Description

Technical Field

[0001] This utility model relates to the field of insulation withstand voltage testing technology for insulating equipment, and specifically discloses a high-voltage insulation testing assembly. Background Technology

[0002] In the field of power operations, high-voltage insulation tools such as insulating rods, insulating gloves, and insulating shoes are critical equipment for ensuring the safety of operators. To ensure reliable insulation performance, high-voltage withstand voltage tests must be conducted strictly according to the prescribed schedule. Currently, the traditional high-voltage insulation testing equipment widely used in the industry has the following significant drawbacks:

[0003] Existing equipment typically only allows for serial testing of single insulating items (such as an insulating rod or a pair of gloves). When faced with a large number of items to be tested, repetitive and tedious single-item operations must be performed, resulting in extremely low testing efficiency and significant manpower and time costs.

[0004] Existing equipment, especially test racks for insulating rods, has a fixed structure and cannot be flexibly adjusted to accommodate batch testing of insulating rods of different lengths, diameters, or quantities. When testing non-standard sizes or multiple insulating rods is required, existing equipment is often inadequate or requires complex modifications.

[0005] The setting of test parameters, process monitoring, and data recording rely heavily on manual operation and judgment, which is cumbersome and increases the risk of human error, making it difficult to meet the needs of efficient and accurate testing.

[0006] The inefficient serial testing mode results in low equipment utilization, relatively high energy consumption, and requires a large amount of repetitive manual labor, which does not meet the current industry development requirements of energy conservation, emission reduction, quality improvement and efficiency enhancement.

[0007] Therefore, there is an urgent need to develop a new type of high-voltage insulation testing combination device that can overcome the above-mentioned defects and realize efficient, safe, and batch parallel testing of different types (such as insulating rods and insulating gloves / shoes), different sizes, and different quantities of high-voltage insulation tools. This would significantly improve testing efficiency, reduce labor costs and energy consumption, and meet the growing demand for large-scale and standardized testing in the power industry. Utility Model Content

[0008] This utility model proposes a high-voltage insulation test assembly device. Through the reasonable combination of various components, it can realize batch testing of various high-voltage insulation products. It can flexibly adapt to test samples of different sizes and quantities, improve test efficiency, reduce labor intensity and cost, and has practical application value of safety, stability, cost reduction and efficiency improvement.

[0009] This utility model is implemented as follows: a high-voltage insulation test assembly device, comprising:

[0010] Intelligent high-voltage testing equipment, test high-voltage transformer, high-voltage insulating rod test frame, high-voltage insulation test chamber;

[0011] A high-voltage standard voltmeter is installed below the test high-voltage transformer;

[0012] The top of the high-voltage insulating rod test frame is the conductor part of the test insulating rod, and both ends of the conductor part of the test insulating rod are provided with high-voltage wire junction box fixing screws and matching nuts;

[0013] Two high-voltage insulating rods are vertically fixed to both ends of the conductor section of the test insulating rod and connected by a locking device at the upper end;

[0014] The bottom of the high-voltage insulating rod is connected to a ground balance fixing bracket, and both ends of the ground balance fixing bracket are provided with widened stabilizing brackets.

[0015] In a preferred embodiment of the high-voltage insulation test assembly of this utility model, the high-voltage standard voltmeter is located directly below the test high-voltage transformer and is used to display the test voltage value in real time.

[0016] As a preferred embodiment of the high-voltage insulation test assembly of this utility model, the longitudinal position of the high-voltage insulation rod test frame is adjustable to accommodate the installation of insulation rods of different lengths.

[0017] As a preferred embodiment of the high-voltage insulation test assembly of this utility model, the transverse width of the high-voltage insulation rod test frame can be expanded to accommodate multiple insulation rods for parallel testing.

[0018] As a preferred embodiment of the high-voltage insulation test assembly of this utility model, the high-voltage insulation rod test frame is composed of two independent supports, and the spacing can be freely adjusted.

[0019] As a preferred embodiment of the high-voltage insulation test assembly of this utility model, the high-voltage insulation test chamber and the high-voltage insulation rod test frame are connected in parallel in the high-voltage circuit to achieve synchronous testing of the insulation rod and the insulation gloves / insulation shoes.

[0020] As a preferred embodiment of the high-voltage insulation test combination device of this utility model, the intelligent high-voltage test device integrates a parameter setting module, which supports preset test voltage and duration and data printing functions.

[0021] The beneficial effects of this utility model are:

[0022] Through modular parallel design (linking the high-voltage insulation rod test frame with the high-voltage insulation test chamber) and expandable structure (free adjustment in the longitudinal and lateral directions), synchronous batch testing of insulation rods, insulation gloves, and insulation shoes is achieved, increasing testing efficiency by more than 60%. Its dual-stabilized support and mechanical locking device ensure operational safety under 45kV high voltage, while the intelligent integrated control system automates parameter setting and data recording, significantly reducing labor costs and energy consumption. This device solves the problems of low efficiency and poor adaptability of traditional equipment for single-piece serial testing, and has the core advantages of high efficiency, safety, and flexibility.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1 and 2 A high-voltage insulation test assembly, comprising:

[0029] Intelligent high voltage testing device 1, test high voltage transformer 2, high voltage insulation rod test frame 3, high voltage insulation test chamber 4;

[0030] A high-voltage standard voltmeter 5 is installed below the test high-voltage transformer 2;

[0031] The top of the high-voltage insulating rod test frame 3 is the test insulating rod conductor part 6, and the two ends of the test insulating rod conductor part 6 are equipped with high-voltage wire junction box fixing screws 7 and matching nuts 8;

[0032] Two high-voltage insulating rods 9 are vertically fixed to both ends of the conductor section 6 of the test insulating rod and connected by the locking device 10 at the upper end;

[0033] The bottom of the high-voltage insulating rod 9 is connected to a ground balance fixing bracket 11, and the two ends of the ground balance fixing bracket 11 are provided with widened stabilizing brackets 12.

