Description

Technical Field

[0001] The present invention relates to the technical field of monitoring equipment, and more specifically, it relates to a power facility monitoring equipment that is convenient for wiring. Background Art

[0002] A voltage transformer is an electrical device used to convert high voltage into low voltage. In a power system, voltage transformers often work in cooperation with protection relays to monitor power facilities. When an abnormality occurs in the system (such as overvoltage, undervoltage, etc.), the voltage transformer provides an accurate voltage signal, enabling the protection device to respond in a timely manner and protecting power equipment from damage.

[0003] In actual applications of existing voltage transformers, according to different usage requirements, some devices are installed inside cabinets. However, during use, the secondary side of the voltage transformer is usually connected to measuring equipment, relay protection devices, or other power equipment. If there is a fault in the wiring of these connected devices, or a short circuit occurs in their internal components, it may cause a short circuit on the secondary side of the voltage transformer. In this case, a large current will be generated on the secondary side of the voltage transformer in a short period of time, generating a large amount of heat. Seriously, this will not only affect the safety of other devices inside the cabinet, but may also cause a fire, posing a serious safety hazard. Summary of the Invention

[0007] An open box is installed at the bottom of the voltage transformer, a rolling mechanism is arranged at the bottom of the open box, and a guide rod that cooperates with the rolling mechanism is installed inside the cabinet body;

[0008] A traction mechanism is arranged on the outer periphery of the voltage transformer, and the traction mechanism is cooperatively connected to both the pulling wire and the rolling mechanism. When the voltage transformer overheats or catches fire, the traction mechanism is damaged to release the pulling force on the pulling wire, causing the wiring mechanism to separate from the conductive plate.

A storage groove adapted to the covering frame is formed in the sleeve housing wall, and the covering frame is connected with an extraction member.

[0010] As a further optimized solution of the present invention, the extraction member includes a sleeve, a piston, a right-angle pull rod and an extraction pipe. The sleeve is installed on the sleeve housing and is communicated with the top of the sleeve housing through the extraction pipe. The piston is slidably arranged inside the sleeve and is slidably connected with the covering frame through the right-angle pull rod. A sliding groove adapted to the right-angle pull rod is formed in the side part of the covering frame.

[0011] As a further optimized solution of the present invention, the connection mechanism includes a conductive frame, a T-shaped insertion rod and an elastic member. The conductive frame is installed at the connection end of the voltage transformer. The insertion end of the T-shaped insertion rod slidably passes through the conductive frame and extends into the inside of the conductive plate. The T-shaped end of the T-shaped insertion rod is connected with the conductive frame through the elastic member. The two T-shaped insertion rods are connected through a pull wire.

[0012] As a further optimized solution of the present invention, the rolling mechanism includes a bottom plate and a round block. The bottom plate is installed at the bottom of the open box. The round block is rotatably sleeved at the bottom of the bottom plate. The top of the guide rod is inclined and is provided with a guide groove adapted to the round block. The bottom plate is connected with the guide rod through a positioning member.

[0013] As a further optimized solution of the present invention, the positioning member includes a mounting block, a T-shaped rotating shaft, a torsion spring, a rotating block and a limiting block. The limiting block is installed on the guide rod. The mounting block is installed at the bottom of the bottom plate. The T-shaped rotating shaft is rotatably arranged on the mounting block. One end of the T-shaped rotating shaft is fixedly connected with the rotating block, and the other end is connected with the mounting block through the torsion spring.

[0014] As a further optimized solution of the present invention, the traction mechanism includes a glass tube, a connecting wire, a guiding ball, a connecting ball, a splitting wire one and a splitting wire two. The glass tube is installed on the voltage transformer, and the inside of the glass tube is filled with thermosensitive glass beads. The guiding ball is installed on the voltage transformer. The connecting wire slidably passes through the guiding ball. The connecting ball is slidably sleeved on the connecting wire and is fixedly connected with the covering frame. The glass tube is connected with the pull wire through the splitting wire two. One end of the splitting wire one is connected with the connecting wire, and the other end slidably passes through the open box and the bottom plate and is connected with the T-shaped rotating shaft.

[0015] As a further optimized solution of the present invention, the connecting wire is arranged in a circuitous manner, is connected end to end, and is in contact with the splitting wire two.

[0016] As a further optimization solution of the present invention, an outlet for the voltage transformer and the guide rod to extend out is opened on one side of the cabinet, and a flap is rotatably connected to the outlet through a hinge.

[0017] As a further optimization scheme of the present invention, a rotating rod is rotatably connected to the top of the shell, the rotating rod is fixedly connected to a net bucket, a turntable is fixedly mounted on the rotating rod, the turntable is fixedly connected to a paddle plate, a pull rope is wrapped around the turntable, and the movable end of the pull rope is fixedly connected to the cover frame.

