The creeping current and the number of times are recorded. When it is monitored that the creeping of the control cabinet is relatively frequent, the test process is automatically started to detect the reliability of the creeping protection switch, so that the timely response performance is effectively ensured. When the test result shows that the creeping protection switch has a fault, the creeping situation is comprehensively judged by combining the creeping current and the visual data of the visual load, and the opening of the creeping protection switch is realized through a two-shaft sliding rail and a dynamic frame, so that the risk of electric shock is effectively reduced.

Description

Technical Field

[0001] The present invention relates to an electric control cabinet, in particular to an electric control cabinet with an anti-leakage function applied in the field of power distribution. Background Art

[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-enclosed metal cabinet or on a screen according to electrical wiring requirements. During normal operation, it can connect or disconnect circuits using manual or automatic switches. In the event of a fault or abnormal operation, protective devices can disconnect the circuit or generate an alarm.

[0003] A leakage protector, also known as a leakage switch or leakage circuit breaker, is mainly used to protect equipment from leakage faults and to protect people from fatal electric shock. It has overload and short-circuit protection functions and can be used to protect lines or motors from overload and short circuit. It can also be used as an infrequent switching starter for lines under normal circumstances.

[0004] Chinese patent CN117477385B discloses a leakage detection device for a distribution cabinet. The lock tongue slides by rotating a control handle, and the control handle controls the rotation of a distribution plate through a control rod. The rotating distribution plate is respectively connected to the protection terminal and the power-off terminal to control the flow direction of the leakage current. The control resistance reduces the current transmitted to the ground wire to be less than the reaction current of the leakage protector, resulting in no reaction of the leakage protector and the display lamp bead lighting up. When the staff finds that the display lamp bead is lighting up, time can be left to protect the machinery and equipment in the workshop, thereby reducing the risk of equipment damage caused by leakage tripping.

[0005] Chinese patent CN111181031B discloses an electrical cabinet with a power-off protection mechanism, which solves the problem that most electrical cabinets on the market use insulation to prevent leakage, but this cannot solve the root problem, and the leakage phenomenon still exists. In addition, the electrical cabinet will accumulate dust over time, and the dust will cause insulation and affect the use of electrical components.

[0006] In the prior art, leakage protectors are generally used to monitor leakage in electrical cabinets and provide power-off protection. However, leakage protectors need to be regularly tested for reliability every month. By manually pressing a test button to simulate a leakage fault, the protection function is verified to be normal. After pressing the button, if the leakage protector can trip quickly, it means it is normal. If it cannot trip, there may be a fault and it needs to be repaired in time. However, this method will disconnect the power supply and electrical components, causing the electrical components to stop operating due to power outages. In addition, this method also has the defect of insufficient testing frequency, making it difficult to respond to sudden failures of the leakage protector in a timely manner. If manual operations are too frequent, a lot of manpower will be consumed. Summary of the Invention

[0010] When the cabinet is subjected to reliability testing, the first transfer switch and the second transfer switch are automatically activated, so that the leakage protection switch transmits power to the test load through the first transfer switch, and the backup power supply transmits power to the power consumption end through the second transfer switch;

[0011] A hardware auxiliary unit is provided inside the cabinet, which includes a pair of two-axis slide rails and a dynamic frame installed between the pair of two-axis slide rails. The dynamic frame includes a horizontal plate, a protruding plate is fixedly connected to the end of the horizontal plate close to the leakage protection switch, an electric motor is fixedly connected to the upper end of the horizontal plate, a rotating shaft is fixedly connected to the output end of the motor, and a dynamic plate is fixedly connected to the outer end of the rotating shaft;

The leakage protection switch is connected to the leakage protection module, the two-axis slide rail, the first conversion switch and the second conversion switch are all connected to the automatic test module, and the motor is connected to the secondary protection module.

[0013] As a further supplement to this application, the current database is used to store leakage current data, and the leakage test auxiliary system also includes a counting module, which is used to record the number of leakages detected by the leakage protection switch. When the number of leakages detected reaches n times within the set time, the automatic test module is started to test the leakage protection switch.

[0014] As a further supplement to the present application, the leakage protection switch includes a switch body and a gate body electrically connected to the switch body, and the outer end of the switch body is also electrically connected to a test button and a reset button.

DETAILED DESCRIPTION

[0037] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0038] The first implementation method:

[0039] The present invention provides an electrical control cabinet with anti-leakage function, please refer to Figure 1 and Figure 2 , including a cabinet 1 and a leakage test auxiliary system. A leakage protection switch 2 is fixedly connected to the inner wall of the cabinet 1. The input end of the leakage protection switch 2 is connected to the main power supply, and the output end of the leakage protection switch 2 is connected to a first transfer switch. The first transfer switch is connected to a second transfer switch and a test load. The second transfer switch is connected to a backup power supply and a power-consuming end. The power-consuming end includes electrical components installed inside the cabinet 1.

