Description

Technical Field

[0001] This utility model relates to the field of indicator light detection technology, and more specifically, to a 400V indicator light rapid detection device. Background Technology

[0002] In power systems and industrial equipment, 400V indicator lights are critical status indicators, widely used in distribution cabinets, relay protection devices, and high-voltage equipment. Their operational reliability directly impacts equipment safety and fault diagnosis efficiency. To ensure the correct use and effective installation of 400V indicator lights, a power-on test must be performed before replacement. Traditional testing methods typically rely on adjustable power generators to simulate actual voltage environments, manually plugging and unplugging the indicator lights one by one for illumination testing. However, these methods often use exposed metal contacts or open terminals, requiring operators to directly contact live parts when plugging and unplugging the indicator lights. This can lead to accidents such as short circuits or arc discharges due to accidental contact or slipping tools. Furthermore, with the expansion of power company equipment and the increased production capacity of indicator light manufacturers, existing testing technologies are insufficient to meet the demands of large-scale, high-precision, and high-efficiency testing. Limited by single-piece workflows and lack of safety protection, they are ill-suited to the industry's large-scale, standardized testing requirements. Utility Model Content

[0003] The purpose of this invention is to provide a rapid testing device for 400V indicator lights, which achieves efficient batch testing of 400V indicator lights and inherently safe operation. It combines high precision, ease of use and environmental adaptability, providing the industry with a standardized and large-scale testing solution.

[0004] The embodiments of this utility model are achieved through the following technical solutions: A 400V indicator light rapid detection device includes a housing; the housing is provided with an AC power input module, a single-phase rectifier module, a load, and indicator light detection terminals; one output terminal of the AC power input module is connected to the input terminal of the single-phase rectifier module, the output terminal of the single-phase rectifier module is connected to the input terminal of the load, the output terminal of the load is connected to the indicator light detection terminals, and multiple indicator light detection terminals are provided for connecting 400V indicator lights.

[0005] By integrating multi-channel indicator light detection terminals, multiple indicator lights under test can be connected simultaneously. Combined with the coordinated control of the rectifier module and the load, multiple sets of 400V indicator lights can be tested in parallel at one time. At the same time, an AC power input module and a single-phase rectifier module are installed to meet the test voltage requirements of various indicator lights. The device adopts an integrated protective enclosure, which encapsulates the AC power input module, single-phase rectifier module and live terminals inside, completely isolating the operator from direct contact with exposed conductors.

[0006] Optionally, it also includes a power switching switch, with another output terminal of the AC power input module connected to one switching port of the power switching switch, the output terminal of the load connected to another switching port of the power switching switch, and the common port of the power switching switch connected to the indicator light detection terminal.

[0007] By adding a power switching switch, the device can quickly switch between AC power (direct input) and rectified DC power without changing wiring or external equipment. During the switching process, the power supply of the circuit to be switched is automatically cut off to avoid the risk of live operation.

[0008] Optionally, a micro switch is also included, wherein the common port of the power switching switch is connected to the input port of the micro switch, and the output port of the micro switch is connected to the indicator light detection terminal.

[0009] The microswitch design further enhances the safety and operational reliability of the device by precisely controlling the on / off state of the detection circuit.

[0010] Optionally, it also includes a first voltage monitoring device, with another output terminal of the AC power input module connected to the input terminal of the first voltage monitoring device, and the output terminal of the first voltage monitoring device connected to a switching port of the power switching switch.

[0011] The first voltage monitoring device is directly connected to the AC power input module, which can collect and display the input voltage value in real time. The first voltage monitoring device integrates data storage and output interfaces, and can record the input voltage waveform, effective value and fluctuation rate for each test.

[0012] Optionally, a second voltage monitoring device is also included, wherein the output terminal of the load is connected to the input terminal of the second voltage monitoring device, and the output terminal of the second voltage monitoring device is connected to the indicator light detection terminal.