[0018] The beneficial effects of the present invention are:

[0019] 1. In the power facility monitoring device of the present invention, which is easy to connect, when the voltage transformer encounters an overheating or combustion fault, the traction mechanism within the device will be damaged due to the fault. This damage directly causes the connection between the wiring mechanism and the conductive plate to be quickly disconnected, thereby promptly cutting off the circuit, thereby effectively preventing the further spread of the fault.

[0020] 2. The present invention provides an easy-to-wire power facility monitoring device. When an abnormal situation occurs in the voltage transformer, a covering mechanism covers the voltage transformer, which can block the spread of heat, flames and other dangerous factors generated by the fault to a certain extent. After the covering is completed, the voltage transformer will be moved out of the cabinet with the help of the coordinated action of the rolling mechanism and the guide rod, reducing the subsequent damage that may be caused to the cabinet and other devices inside the cabinet, and further improving the safety of power facility protection.

[0021] 3. The power facility monitoring equipment that is easy to connect described in the present invention can extract the air in the covering area when the covering mechanism covers the voltage transformer, thereby reducing the oxygen content in the covering area and further reducing the spread of the fire, thereby effectively playing a flame retardant role, avoiding the deterioration of the combustion condition of the voltage transformer, and reducing the risk of fire.

[0047] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0048] As Figure 1 and Figure 2 shown, a power facility monitoring device facilitating wiring according to an embodiment of the present invention includes a cabinet body 1 and a voltage transformer 2. A covering mechanism 3 is provided above the voltage transformer 2;

[0049] Two terminal posts of the voltage transformer 2 are connected to a conductive plate 5 through a wiring mechanism 4, and the two groups of wiring mechanisms 4 are connected through a pull wire 6;

[0050] The bottom of the voltage transformer 2 is provided with an open box 7. A rolling mechanism 8 is provided at the bottom of the open box 7. A guide rod 9 cooperating with the rolling mechanism 8 is installed in the cabinet body 1;

[0051] A traction mechanism 10 is provided on the outer periphery of the voltage transformer 2. The traction mechanism 10 is cooperatively connected to both the pull wire 6 and the rolling mechanism 8. When the voltage transformer 2 overheats or catches fire, the traction mechanism 10 is damaged to release the pulling on the pull wire 6, so that the wiring mechanism 4 is separated from the conductive plate 5. The covering mechanism 3 covers the voltage transformer 2 and pumps air. At the same time, the limit of the rolling mechanism 8 is released, and the voltage transformer 2 moves out of the cabinet body 1 along the guide rod 9.

[0052] In the power facility monitoring device, each component cooperates to ensure the safe and stable operation of the device. The covering mechanism 3, the wiring mechanism 4, the pull wire 6, the open box 7, the rolling mechanism 8, the guide rod 9, and the traction mechanism 10 cooperate with each other to jointly cope with the overheating or combustion failure that the voltage transformer 2 may occur.

[0053] It should be noted that the wiring mechanism 4 connects the conductive plate 5 to the terminal of the voltage transformer 2, facilitating wiring and achieving circuit connection. The pull wire 6 between the two wiring mechanisms 4 is in a state of being tightened by the traction mechanism 10. At the same time, the traction mechanism 10 restricts the rolling mechanism 8, keeping the voltage transformer 2 stable within the cabinet 1. The covering mechanism 3 is in an unactivated state. Once the voltage transformer 2 overheats or catches fire, the traction mechanism 10 will be damaged due to the fault and release the pulling force on the pull wire 6. At this time, the wiring mechanism 4 disconnects from the conductive plate 5, cutting off the circuit and preventing the fault from further expanding. Meanwhile, the covering mechanism 3 is activated to cover and extract air from the voltage transformer 2, reducing the oxygen content inside and suppressing combustion. The limit on the rolling mechanism 8 is also released, and the voltage transformer 2 moves out of the cabinet 1 along the guide rod 9 under the action of gravity.

[0054] Referring to Figure 2 and Figure 4 the content, the covering mechanism 3 includes a sleeve 31 and a covering frame 32. The sleeve 31 is fixedly sleeved at the terminal of the voltage transformer 2. A storage groove 311 adapted to the covering frame 32 is formed in the wall of the sleeve 31. The covering frame 32 is connected with an extraction member.

[0055] It should be noted that the storage groove 311 is provided inside the sleeve 31, and its main function is to store the covering frame 32. When the equipment is operating normally and no additional protection is required for the voltage transformer 2, the covering frame 32 is stored in the storage groove 311.

