Description

Technical Field

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

[0002] In power systems, power monitoring cabinets in substations are used to install power monitoring terminals, communication units, protection devices, data acquisition equipment, etc., undertaking the functions of real-time monitoring, control, and information transmission of substations and distribution lines. The monitoring cabinets typically require the installation of numerous high-voltage, low-voltage, and communication lines. These lines are not only numerous and of varying specifications, but also require frequent adjustments, expansions, or replacements during operation and maintenance. Therefore, the rationality and maintainability of the line layout directly affect the operational efficiency and security of the monitoring system.

[0003] Currently, power monitoring cabinets in power plants commonly use methods such as cable management straps, bolts, and clamps to fix and constrain the wiring. While these methods provide some restraint and positioning during initial installation, they have the following significant drawbacks:

[0004] Complex wiring and messy layout: The wire bundles fixed by tape or clamps are mostly point-like constraints, which cannot form a clear cable channel. As the number of lines increases and is modified, they are prone to crisscrossing, tangling and overlapping, resulting in a messy and disorderly overall wiring structure.

[0005] Line identification is difficult: Due to the lack of hierarchical, zoned or labeled management, strong and weak current lines are often mixed together. Maintenance personnel need to spend a lot of time identifying them one by one when maintaining or troubleshooting, which increases the risk of misoperation.

[0006] Inconvenient expansion and maintenance: When it is necessary to add or replace lines, the original strip must be cut or the clamps must be removed before operation, which is not only time-consuming and laborious, but may also cause adjacent lines to loosen or be damaged, reducing the reliability of system operation.

[0007] Lack of mechanical protection and limiting: Traditional fixing methods cannot effectively control the bending radius and spacing of cables, which can easily lead to cable breakage and insulation wear during long-term operation, affecting the safe operation of monitoring equipment.

[0008] Therefore, the existing internal wiring management methods of power plant monitoring cabinets are inadequate in terms of structural layout, identification efficiency, expansion convenience, and operational safety. There is an urgent need for an improved cable management system with standardized wiring channels, zoned identification management, and rapid maintenance and expansion capabilities to meet the high reliability and high efficiency operation and maintenance requirements of modern power monitoring systems. Utility Model Content

[0009] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0010] Therefore, the technical solution adopted by this utility model is as follows: a power monitoring device for a power supply station, including a monitoring cabinet, cable trays, cable clamping components, and a monitor. The monitoring cabinet is used to install, support, and protect the internal power monitoring lines and equipment. Several cable trays are arranged parallel to the line direction inside the cabinet to provide a base for cable support. The surface of the cable trays is provided with slide rails and positioning corrugations to provide guidance and positioning functions for the installation of the cable clamping components. The cable clamping components include two sets of opposing interlocking clamping slots, positioning blocks, and spring-loaded structures to achieve reliable clamping and vibration-damping fixation of the power lines. The monitor is fixed inside the monitoring cabinet and is used to monitor power operating parameters in real time.

[0011] In a preferred embodiment, multiple cable trays are arranged parallel to each other along the inner wall of the monitoring cabinet, providing a segmented mounting base for multiple power lines. Specifically, the cable tray surface is equipped with slide rails, and the slide rail surface has positioning corrugations. These positioning corrugations can elastically abut against the positioning blocks of the cable clamping assembly, ensuring the precise positioning and limiting of the cable clamping assembly in the installation position, thereby preventing displacement during operation. This arrangement enables neat wiring and rapid positioning, improving wiring efficiency.

[0012] In a preferred embodiment, the cable fastening assembly is slidably mounted onto the cable tray along a slide rail via the bottom of the positioning block, and adjacent cable fastening assemblies can be installed in parallel through the engagement of spring-loaded lugs and slots. Specifically, the cable fastening assembly includes two sets of opposing fastening slots. Each fastening slot has a wire groove on its surface, and slots and spring-loaded lugs are respectively provided on both sides of the wire groove. The spring-loaded lug has a mushroom-shaped cross-section and a deformation gap in the middle. After being inserted into the slot, it can automatically limit and prevent detachment by relying on its cross-sectional shape and elastic deformation. During cable laying, the operator only needs to place the cable into the wire groove and close and lock the two sets of fastening slots to complete the fixation, which is simple and stable.