[0013] The second voltage monitoring device directly collects the DC voltage signal output from the single-phase rectifier module to the indicator light, forming a bidirectional calibration mechanism with the first voltage monitoring device. When the output voltage of the rectifier module deviates due to sudden load changes or temperature drift, the device can collect voltage data in real time through the first and second voltage monitoring devices. Based on the voltage data, the operator can adjust the load parameters or trigger the compensation circuit to ensure that the indicator light under test is always in a standard voltage environment and avoid misjudgment caused by power fluctuations.

[0014] Optionally, the load is a DC voltage regulator.

[0015] The DC voltage regulator supports continuous voltage adjustment. The target test voltage value can be quickly set through the knob or digital control interface without replacing the hardware or connecting an external voltage divider module.

[0016] Optionally, it also includes a switching device, wherein the output terminal of the AC power input module is connected to the input terminal of the switching device, one output terminal of the switching device is connected to the single-phase rectifier module, and the other output terminal of the switching device is connected to a switching port of the power switching switch.

[0017] As the core distribution node for AC power input, the switching device can independently choose to deliver power to the rectifier module or directly to the power switching switch. When switching power paths, it ensures that the unselected path is completely physically isolated, avoiding the risk of accidental crosstalk or short circuit between AC and DC circuits.

[0018] Optionally, the box is provided with a partition, which is placed horizontally. The partition includes an upper partition and a lower partition. The upper partition has a circular hole, and the lower partition has the indicator light detection terminal, which is installed at the bottom of the circular hole.

[0019] There is a gap between the upper and lower partitions. A single-phase DC voltage regulator that does not need to be exposed is installed on the left side of the lower partition, and an indicator light detection terminal is installed on the right side. Twenty M3 screws are fixed and divided into 10 groups and installed on the lower partition as indicator light test socket contacts. Components that need to be displayed or operated, such as voltmeters, power switches and DC voltage regulators, are installed on the left side of the upper partition, and round holes are provided on the right side corresponding to the indicator light detection terminals.

[0020] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects: During testing, this device only requires connecting the indicator light through an external insulated connector, eliminating the need to open the enclosure or touch high-voltage components. This fundamentally avoids the safety hazards of electric shock and short circuits caused by exposed contacts in traditional equipment. Through multi-channel testing, enclosed protection, and modular design, this solution achieves efficient batch testing and inherently safe operation of 400V indicator lights. It combines high precision, ease of use, and environmental adaptability, providing the industry with a standardized and large-scale testing solution. Attached Figure Description

Detailed Implementation

[0022] 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 embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] like Figure 1 As shown, this utility model provides one embodiment: a 400V indicator light rapid detection device, including a housing; the housing is provided with an AC power input module, a single-phase rectifier module, a load, and indicator light detection terminals; one output terminal of the AC power input module is connected to the input terminal of the single-phase rectifier module, the output terminal of the single-phase rectifier module is connected to the input terminal of the load, the output terminal of the load is connected to the indicator light detection terminals, and multiple indicator light detection terminals are provided, which are used to connect 400V indicator lights.

[0024] In this embodiment, compared with the traditional manual plugging and unplugging method, the detection efficiency of this device is improved several times. It is especially suitable for large-scale equipment maintenance in power companies or batch calibration of indicator light manufacturers. During the test, the indicator light only needs to be connected through the external insulated socket. There is no need to open the box or touch the high-voltage components. This fundamentally avoids the safety hazards of electric shock and short circuit caused by exposed contacts in traditional equipment. Through multi-channel detection, closed protection and modular design, this solution realizes efficient batch detection and inherently safe operation of 400V indicator lights. It has high precision, ease of use and environmental adaptability, and provides the industry with a standardized and large-scale detection solution.

[0025] More specifically, it also includes a power switching switch, with another output terminal of the AC power input module connected to one switching port of the power switching switch, the output terminal of the load connected to another switching port of the power switching switch, and the common port of the power switching switch connected to the indicator light detection terminal.

[0026] During implementation, operators can flexibly select test modes according to the indicator light types such as AC, DC, or AC / DC dual-use, ensuring compatibility testing of products of different specifications, avoiding the time-consuming repetitive configuration under the traditional single power supply mode, significantly improving the adaptability to multiple scenarios, and at the same time, the switch status is fed back in real time through external indicator lights or displays to prevent accidental touches or incorrect mode selection. While improving safety and operational efficiency, it meets the diverse testing needs under complex working conditions.