[0034] In this embodiment: After the intelligent high-voltage test device 1 presets parameters such as test voltage (e.g., 45kV) and duration (e.g., 1min), it sends a command to the test high-voltage transformer 2. The high-voltage test transformer boosts the voltage to the set value and connects to the conductor part 6 of the test insulating rod through the high-voltage wire, screw, and nut 8 to form a high-voltage test circuit.

[0035] Sample installation and support:

[0036] The insulating rod to be tested is fixed to the conductor part 6 of the test insulating rod of the high-voltage insulating rod test frame 3 and is fixed to the high-voltage insulating rod 9 by the locking device 10; the insulating gloves / shoes are placed in the high-voltage insulation test chamber 4 and the two are connected in parallel to the high-voltage circuit; the ground balance fixing bracket 11 and the widened stabilizing bracket 12 ensure that the entire device is stable and does not tip over under high-voltage conditions.

[0037] Voltage monitoring and safety mechanisms:

[0038] The high-voltage standard voltmeter 5 displays the transformer output voltage in real time. If the voltage is abnormal or the test sample breaks down, the intelligent device will immediately trigger an alarm and cut off the power supply to prevent the accident from escalating. The high-voltage insulating rod 9 isolates the conductor from the ground to ensure the safety of the operators.

[0039] As a technical optimization of this utility model, the high-voltage standard voltmeter 5 is located directly below the test high-voltage transformer 2 and is used to display the test voltage value in real time.

[0040] In this embodiment, the operator can directly view the voltage data and adjust the parameters in a timely manner; at the same time, it avoids test deviations caused by voltage display lag.

[0041] As a technical optimization of this utility model, the longitudinal position of the high-voltage insulating rod test frame 3 is adjustable to accommodate the installation of insulating rods of different lengths.

[0042] In this embodiment, the longitudinal position of the high-voltage insulating rod test frame 3 is adjustable, which is compatible with testing insulating rods of different lengths from 1 to 5m without the need to replace the equipment; this reduces the cost of customized brackets and improves the versatility of the equipment.

[0043] As a technical optimization of this utility model, the lateral width of the high-voltage insulating rod test frame 3 can be expanded to accommodate multiple insulating rods for parallel testing.

[0044] In this embodiment, the horizontal width of the high-voltage insulating rod test frame 3 is expandable, which can accommodate multiple insulating rods. 5-10 insulating rods can be placed at the same time in a single test, which is 5 times more efficient than traditional equipment. Moreover, the modular expansion structure supports increasing the number of tests as needed.

[0045] As a technical optimization of this utility model, the high-voltage insulating rod test frame 3 is composed of two independent supports, and the spacing can be freely adjusted.

[0046] In this embodiment, the device is adapted to insulating rods of different diameters (e.g., 30-80mm), and the spacing is adjusted to ensure stable installation, thus flexibly meeting the testing needs of irregularly shaped samples.

[0047] As a technical optimization of this utility model, the high-voltage insulation test chamber 4 and the high-voltage insulation rod test frame 3 are connected in parallel in the high-voltage circuit to realize the synchronous testing of the insulation rod and the insulation gloves / insulation shoes.

[0048] In this embodiment, the high-voltage insulation test chamber 4 and the high-voltage insulation rod test frame 3 are connected in parallel, which can simultaneously test multiple types of test samples, saving more than 60% of the test time. They also share a high-voltage power supply, reducing equipment energy consumption and floor space.

[0049] As a technical optimization of this utility model, the intelligent high-voltage testing device 1 integrates a parameter setting module, which supports preset test voltage and duration and data printing functions.

[0050] In this embodiment: the intelligent high-voltage testing device 1 integrates parameter setting and data printing functions, and can preset standard test parameters (such as the withstand voltage value specified in GB / T1408.1) with one click, and automatically generate test reports, which comply with the quality inspection standards of the power industry.

[0051] Working principle and usage process of this utility model:

[0052] Ground-level balancing support 11 and widened stabilizing support 12 ensure the stability of the high-voltage insulation rod test frame 3; adjust the high-voltage insulation rod test frame 3 according to the number / size of the test samples, adjusting the rod position longitudinally, expanding the width laterally, and adjusting the spacing between the double high-voltage insulation rod test frames 3; insert the insulation rod into the slot of the high-voltage insulation rod component 9 and fix it with the locking device 10, and crimp the wires through the screw / nut 8; place gloves / shoes inside the high-voltage insulation test chamber 4 and connect them to the internal electrodes; set the test voltage, duration, and other parameters through the intelligent high-voltage test device 1; start the test, the high-voltage test transformer outputs high voltage, and the high-voltage standard voltmeter 5 displays the value in real time; the high-voltage insulation rod test frame 3 and the high-voltage insulation test chamber 4 work synchronously, monitoring and recording; the intelligent high-voltage test device 1 automatically monitors the leakage current / withstand voltage time, and automatically cuts off the power and alarms if an abnormality occurs; after the test, the high-voltage test transformer is reduced to zero, the power is cut off, and the intelligent high-voltage test device 1 automatically generates and prints a report, which includes data such as voltage, time, and test results.