[0013] In a preferred embodiment, the snap-fit ​​assembly has a snap fastener on its spring-loaded lug surface. The snap fastener engages with the deformation gap to control the deformation of the spring-loaded lug, thereby enabling unlocking and disengagement. When adjacent snap-fit ​​assemblies are installed in parallel, the snap fasteners hook together and the snap rings overlap and are arranged coaxially. Secondary locking can be achieved by inserting the snap rings into the locking pin, thereby further improving vibration resistance and connection reliability. This is particularly suitable for operating conditions in power station environments where vibration and impact are present.

[0014] In a preferred embodiment, the entire wire fastening assembly is made of flame-retardant engineering plastic, which has the safety characteristics of high temperature resistance and flame retardancy. It can effectively prevent the risk of fire caused by internal heating of the power station or short circuit of the line, and significantly improve the operational safety and reliability.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, by setting a cable tray along the cable routing direction on the inner wall surface of the monitoring cabinet, and installing a sliding cable fastening component on the cable tray surface in conjunction with a slide rail and positioning corrugation, the guiding positioning and limiting fixation during the cable layout process are realized, so that the power monitoring lines can be arranged neatly and orderly, significantly improving the standardization of the cable routing and the ability to install quickly, and reducing the messy and difficult-to-identify cable routing in traditional monitoring cabinets.

[0017] 2. In this utility model, the wire-clamping assembly adopts a locking structure consisting of two sets of opposing interlocking slotted parts, spring-loaded ears, and slots, combined with a secondary locking design formed by the ear clips and the hand ring. This not only ensures a secure connection and prevents loosening during operation but also facilitates quick unlocking and resetting during maintenance or line replacement. Furthermore, the entire assembly is made of flame-retardant engineering plastic material, effectively improving high-temperature resistance and flame-retardant performance, thus enhancing the safety and reliability of the device in the power station operating environment.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of a power station monitoring device provided by this utility model.

[0030] Combination Figures 1-5 As shown, this utility model provides a power monitoring device for a power supply station, including a monitoring cabinet 100, cable trays 200, cable clamping components 300, and a monitor 110 fixed inside the monitoring cabinet 100. The monitoring cabinet 100 is used to install, support, and protect the internal wiring and monitoring equipment. Several cable trays 200 are arranged parallel to the direction of the power lines on its inner wall surface, providing a flat mounting surface for the wiring. The monitor 110 is fixed in an appropriate position inside the monitoring cabinet 100 to realize real-time acquisition and monitoring of power operation data of the power supply station.

[0031] In this embodiment, several cable trays 200 are arranged parallel to each other along the cable routing direction and installed on the inner wall surface of the monitoring cabinet 100, so that multiple sets of cables can be arranged in segments along the cable trays 200. Cable clamping assemblies 300 are slidably installed inside the monitoring cabinet 100, and adjacent cable clamping assemblies 300 are connected in parallel, ensuring cable fixation while achieving multi-segment interlocking and preventing cable detachment. Each cable clamping assembly 300 includes two sets of opposing engaging clamping slots 310 and positioning blocks 320. The positioning blocks 320 are rotatably mounted on one side of the clamping slots 310, allowing for position adjustment during installation. The surface of the clamping slots 310 is provided with cable grooves for positioning the cable bundles, and on both sides of the cable grooves are respectively provided grooves 311 and spring-loaded lugs 312 that are adapted to their shapes. The two clamping slots 310 are interlocked through the grooves 311 and spring-loaded lugs 312 to achieve a stable clamping effect. One side of the spring-loaded ear 312 is provided with an ear clip 330. The adjacent wire-fastening assembly 300 can be connected by the ear clip 330 on the surface of the spring-loaded ear 312 to achieve continuous wiring and anti-detachment function.

[0032] In this embodiment, the surface of the cable board 200 is provided with a slide rail 201 for supporting the sliding of the positioning block 320. The surface of the slide rail 201 is provided with a positioning wave protrusion 202, which can elastically abut against the inner side of the positioning block 320, thereby achieving precise positioning and limiting of the positioning block 320 and the wire fastening assembly 300, and preventing the wire fastening assembly 300 from shifting during operation.

[0033] In this embodiment, the cross-section of the spring-loaded ear 312 is mushroom-shaped, and a deformation gap is provided in the middle. The cross-sectional shape of the groove 311 is adapted to the spring-loaded ear 312, so that after the spring-loaded ear 312 is inserted into the groove 311, it can automatically limit and prevent detachment by relying on the mushroom-shaped cross-section, thus avoiding loosening caused by vibration.