[0027] In a further application of this embodiment, a micro switch is also included, wherein the common port of the power switching switch is connected to the input port of the micro switch, and the output port of the micro switch is connected to the indicator light detection terminal.

[0028] In practice, the micro switch is installed on one side inside the enclosure. The micro switch is normally open. The enclosure also includes a cover. When the cover is closed, it contacts the micro switch, causing the micro switch to close and thus connecting the detection circuit. This prevents electric shock to personnel. While ensuring the safety of the detection environment, it optimizes the detection accuracy and process efficiency, providing a highly reliable and intelligent hardware foundation for high-voltage indicator light detection. like Figure 4 As shown, a transparent observation window can be installed on the box cover at the position of the round hole, which makes it convenient for operators to observe during the testing process.

[0029] Specifically, it also includes a first voltage monitoring device, with another output terminal of the AC power input module connected to the input terminal of the first voltage monitoring device, and the output terminal of the first voltage monitoring device connected to a switching port of the power switching switch.

[0030] In this embodiment, the first voltage monitoring device, in conjunction with threshold settings, manually or automatically cuts off the power supply when the voltage exceeds the limit. For example, if grid fluctuations cause the input voltage to drop below 360V, the testing process is immediately terminated to avoid the 400V indicator light being under-tested due to insufficient voltage caused by abnormal power supply, thus preventing misjudgment as "non-compliant." It also prevents damage to the rectifier module due to prolonged undervoltage operation, significantly improving the stability of the testing environment and the lifespan of the equipment. Furthermore, long-term voltage data can be used to analyze power supply quality, providing a reference for equipment operation and maintenance. The introduction of the first voltage monitoring device enables full-cycle monitoring and intelligent response of the input power status. While ensuring testing accuracy, equipment safety, and compliance, it expands the applicability of the device in complex power supply scenarios, providing key technical support for high-reliability testing.

[0031] Furthermore, it also includes a second voltage monitoring device, the output terminal of the load is connected to the input terminal of the second voltage monitoring device, and the output terminal of the second voltage monitoring device is connected to the indicator light detection terminal.

[0032] When testing multiple indicator lights in parallel, differences in load across channels may cause uneven output voltage distribution. The second voltage monitoring device monitors the DC circuit independently for each channel, identifies abnormal voltage circuits in real time, and automatically isolates faulty channels or activates dynamic voltage equalization strategies to ensure that the testing of other channels is not disturbed. This improves testing accuracy, batch testing consistency, and equipment safety levels, while providing data support for quality management and operation and maintenance decisions.

[0033] More specifically, the load is a DC voltage regulator.

[0034] This embodiment replaces the load with a DC voltage regulator, which introduces high-precision voltage regulation capability and dynamic response characteristics, significantly optimizing the testing flexibility and output stability of the detection device.

[0035] In a specific application of this embodiment, a switching device is also included. The output terminal of the AC power input module is connected to the input terminal of the switching device, one output terminal of the switching device is connected to the single-phase rectifier module, and the other output terminal of the switching device is connected to a switching port of the power switching switch.

[0036] When the rectifier module fails or requires maintenance, it can be quickly switched to AC direct-drive mode via a switching device to maintain basic testing functions. The introduction of the switching device creates a flexible, safe, and efficient power distribution network. While ensuring multi-mode testing compatibility and system reliability, it optimizes energy efficiency through intelligent scheduling, providing a highly adaptable solution for indicator light testing under complex operating conditions. like Figure 2 , Figure 3 As shown, the box is equipped with a partition, which is placed horizontally. The partition includes an upper partition and a lower partition. The upper partition has a circular hole, and the lower partition has the indicator light detection terminal, which is installed at the bottom of the circular hole.

[0037] In practice, the round hole left in the upper partition and the contact installed on the lower partition form the indicator light mounting base. By adjusting the gap between the two partitions, the indicator light can be placed in the round hole in the upper partition. Under its own weight, the wiring terminal of the indicator light is pressed against the contact fixed to the lower partition.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