[0056] Referring to Figure 4 the content, the extraction member includes a sleeve 33, a piston 34, a right-angle pull rod 35, and an extraction pipe 36. The sleeve 33 is installed on the sleeve 31 and is connected to the top of the sleeve 31 through the extraction pipe 36. The piston 34 is slidably arranged inside the sleeve 33 and is slidably connected to the covering frame 32 through the right-angle pull rod 35. A sliding groove 321 adapted to the sliding of the right-angle pull rod 35 is formed on the side of the covering frame 32.

[0057] It should be noted that as the covering frame 32 continuously moves downward inside the storage groove 311 until the inner top wall of the sliding groove 321 abuts against the right-angle pull rod 35, the right-angle pull rod 35 is driven to move, thereby moving the piston 34 to extract the air in the area between the covering frame 32 and the voltage transformer 2 into the sleeve 33, thereby reducing the oxygen content in the covering space and playing an auxiliary role in extinguishing the fire.

[0058] Referring to Figure 2 and Figure 5Content, the wiring mechanism 4 includes a conductive frame 41, a T-shaped insertion rod 42 and an elastic member 43. The conductive frame 41 is installed at the wiring terminal of the voltage transformer 2. The insertion end of the T-shaped insertion rod 42 slides through the conductive frame 41 and extends into the interior of the conductive plate 5. The T-shaped end of the T-shaped insertion rod 42 is connected to the conductive frame 41 through the elastic member 43. The two T-shaped insertion rods 42 are connected by a pull wire 6.

[0059] The conductive frame 41 is installed at the wiring terminal of the voltage transformer 2 and is used to fix the T-shaped insertion rod 42. The T-shaped insertion rod 42 is inserted into the conductive plate 5 to achieve electrical connection. When the T-shaped insertion rod 42 is inserted into the conductive plate 5, the elastic member 43 is in a compressed state at this time. When the traction mechanism 10 is damaged and the tension of the pull wire 6 disappears, the elastic member 43 returns to push the T-shaped insertion rod 42 to disengage from the conductive plate 5, realizing the disconnection of the circuit.

[0060] Refer to Figure 2 , Figure 7 and Figure 8 Content, the rolling mechanism 8 includes a bottom plate 81 and a round block 82. The bottom plate 81 is installed at the bottom of the open box 7. The round block 82 is rotatably sleeved at the bottom of the bottom plate 81. The top of the guide rod 9 is inclined and is provided with a guide groove 91 adapted to the round block 82. The bottom plate 81 is connected to the guide rod 9 through a positioning member.

[0061] It should be noted that the round block 82 is rotatably sleeved at the bottom of the bottom plate 81 and can roll in the guide groove 91 of the guide rod 9, facilitating the movement of the voltage transformer 2. The bottom plate 81 is connected to the guide rod 9 through a positioning member, restricting the movement of the voltage transformer 2 under normal circumstances.

[0062] Furthermore, the positioning member includes a mounting block 83, a T-shaped rotating shaft 84, a torsion spring 85, a rotating block 86 and a limiting block 87. The limiting block 87 is installed on the guide rod 9. The mounting block 83 is installed at the bottom of the bottom plate 81. The T-shaped rotating shaft 84 is rotatably arranged on the mounting block 83. One end of the T-shaped rotating shaft 84 is fixedly connected to the rotating block 86, and the other end is connected to the mounting block 83 through the torsion spring 85.

[0063] It should be noted that the limiting block 87 is installed on the guide rod 9 to determine the position range of the positioning member. The mounting block 83 is fixed at the bottom of the bottom plate 81, providing an installation position for the T-shaped rotating shaft 84. The T-shaped rotating shaft 84 is rotatably arranged on the mounting block 83, with one end connected to the rotating block 86 and the other end connected to the mounting block 83 through the torsion spring 85. Normally, the torsion spring 85 is in an energy storage state, and the torsion spring 85 keeps the rotating block 86 in a position where it abuts against the limiting block 87, playing a limiting role on the voltage transformer 2. When the traction mechanism 10 is damaged and the splitting wire 105 releases the limit on the T-shaped rotating shaft 84, the torsion spring 85 returns, and the rotation of the T-shaped rotating shaft 84 drives the rotating block 86 to disengage from the limit, releasing the limit on the voltage transformer 2.

[0070] Refer to Figure 4Content, the top of the shell 31 is rotatably connected to the rotating rod 12, the rotating rod 12 is fixedly connected to the net bucket 13, the rotating rod 12 is fixedly sleeved with a turntable 14, the turntable 14 is fixedly connected to the toggle piece 15, a pull rope 16 is wrapped around the turntable 14, the movable end of the pull rope 16 is fixedly connected to the cover frame 32, the net bucket 13 is a bucket-shaped filter, and a fire extinguishing dry powder is placed on it, and the net bucket 13 forms a horizontal placement portion at the bottom toward the periphery.

