Description

Technical Field

[0001] This utility model relates to the field of power system equipment testing devices, and in particular to a relay action analyzer. Background Technology

[0002] A relay action analyzer is a specialized instrument used to test the action characteristics of relays. It can measure and analyze parameters such as the relay's action value, return value, and action time, ensuring the reliable operation of relays in power systems and other fields. It can measure key parameters such as the relay's action value, return value, and action time. For example, the LY660 microprocessor-based relay action characteristic tester can measure relevant parameters of voltage protection, current protection, synchronous relays, DC relays, and intermediate relays.

[0003] This system displays real-time information such as current and voltage power values, sequence components, vector diagrams, and waveforms, and records relevant data. It can display various parameters in real time and record data in COMTRADE format for fault playback. Typically based on microcontroller control technology, it provides variable voltage or current to the relay under test through a step-up / step-down or current-step-up circuit. Taking voltage-type relay testing as an example, during the step-up process, the voltage detection module detects the voltage and feeds it back to the microcontroller. The contact detection module monitors the contact status. When the contact actuates, the microcontroller records the voltage value at that moment, which is the operating voltage. Similarly, it can test the step-down operating voltage, the operating current of current-type relays, etc., and can also calculate the operating time.

[0004] Relay action analyzers have the following drawbacks: relays of different brands and models have large differences in parameters, and the output range of some analyzers, such as voltage, current or interface type, is fixed, making it difficult to adapt to relays of special specifications, resulting in test errors or failure to test. Therefore, a relay action analyzer is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of a relay action analyzer, comprising an analyzer body 1 and an operation panel 2. The operation panel 2 is fixedly connected to the top outer wall of the analyzer body 1. A display screen frame 3 is hinged to the top inner wall of the analyzer body 1. A snap-fit ​​assembly 4 is fixedly installed on the front inner wall of the analyzer body 1. An adjustment mechanism 5 and an auxiliary mechanism 6 are provided on the analyzer body 1. The adjustment mechanism 5 includes a plug-in module 51, which provides a connection base for an expansion interface frame 53, achieving a stable connection between the two. The plug-in module 51 is fixedly connected to the top inner wall of the analyzer body 1. The top outer wall of the instrument body 1 is provided with a positioning groove 52. The positioning groove 52 guides and limits the sliding of the expansion interface frame 53, ensuring the stability of the movement of the expansion interface frame 53. The expansion interface frame 53 is slidably connected to the inner walls of the front and rear sides of the positioning groove 52. A bayonet 54 is provided on the right outer wall of the expansion interface frame 53. An L-shaped plate 55 is slidably connected to the top inner wall of the analyzer body 1. An arc-shaped plate 56 is fixedly connected to the left outer wall of the L-shaped plate 55. The arc-shaped plate 56 is inserted into the bayonet 54 to fix the expansion interface frame 53 in the positioning groove 52 to prevent it from loosening. A compression spring 57 is fixedly connected to the right outer wall of the L-shaped plate 55.

[0024] Reference Figures 2-4 The display frame 3 is snapped onto the inner front wall of the buckle assembly 4. The expansion interface frame 53 is inserted into the inner top wall of the plug-in module 51. The expansion interface frame 53 and the plug-in module 51 are plugged into each other to achieve electrical connection and mechanical fixation. A frosted pad is fixedly connected to the outer top wall of the L-shaped plate 55. The frosted pad increases the friction when the L-shaped plate 55 is pushed by the operator, making it easier to operate. The end of the compression spring 57 away from the L-shaped plate 55 is fixedly connected to the inner right side wall of the analyzer body 1. Wear-resistant sleeves are fixedly connected to the outer side walls of the arc plate 56 and the bayonet 54. The wear-resistant sleeves reduce the wear between the arc plate 56 and the bayonet 54 and extend the service life of both. The arc plate 56 is snapped onto the inner right side wall of the bayonet 54.

[0025] Reference Figures 3-4The auxiliary mechanism 6 includes a limiting rod 61, which is hinged to the left inner wall of the analyzer body 1. A belt 62 is fixedly connected to the outer side wall of the limiting rod 61, which allows personnel to carry the analyzer body 1 by hand or over their shoulder. A sliding plate 63 is slidably connected to the top inner wall of the analyzer body 1. A telescopic spring 64 is fixedly connected to the left outer wall of the sliding plate 63, and a pin 65 is fixedly connected to the right outer wall of the sliding plate 63. The pin 65 is inserted into the adjustment port 66 to fix the length of the belt 62. An adjustment port 66 is opened on the right inner wall of the belt 62. A silicone pad is fixedly connected to the top outer wall of the sliding plate 63 to increase the comfort and friction when personnel pull the sliding plate 63. The end of the telescopic spring 64 away from the sliding plate 63 is fixedly connected to the top inner wall of the analyzer body 1. There are several adjustment ports 66, which are respectively opened on the right inner wall of the belt 62. The pin 65 is engaged with the right inner wall of the adjustment port 66.

[0026] Working principle: By connecting the corresponding model expansion interface frame 53 to the plug-in module 51, it can adapt to the detection of relays of different specifications. When the interface needs to be upgraded or replaced, simply push the L-shaped plate 55 to move the arc plate 56. The arc plate 56 moves and separates from the bayonet 54. Then pull the expansion interface frame 53 to separate from the plug-in module 51 for replacement or maintenance of the expansion interface frame 53. This avoids the problem of a single fixed interface adapting to a limited number of relay types. After the whole analyzer is used up, the display frame 3 and the analyzer body 1 are closed and locked by the buckle assembly 4. Then, it can be conveniently carried by hand using the belt 62. When it is inconvenient for personnel to carry it by hand, the sliding plate 63 is pulled to move the pin 65. The pin 65 moves and separates from the adjustment port 66. Then, the belt 62 is pulled to expand to the length of the personnel's shoulder bag strap. The analyzer body 1 is carried in a shoulder bag style with the belt 62 tucked under the shoulder, eliminating the need for personnel to carry it by hand.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
