fan 4, and circulates in the inside of the capacitor compensation cabinet 1. The air is discharged from the heat dissipation grooves 5 on both sides of the capacitor compensation cabinet 1. It is convenient to discharge the heat generated in the inside of the capacitor compensation cabinet 1 with the air, and to improve the heat dissipation effect of the device.

[0038] Since the capacitors 19, switches 21, circuit breakers 22 and AC contactors 23 in the inside of the capacitor compensation cabinet 1 may fail during use, they need to be repaired or replaced when failure occurs. Rotating the handle 16 drives the threaded rod 15 to rotate, the threaded rod 15 drives the sprocket 17 and the chain 18 to rotate, and then drives the other threaded rod 15 to rotate. The threaded rod 15 drives the movable frame 12 to slide in the inside of the fixed frame 9. The movable frame 12 drives the gear 14 to rotate on the surface of the first rack 10. Since the first rack 10 is fixed in the inside of the fixed frame 9, the gear 14 rotates and moves on the surface of the limiting plate 13. At the same time, the gear 14 drives the second rack 11 to slide in the inside of the fixed frame 9. The fixed frame 9 drives the mounting plate 6 to slide in the inside of the capacitor compensation cabinet 1. It is convenient to adjust the position of the mounting plate 6, to expose the capacitors 19, switches 21, circuit breakers 22 and AC contactors 23 on the surface of the mounting plate 6, to repair the capacitors 19, to replace the capacitors 19, and to improve the repair efficiency of the capacitor compensation cabinet.

By providing stable support, the capacitor is more convenient to install or replace, improves work efficiency, reduces operation difficulty and risk, facilitates the inspection and maintenance operation of the workers, improves the repair efficiency and accuracy.

[0040] Further, by moving the mounting plate 6, the surface of the capacitor 19, switch 21, circuit breaker 22 and AC contactor 23 are exposed, avoiding the restriction of the inner walls of the capacitor compensation cabinet 1 during maintenance and replacement, making the installation, replacement and maintenance of the capacitor more convenient, reducing the operation difficulty, improving the work efficiency, making it easier to access the capacitor during maintenance and detection, reducing the safety hazards during operation, and also helping to quickly disconnect the capacitor from the power grid in emergency situations.

[0041] By setting the heat dissipation fan 4 and the heat dissipation groove 5, the electrical appliances in the capacitor compensation cabinet 1 will generate heat during operation. The heat dissipation fan can help the electrical appliances dissipate heat and ensure the normal operation of the electrical appliances. The heat dissipation fan 4 can quickly discharge the heat accumulated inside the capacitor compensation cabinet 1 through forced convection, keep the equipment operating within the ideal temperature range, improve the heat dissipation effect of the capacitor compensation cabinet, prevent performance degradation or safety accidents caused by overheating, and improve the safety of the capacitor compensation cabinet.

[0042] Working principle: In use, the top of the capacitor compensation cabinet 1 is protected by the protective plate 24, the heat dissipation fan 4 is started to discharge the minerals outside the capacitor compensation cabinet 1 from the heat dissipation fan 4 to the inside of the capacitor compensation cabinet 1, and circulate in the inside of the capacitor compensation cabinet 1, and the air is discharged from the heat dissipation grooves 5 on both sides of the capacitor compensation cabinet 1, which facilitates the discharge of heat generated inside the capacitor compensation cabinet 1 with the air, improving the heat dissipation effect of the device.

[0043] Since the capacitor 19, switch 21, circuit breaker 22 and AC contactor 23 inside the capacitor compensation cabinet 1 may fail during use, maintenance or replacement is required when a fault occurs. Rotate the handle 16 to drive the threaded rod 15 to rotate, the threaded rod 15 drives the sprocket 17 and chain 18 to rotate, and then drives the other threaded rod 15 to rotate, the threaded rod 15 drives the movable frame 12 to slide inside the fixed frame 9, the movable frame 12 drives the gear 14 to rotate on the surface of the first rack 10, since the first rack 10 is fixed inside the fixed frame 9, the gear 14 rotates and moves on the surface of the limiting plate 13, and at the same time the gear 14 drives the second rack 11 to slide inside the fixed frame 9, the fixed frame 9 drives the mounting plate 6 to slide inside the capacitor compensation cabinet 1, facilitating the adjustment of the position of the mounting plate 6, exposing the surface of the capacitor 19, switch 21, circuit breaker 22 and AC contactor 23 on the mounting plate 6, facilitating the maintenance and replacement of the capacitor 19, and improving the maintenance efficiency of the capacitor compensation cabinet.

[0044] During the movement of the mounting plate 6 in the interior of the capacitor compensation cabinet 1, the mounting plate 6 slides on the surface of the corresponding fixed rod 8, and the fixed rod 8 can support the mounting plate 6, thereby improving the stability of the mounting plate 6 during movement, making the capacitor more convenient to install or replace, improving work efficiency, reducing operation difficulty and risk, facilitating the inspection and maintenance operation of the staff, improving maintenance efficiency and accuracy.

[0045] The utility model has been described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the art without departing from the purpose of the utility model.