[0071] It should be noted that as the cover frame 32 moves downward, the pull rope 16 can be pulled, and the pull rope 16 drives the turntable 14 to rotate, so as to drive the toggle plate 15 to toggle the fire extinguishing dry powder on the net bucket 13, thereby causing the fire extinguishing dry powder to be scattered to assist in fire extinguishing. The net bucket 13 has holes, so that when the toggle plate 15 toggles the fire extinguishing dry powder, it can be scattered through the holes of the net bucket 13, thereby increasing the fire extinguishing range.

[0072] Working principle:

[0073] Normal operating state: The conductive frame 41 of the wiring mechanism 4 is fixed to the terminal of the voltage transformer 2, and the T-shaped plug 42 is inserted into the conductive plate 5 to achieve circuit connection. At this time, the elastic member 43 is in a compressed state, which reserves elastic force for subsequent circuit disconnection. The pull wire 6 between the two sets of wiring mechanisms 4 is kept in a taut state under the action of the traction mechanism 10. The glass tube 101 of the traction mechanism 10 is installed on the voltage transformer 2. Under normal circumstances, the heat-sensitive glass beads inside the glass tube 101 are not affected by high temperature, and the glass tube 101 is The second pulling wire 106 tightens the pulling wire 6. At the same time, the first pulling wire 105 connects the connecting wire 102 and the T-shaped rotating shaft 84, so that the T-shaped rotating shaft 84 remains in the limit position. At this time, the torsion spring 85 is in the energy storage state, and the rotating block 86 is blocked by the limit block 87 to limit the rolling mechanism 8, thereby stabilizing the voltage transformer 2 in the cabinet 1. The cover frame 32 of the covering mechanism 3 is stored in the storage slot 311 of the shell 31, and the flip plate 11 at the outlet on one side of the cabinet 1 is closed to prevent dust from entering the interior of the cabinet 1.

[0074] Fault triggering state: When the voltage transformer 2 is overheated or burns, the high temperature will affect the heat-sensitive glass beads in the glass tube 101, causing the glass tube 101 to be damaged. After the glass tube 101 is damaged, the pulling force of the second branch wire 106 on the pull wire 6 disappears, and the connecting wire 102 is in a loose state, releasing the restrictions on the cover frame 32 and the T-shaped shaft 84; if any wire (except the pull wire 6) is broken, the restriction can also be released.

[0075] Troubleshooting actions:

[0076] Circuit cut-off: The tension of the pull wire 6 disappears, the elastic member 43 recovers, and pushes the T-shaped rod 42 away from the conductive plate 5, thereby disconnecting the circuit and preventing the fault from further expanding.

[0077] Covering protection: The connecting ball 104 on the connecting wire 102 is fixedly connected to the cover frame 32. When the connecting wire 102 is released from the limit and moves due to the damage of the glass tube 101, the breakage of other circuits, or the breakage of the connecting wire 102, the cover frame 32 moves downward along the sleeve 31 under the action of gravity. As the cover frame 32 moves downward, until the inner top wall of the chute 321 abuts against the right-angle pull rod 35, the right-angle pull rod 35 is driven to move, so as to move the piston 34, and the air in the area between the cover frame 32 and the voltage transformer 2 is extracted, thereby reducing the oxygen content in the covered space, and thus playing an auxiliary role in extinguishing fire.

[0078] Removal of the voltage transformer 2: When the first splitting wire 105 breaks or moves, the limit on the T-shaped rotating shaft 84 is released, and the energy-storing torsion spring 85 returns, driving the T-shaped rotating shaft 84 to rotate, so that the rotating block 86 is disengaged from the abutment of the limiting block 87, and the limit of the rolling mechanism 8 is released. At this time, the round block 82 at the bottom of the voltage transformer 2 rolls in the guiding groove 91 of the guiding rod 9. Since the top of the guiding rod 9 is inclined, the voltage transformer 2 moves out of the cabinet 1 along the guiding rod 9 under the action of gravity. During the movement, the voltage transformer 2 pushes open the turning plate 11 and moves out from the outlet on one side of the cabinet 1. The stop block at the end of the guiding rod 9 limits the moving range of the voltage transformer 2 to prevent it from moving excessively and disengaging from the guiding rod 9, ensuring the safe removal of the equipment from the cabinet 1.

[0079] The embodiments of the present invention have been described above, but these embodiments are not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