[0034] In this embodiment, the ear clips 330 are fixed on the surface of the spring-loaded ear 312, and the ear clips 330 are symmetrically distributed about the deformation gap. During operation, the ear clips 330 can be controlled to move closer to each other, thereby realizing the deformation of the spring-loaded ear 312, which makes it easy to unlock and remove it from the groove 311, thus meeting the needs of disassembly and maintenance.

[0035] In this embodiment, the surface of the ear loop 330 is provided with a buckle ring 331. When adjacent buckle wire assemblies 300 are installed in parallel, the ear loops 330 can hook each other, and the buckle rings 331 are arranged coaxially with overlapping. When in use, the buckle rings 331 can be inserted into the locking pin to achieve secondary locking, thereby significantly improving the vibration resistance and connection stability.

[0036] In this embodiment, the surface of the positioning block 320 is provided with a pin that connects to the surface of the fastening slot 310. The pin provides an additional fixing point when the fastening slot 310 is rotated or installed, further improving the overall stability of the fastening assembly 300.

[0037] In this embodiment, the entire wire fastening assembly 300 is made of flame-retardant engineering plastic material, which gives it good high temperature resistance and flame retardant properties in the power station operating environment, effectively reducing the risk of fire caused by short circuit or overheating and improving the operational safety of the device.

[0038] In the specific use of this utility model, the monitoring cabinet 100 is first fixedly installed at a preset position in the power supply station, and several cable trays 200 are installed on its inner wall surface along the cable routing direction. Then, the cable clamping assembly 300 is slidably installed onto the cable tray 200 along the slide rail 201, so that the positioning block 320 and the positioning corrugated 202 elastically abut against each other to achieve positioning. When wiring, the power monitoring line is placed into the cable groove of the clamping slot 310, and locked by the insertion and cooperation of the slot 311 and the spring-loaded ear 312; if line maintenance or replacement is required, the ear buckle 330 can be pressed or the locking pin on the buckle ring 331 can be pulled out, so that the spring-loaded ear 312 deforms and disengages from the slot 311, which is convenient for disassembly and rewiring.

[0039] Working principle and usage process of this utility model:

[0040] The present invention relates to a power monitoring device for a power supply station. During installation and use, the monitoring cabinet 100 is first fixed in a preset position in the power supply station. Several cable trays 200 are arranged parallel to the cable routing direction on the inner wall surface of the monitoring cabinet 100. Several cable clipping components 300 are pre-installed on the surface of the cable trays 200. The surface of the cable trays 200 is provided with slide rails 201 and positioning corrugations 202, which are used to provide guidance and positioning functions for the subsequent installation of the cable clipping components 300.

[0041] When installing power monitoring lines, the operator can slide the bottom of the cable clamping assembly 300 along the slide rail 201 into the monitoring cabinet 100, and make the inner side of the positioning block 320 elastically abut against the positioning corrugation 202 to achieve positioning and limiting of each cable clamping assembly 300. The cable clamping assembly 300 includes two sets of opposing engaging clamping slots 310. The surface of the clamping slot 310 is provided with a groove for accommodating cables, and a receiving groove 311 and a spring-loaded ear 312 are respectively provided on both sides. The spring-loaded ear 312 is inserted into the receiving groove 311, and the mushroom-shaped cross section and deformation gap structure features are used to achieve automatic limiting and locking to prevent loosening during operation.

[0042] When connected to the relative fastener 310, the ear buckle 330 and the deformation gap can achieve deformation control of the spring ear 312, which is convenient for unlocking and separation. The ear buckle 330 can also be hooked together and the buckle ring 331 overlaps and is coaxial when adjacent buckle wire assemblies 300 are installed in parallel. Secondary locking can be achieved by inserting a locking pin, which further improves the connection reliability and vibration resistance.

[0043] When it is necessary to lay or replace the line, the operator can press the ear clip 330 or pull out the locking pin through the buckle ring 331 to deform the spring connector 312 and separate it from the connector groove 311, thereby separating the groove component 310. After the cable is placed into the groove, the groove component 310 is reset and locked, realizing fast and reliable line arrangement and fixation.

[0044] During operation, the flame-retardant engineering plastic wire-clamping assembly 300 effectively enhances high-temperature resistance and flame-retardant safety performance, preventing fire risks caused by internal overheating or short circuits in the power supply station. The overall structure enables orderly arrangement, rapid identification, convenient maintenance, and safety protection of power monitoring lines, thereby ensuring the long-term stable operation of the power station's power monitoring system.
