Description

Technical Field

[0001] This utility model relates to the field of power equipment monitoring technology, specifically to a substation monitoring device. Background Technology

[0002] Substations are the hubs of the power grid system, responsible for voltage transformation, power distribution, and control. The stable operation of their internal electrical equipment directly affects the safety and reliability of the entire power grid. With the deepening of smart grid construction, higher demands are placed on the intelligent operation and maintenance of substations. Traditional manual periodic inspections and single fault alarm modes are no longer sufficient to meet the needs of modern power grids for real-time equipment status perception, early fault warning, and precise fault location.

[0003] Transmission switches are common electrical components in substations, used to control the starting of equipment or the connection of circuits. When a short circuit occurs in the line or equipment is damaged, the transmission switch will trip to protect the line or equipment.

[0004] Traditional substation switches often lack effective real-time monitoring and automatic alarm mechanisms after tripping, making it difficult for on-site personnel to detect the tripping situation and locate the fault in a timely manner. This information lag prevents the rapid organization of repairs and maintenance for short-circuited lines or faulty equipment, leading to a series of chain reactions such as prolonged power outages, expanded fault impact areas, and accelerated equipment damage, seriously affecting power supply reliability and system operational safety. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a substation monitoring device that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a substation monitoring device, comprising: A transformer switch, wherein a mounting plate is provided on the outside of the transformer switch; The fixing mechanism includes a screw seat fixedly connected to the outside of the mounting plate, wherein a threaded rod is rotatably connected to the inner wall of the screw seat via a bearing, and two mirror-distributed L-shaped strips are threadedly connected to the outer side of the threaded rod; The monitoring mechanism includes a fixed block fixedly connected to the outside of the mounting plate. A second contact element is provided on the top of the fixed block. A base block is provided above the fixed block. A first contact element is provided at the bottom of the base block. A transmission rod is fixedly connected to the top of the base block. A buzzer is installed on the outside of the mounting plate. Two alarm lights are installed on the outside of the mounting plate.

[0007] Preferably, the threaded rod has reverse threads at both ends, and handles are fixedly connected to both ends of the threaded rod.

[0008] Preferably, rubber pads are fixedly connected to the opposite surfaces of the two L-shaped strips, and the rubber pads are arranged in an L-shape.

[0009] Preferably, two sets of symmetrically distributed limiting rods are fixedly connected to the outside of the screw seat, and two symmetrically distributed limiting grooves are opened on the outside of the L-shaped strip, with the limiting rods slidably connected to the inner wall of the corresponding limiting groove.

[0010] Preferably, a limiting sleeve is fixedly connected to the outer side of the mounting plate, the top end of the transmission rod passes through the limiting sleeve and is slidably connected to the inner wall of the limiting sleeve, and an arc-shaped block is fixedly connected to the end of the transmission rod away from the bottom block.

[0011] Preferably, a tension spring is fixedly connected to the top of the base block, and the end of the tension spring away from the base block is fixedly connected to the bottom of the limiting sleeve.

[0012] Preferably, a storage battery is fixedly connected to the outside of the mounting plate, and the storage battery is electrically connected to contact one, contact two, a buzzer and an alarm light.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, by setting up a monitoring mechanism, can monitor in real time whether the substation switch has tripped during use. When the substation switch trips, the buzzer and alarm light can work simultaneously to remind the staff, making it convenient for the staff to discover and organize personnel for maintenance in a timely manner, effectively avoiding the occurrence of subsequent chain reactions, thereby ensuring the reliability of power supply and the safety of system operation.

[0014] 2. By setting a fixing mechanism, this utility model can quickly fix the mounting plate together with the monitoring mechanism to the outside of the substation switch, so that the monitoring mechanism can continuously and stably monitor whether the substation switch has tripped. Moreover, the distance between the two L-shaped bars is adjustable, so that the substation monitoring device can be adapted to substation switches of different sizes and has good applicability.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments. Example

[0020] Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a substation monitoring device, comprising: The transformer switch 2 has a mounting plate 1 on its outer side, which provides the mounting base for the entire monitoring device. The monitoring mechanism 4 includes a fixing block 411 fixedly connected to the outside of the mounting plate 1. A second contact 410 is provided on the top of the fixing block 411. A base block 48 is provided above the fixing block 411. A first contact 49 is provided at the bottom of the base block 48. A transmission rod 45 is fixedly connected to the top of the base block 48 for transmitting actions. A buzzer 44 is installed on the outside of the mounting plate 1. Two symmetrically distributed alarm lights 43 are installed on the outside of the mounting plate 1. The buzzer 44 provides an audible alarm, and the alarm lights 43 provide a visual alarm. The dual warning ensures effective information transmission.

