Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically to an online monitoring device for transformer oil chromatography. Background Technology

[0002] Transformer oil chromatography equipment uses chromatography to determine the composition of dissolved gases in transformer oil. It is an effective means for power generation and supply companies to determine whether there are latent overheating, discharge, or other faults in operating oil-filled electrical equipment, thus ensuring the safe and efficient operation of the power grid. It is also a necessary means for manufacturers of oil-filled electrical equipment to conduct factory inspections of their equipment.

[0003] For example, the publication number is April 1, 2025, and the title is "A Fixed Structure for Installing Online Monitoring Equipment for Transformer Oil Chromatography". It includes a fixed structure and a monitoring device installed on the top of the fixed structure. The output end of the motor is equipped with a rotating shaft, and the outer surface of the rotating shaft is equipped with gears. It belongs to the field of transformer oil chromatography. In order to solve the problem that the installation of fixing with screws requires the use of other auxiliary tools, which wastes a lot of time, the monitoring device is placed inside the fixed structure. The support feet of the monitoring device are placed at the bottom of the base through the inside of the slot. When the motor is started, the triangular teeth mesh with the gears, so that the gears drive two sets of drive bars to move to both sides of the base through the triangular teeth, so that the moving plate moves to one side of the slot. The set limit strip restricts the movement of the drive bars. The locking strip is sleeved on the support feet of the monitoring device. The set rubber layer protects the support feet and fixes the position of the monitoring device to prevent the monitoring device from tipping over.

[0004] In the existing technology, monitoring cabinets are usually set in a square concrete foundation with a groove for installing the monitoring cabinet. However, since the monitoring cabinet is installed from top to bottom in the installation groove of the concrete foundation, it usually requires the use of hoisting equipment to lift the monitoring cabinet and put it into the installation groove before installation can be carried out, which makes the installation inconvenient.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-5 The present invention provides an online transformer oil chromatography monitoring device, comprising: a monitoring cabinet 1, the bottom of which is fixedly connected with a plurality of casters 11; specifically, there are four casters 11, each caster 11 being fixedly connected to the four corners of the bottom of the monitoring cabinet 1; by setting the casters 11, it is convenient for staff to push the monitoring cabinet 1 to move and push it into the fixed foundation for installation.

[0026] The fixed foundation includes a first plate 2, which is fixedly connected to the ground by bolts; two second plates 3 are provided on the first plate 2; specifically, the two second plates 3 are arranged parallel to each other, and both second plates 3 are perpendicular to the first plate 2. The two second plates 3 and the first plate 2 form a U-shaped fixed foundation, and the monitoring cabinet 1 is pushed into the interior of the fixed foundation through the opening of the U-shape.

[0027] Two locking mechanisms 4 are respectively disposed on the two second plates 3; specifically, the locking mechanisms 4 are used to lock the monitoring cabinet 1 to the second plates 3. More specifically, the locking mechanism 4 includes a fixed plate 41 fixedly connected to the monitoring cabinet 1, a first sliding groove 31 provided on the second plate 3, the fixed plate 41 slidingly engaging with the first sliding groove 31, and a locking rod 42 slidably connected to the second plate 3; wherein, the end of the locking rod 42 is set with an inclined surface; the inclined surface of the locking rod 42 faces the direction of the U-shaped opening, and the inclined surface of the locking rod 42 abuts against the fixed plate 41; the locking rod 42 is inserted into the fixed plate 41; the fixed plate 41 is provided with a slot for the locking rod 42 to be inserted into; an elastic element 43 is provided between the locking rod 42 and the second plate 3; the elastic element 43 is a tension spring.

[0028] Understandably, the longitudinal movement of the monitoring cabinet 1 can be restricted by the sliding cooperation between the fixed plate 41 and the first slide groove 31, and the lateral movement of the monitoring cabinet 1 can be restricted by the locking effect of the locking mechanism 4.

[0029] Preferably, it also includes an adjustment mechanism 5; by setting the adjustment mechanism 5, the position of the second plate 3 on the first plate 2 can be adjusted, thereby facilitating the installation of monitoring cabinets 1 of various sizes.

[0030] Specifically, the adjusting mechanism 5 includes a slider 51 fixedly connected to the second plate 3, a second slide groove 21 for sliding the slider 51 on the first plate 2, and a rotating rod 52 rotatably connected to the slider 51. Specifically, the rotating rod 52 passes through and extends to the outside of the first plate 2, and the rotating rod 52 is L-shaped. The L-shape facilitates the rotation of the rotating rod 52. A torsion spring is provided between the rotating rod 52 and the slider 51. Specifically, a through groove 22 for sliding the rotating rod 52 is provided on the first plate 2. A pawl 53 is fixedly connected to the rotating rod 52, and a ratchet 54 is fixedly connected in the second slide groove 21. The pawl 53 and the ratchet 54 engage with each other.

[0031] Working principle: When in use, the distance between the two second plates 3 needs to be adjusted first to fit the size of the monitoring cabinet 1; the slider 51 slides in the second slide groove 21, so that the pawl 53 and the ratchet 54 repeatedly engage, so that the rotating rod 52 overcomes the elastic force of the torsion spring and rotates repeatedly, thereby locking the position of the second plate 3 through the unidirectional transmission characteristics of the pawl 53 and the ratchet 54.

[0032] Subsequently, the monitoring cabinet 1 is pushed to move, so that the monitoring cabinet 1 is pushed into the fixed base from the space between the two second plates 3. During the movement of the monitoring cabinet 1, the fixed plate 41 slides in the first slide groove 31. As the fixed plate 41 continues to slide, the corner of the fixed plate 41 will abut against the inclined surface of the locking rod 42, driving the locking rod 42 to slide on the second plate 3, thereby causing the elastic element 43 to deform and extend. As the fixed plate 41 slides, until the slot on the fixed plate 41 moves to a position flush with the locking rod 42, the elastic element 43 restores its elasticity, causing the locking rod 42 to be inserted into the fixed plate 41, locking the monitoring cabinet 1.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
