Description

Technical Field

[0001] This utility model specifically relates to the field of electrical equipment technology, and more specifically to an integrated measurement, control and protection device based on fault recording. Background Technology

[0002] In the field of power system equipment, the integrated installation of measurement and control protection devices and fault recording equipment has become an industry trend. However, in existing technologies, measurement and control devices, protection devices, and fault recording equipment are mostly installed separately, with each functional module occupying its own enclosure space, resulting in low equipment integration and complex wiring. More importantly, during equipment installation, operators must enter the equipment enclosure completely to operate the equipment. However, the internal space of standard equipment enclosures often only allows for a maintenance passage of 400-600mm. When installing large functional modules, operators must work in a bent-over or squatting position. When installing multiple equipment modules, the arrangement of equipment in the depth direction inside the enclosure creates blind spots, restricting the operator's arm movement range. This makes delicate operations such as bolt tightening and cable connection difficult, and increases the risk of tools falling and damaging precision components.

[0003] In addition, existing fixed brackets mostly use welding or bolt hard connection. After the equipment installation position is fixed, the adjacent modules need to be completely disassembled for later maintenance or replacement, which is very complicated in practice. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-7In this embodiment of the present invention, an integrated measurement, control, and protection device based on fault recording includes an equipment housing 10 and an equipment fixing mechanism 30. A door 11 is provided on one side of the equipment housing 10, allowing the main body 20 to be installed inside the housing after the door 11 is opened. An installation groove 13 and a guide groove 15 are provided on the bottom plate of the equipment housing 10. A drive screw 14 for adjusting the lateral movement position of the equipment fixing mechanism 30 is provided inside the installation groove 13. The equipment fixing mechanism 30 includes a movable frame 31 and a movable plate 32. The movable frame 31 has an L-shaped structure, and an adjustable... The screw 33, the movable plate 32 and the movable frame 31 are slidably connected, and the movable plate 32 is threadedly connected to the adjusting screw 33. When installing the main body 20 of the equipment, first open the box door 11, then control the movable plate 32 to move to the outside of the box door 11 by adjusting the screw 33. Then install the main body 20 of the equipment on the movable plate 32. Finally, adjust the position of the movable frame 31 by driving the screw 14 so that the main body 20 of the equipment reaches the preset installation position. The installer can disassemble and assemble the main body 20 of the equipment without entering the equipment box 10 at the preset installation position, which improves the convenience of installing the main body 20 of the equipment.

[0023] It should be noted that the main body 20 of the equipment in this embodiment includes one or more of a measurement and control device, a protection device, and a fault recording device. The measurement and control device is used to monitor parameters such as current and voltage. The protection device is used to cut off the circuit when a fault is detected to prevent equipment damage or the expansion of the accident. The fault recording device is used to record the waveform of the change of relevant electrical quantities (such as voltage and current) over time when a fault occurs in the power system. In this embodiment, the measurement and control device, the protection device, and the fault recording device are installed together as the main body 20 inside the equipment enclosure 10 to achieve efficient utilization of the equipment enclosure and reduce the installation and maintenance costs of the equipment.

[0024] Furthermore, in the embodiments of this application, such as Figures 6-7As shown, a threaded sleeve 141 is threaded onto the drive screw 14, and a connecting frame 17 is fixedly connected to the threaded sleeve 141. An iron plate 18 and a base 19 are provided on the inner side of the connecting frame 17. The iron plate 18 is slidably connected to the base 19, and the iron plate 18 is connected to the base 19 via a return spring. An electromagnet 37 is installed at the bottom of the movable frame 31, and the movable frame 31 is slidably connected to the guide groove 15. Since the equipment body 20 has multiple types, in order to install multiple equipment bodies 20 at preset installation positions, this… In this embodiment, the equipment housing 10 is provided with multiple equipment fixing mechanisms 30 inside. When the position of the equipment fixing mechanism 30 is adjusted laterally, the electromagnet 37 of the equipment fixing mechanism 30 whose position needs to be adjusted is energized. Then, the screw sleeve 141 is controlled to move by the drive screw 14. During the movement of the screw sleeve 141, when the iron plate 18 approaches the energized electromagnet 37, the electromagnet 37 attracts the iron plate 18, causing the screw sleeve 141 to drive the equipment fixing mechanism 30 to move, thereby adjusting the position of the equipment body 20 on the equipment fixing mechanism 30.

[0025] In addition, it should be noted that a first motor 16 is fixedly installed on the bottom plate of the equipment housing 10. The first motor 16 is used to control the rotation of the drive screw 14 to realize the lateral position adjustment of the equipment fixing mechanism 30. A second motor 35 is fixedly installed on the moving frame 31. The second motor 35 is used to control the rotation of the adjusting screw 33 to realize the position adjustment of the moving plate 32.

[0026] In this embodiment, an air intake mechanism 40 is provided on the inner side of the equipment housing 10. The air intake mechanism 40 includes an air intake pipe 41 and a baffle 42. The air intake pipe 41 has several air outlets on the side facing the equipment fixing mechanism 30. An air intake plate 43 is slidably installed at the air outlets, and several inner air inlets 45 are provided on the air intake plate 43. The baffle 42 is installed on the outer side of the air intake pipe 41, and several outer air inlets 44 are provided on the baffle 42. In the initial state, the outer air inlets 44 and the inner air inlets 45 are staggered, and the air inside the air intake pipe 41 cannot flow out. When the equipment fixing mechanism 30 moves to the corresponding outer air inlet 44, the outer air inlet 44 and the inner air inlet 45 are connected, and the air inside the air intake pipe 41 flows out and blows air to cool the equipment body 20 on the equipment fixing mechanism 30. Further, in this embodiment... A top rod 46 is fixedly installed on the upper side of the air inlet plate 43, and the top rod 46 is slidably connected to the air inlet pipe 41. The lower side of the air inlet plate 43 is connected to the air inlet pipe 41 through a connecting spring 47. A moving groove is opened on the rear side of the vertical section of the movable frame 31. The air inlet pipe 41 is slidably installed in the moving groove. A protrusion 36 that cooperates with the top rod 46 is provided in the moving groove. When the equipment fixing mechanism 30 moves to the corresponding external air outlet 44, the protrusion 36 presses the top rod 46, causing the air inlet plate 43 to slide downward, thereby connecting the external air outlet 44 and the internal air outlet 45. In addition, it should be noted that a number of air blowing ports 34 are opened on the vertical section of the movable frame 31. The external air outlet 44 and the internal air outlet 45 are connected. The air inside the air inlet pipe 41 flows out and enters the air blowing port 34 to achieve heat dissipation for the main body 20 of the equipment.

[0027] In this embodiment of the application, a cooling fan 12 is installed on the outside of the equipment housing 10. The exhaust end of the cooling fan 12 is connected to one side of the air inlet pipe 41 through an air duct. The cooling fan 12 is used to provide cooling air into the air inlet pipe 41 so that the cooling air can dissipate heat from the main body of the equipment 20.