[0021] Specifically, a limiting sleeve 46 is fixedly connected to the outer side of the mounting plate 1. The top end of the transmission rod 45 passes through the limiting sleeve 46 and is slidably connected to the inner wall of the limiting sleeve 46 to ensure that the transmission rod 45 can only move stably in the vertical direction and prevent swaying. When the substation switch 2 trips, the transmission rod 45 can move stably in the vertical direction. An arc-shaped block 42 is fixedly connected to the end of the transmission rod 45 away from the bottom block 48. The shape of the arc-shaped block 42 is designed to make good contact with the switch of the substation switch 2 to ensure that the trip button can be reliably pressed against the arc-shaped block 42 when it is activated.

[0022] Specifically, a tension spring 47 is fixedly connected to the top of the base block 48. The end of the tension spring 47 away from the base block 48 is fixedly connected to the bottom of the limiting sleeve 46. In the non-alarm state, the tension of the tension spring 47 keeps the base block 48 and the first contact 49 in the upper limit position and separates them from the second contact 410.

[0023] Specifically, a battery 41 is fixedly connected to the outside of the mounting plate 1. The battery 41 forms an electrical connection circuit with contact 49, contact 410, buzzer 44, and alarm light 43 through wiring. When contact 49 contacts contact 410, the circuit is completed, triggering an audible and visual alarm.

[0024] In this embodiment, when the transformer switch 2 is operating normally, its switch is in its original position, and the first contact 49 and the second contact 410 of the monitoring mechanism 4 are separated under the action of the tension spring 47, thus disconnecting the alarm circuit. When the transformer switch 2 trips, its switch will rotate or move downwards. During this process, the switch presses the arc-shaped block 42, forcing the transmission rod 45 to move downwards against the tension of the tension spring 47, thereby pushing the bottom block 48 and the first contact 49 downwards until they contact the second contact 410 on the fixed block 411. At this moment, the circuit consisting of the battery 41, the first contact 49, the second contact 410, the buzzer 44, and the alarm light 43 is connected, the buzzer 44 immediately sounds, and the two alarm lights 43 flash synchronously, generating a significant audible and visual alarm signal. This signal can promptly alert nearby staff to a tripping event, prompting them to quickly locate and organize repairs. This effectively prevents cascading failures and power outages that could result from failure to detect the tripping in time, significantly improving the reliability and operational safety of the power supply system. After the fault is cleared, when staff push the switch of transformer 2 back to its original position (upward rotation), the pressure on the arc-shaped block 42 disappears. The bottom block 48 and contact 49 move upward under the restoring force of the tension spring 47, separating from contact 410. The circuit is broken, the audible and visual alarm stops, and the device automatically returns to monitoring standby mode. Example

[0025] Reference Figure 1-4This is the second embodiment of the present invention, which differs from the first embodiment in that: The fixing mechanism 3 includes a screw seat 32 fixedly connected to the outside of the mounting plate 1. The inner wall of the screw seat 32 is rotatably connected to a threaded rod 33 through a bearing, ensuring that the threaded rod 33 can rotate smoothly and be axially fixed. The outside of the threaded rod 33 is threadedly connected to two mirror-distributed L-shaped strips 34, which are used to quickly and securely install the mounting plate 1 and the monitoring mechanism 4 integrated thereon on the outside of the substation switch 2 of different sizes.

[0026] Specifically, the threaded rod 33 has reverse threads at both ends, and handles are fixedly connected to both ends of the threaded rod 33. When the threaded rod 33 rotates, due to the action of the reverse threads, the two L-shaped bars 34 will move synchronously towards or away from each other. The operator can easily drive the threaded rod 33 to rotate by rotating either handle, thereby adjusting the distance between the two L-shaped bars 34.

[0027] Specifically, rubber pads 35 are fixedly connected to the opposite surfaces of the two L-shaped strips 34. The rubber pads 35 are L-shaped and are used to protect the surface of the transformer switch 2 from damage when clamping it, and to increase the clamping friction to prevent slippage.

[0028] Specifically, two sets of symmetrically distributed limiting rods 31 are fixedly connected to the outside of the screw seat 32, and two symmetrically distributed limiting grooves 36 are opened on the outside of the L-shaped strip 34. The limiting rods 31 are slidably connected to the inner wall of the corresponding limiting grooves 36. Under the action of the limiting rods 31 and the limiting grooves 36, the movement path of the L-shaped strip 34 is guided and constrained, so that it can only move in a straight line.

[0029] The remaining structure is the same as that in Example 1.

[0030] In this embodiment, when the monitoring device needs to be installed, the mounting plate 1 is placed tightly against the outside of the substation switch 2. Then, the operator rotates the handle to rotate the threaded rod 33. Driven by the reverse thread and guided by the limiting rod 31 and the limiting groove 36, the two L-shaped strips 34 with rubber pads 35 move synchronously towards the center until they firmly clamp the substation switch 2 from both sides. After installation, the monitoring mechanism 4 can continuously and reliably monitor the tripping of the substation switch 2 based on the stability provided by the fixing mechanism 3. For disassembly, simply rotate the handle in the reverse direction to release the clamp, which is convenient and quick.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