[0040] Combine Figure 5 As shown, the leakage protection switch 2 includes a switch body 21 and a gate body 22 electrically connected to the switch body 21. The outer end of the switch body 21 is also electrically connected to a test button 23 and a reset button 24. This is the basic structural setting of the leakage protection switch 2 in the prior art.

[0041] See also Figure 2 In the initial state, the leakage protection switch 2 transmits power to the first and second transfer switches through the first transfer switch, and the first transfer switch transmits power to the power end through the second transfer switch. The main power source is generally the distribution network, that is, under normal circumstances, the electrical components inside the cabinet 1 are powered by the distribution network. In the prior art, the test button 23 is mainly used to detect whether the protection function of the equipment or circuit is working properly, that is, to test the reliability of the leakage protection switch 2. Its principle is to verify whether the protection function is normal by simulating a leakage fault. After pressing the button, if the protector can trip quickly, it means that the leakage protection switch 2 is normal. If it cannot trip, there may be a fault and timely maintenance is required. Therefore, when the leakage protection switch 2 is not faulty, the gate body 22 will trip, disconnecting the main power source from the electrical components, causing the electrical components to stop operating due to power outage. Therefore, in actual practice, the reliability test of the leakage protection switch 2 is generally selected during the off-peak period of electricity consumption. However, this test process will still affect the continuous operation of the electrical components in the cabinet 1, causing temporary paralysis of the electrical components in the cabinet 1 and the associated external electrical equipment.

[0042] In view of the above practical problems, the present application realizes the following circuit switching operation by setting the test load, the first transfer switch, the second transfer switch and the backup power supply: When the reliability test of the leakage protection switch 2 is performed, as shown in FIG. Figure 3 As shown, the first transfer switch and the second transfer switch are automatically started, so that the leakage protection switch 2 transmits power to the test load through the first transfer switch, and the backup power supply transmits power to the power end through the second transfer switch; through the above operation, a loop is formed between the leakage protection switch 2 and the test load, so that the leakage protection switch 2 can perform reliability testing normally. The test load can be an ordinary electrical equipment (such as lighting equipment). At the same time, the electrical components are powered by the backup power supply, so that the test process of the leakage protection switch 2 is not likely to affect the operation of the electrical components and external related electrical equipment.

[0043] See also Figure 1 、 Figure 6 and Figure 7 A hardware auxiliary unit is provided inside the cabinet 1, and the hardware auxiliary unit includes a pair of two-axis slide rails 4 and a dynamic frame 5 installed between the pair of two-axis slide rails 4. The dynamic frame 5 includes a horizontal plate 51. The end of the horizontal plate 51 close to the leakage protection switch 2 is fixedly connected to a protruding plate 52. The upper end of the horizontal plate 51 is fixedly connected to a motor 53. The output end of the motor 53 is fixedly connected to a rotating shaft 54. The outer end of the rotating shaft 54 ​​is fixedly connected to a moving plate 55.

[0044] Combine Figure 8 As shown, the test button 23 and the reset button 24 are arranged in an upper and lower manner, and the gate body 22 and the test button 23 are arranged in a horizontal manner. The test button 23 corresponds to the position of the protruding plate 52. Through the movement of the two-axis slide rail 4, the horizontal plate 51 and the protruding plate 52 are driven to move, so that the protruding plate 52 presses the test button 23 or the reset button 24, replacing the manual operation of the personnel, and automatically realizing the reliability test process and the closing process of the leakage protection switch 2. The gate body 22 corresponds to the position of the movable plate 55. In the initial state, the movable plate 55 is vertically distributed on the rotating shaft 54, and in this state, the two side end edges of the movable plate 55 are between the two side end edges of the horizontal plate 51. During the up and down movement of the dynamic frame 5, the movable plate 55 does not contact the gate body 22, and it is not easy to destroy the closing state of the gate body 22. When the leakage protection switch 2 itself fails and cannot trip, it needs to use the dynamic frame 5. The motor 53 can be started to drive the movable plate 55 to rotate to the position shown in FIG. Figure 6 In the horizontal state shown, the distance between the movable plate 55 and the leakage protection switch 2 is much smaller than the distance between the protruding plate 52 and the leakage protection switch 2. When the protruding plate 52 is not in contact with the test button 23 and the reset button 24, the up and down movement of the movable plate 55 can assist in opening or closing the gate body 22.

[0045] See also Figure 4The leakage test auxiliary system includes a leakage protection module, a current database, an early warning module, an automatic test module, a judgment feedback module and a secondary protection module. The leakage protection switch 2 is connected to the leakage protection module, the two-axis slide 4, the first conversion switch and the second conversion switch are all connected to the automatic test module. The automatic test module is used to control the startup and operation of the above three. The motor 53 is connected to the secondary protection module. The secondary protection module is used to control the opening and closing of the motor 53. The leakage protection module is used to receive and record the leakage current changes monitored by the leakage protection switch 2, and control the early warning module to issue a leakage warning, and also send the leakage current data to the current database for storage. The leakage test auxiliary system also includes a counting module. The counting module is used to record the number of leakages detected by the leakage protection switch 2. When the number of leakages detected reaches n times within the set time (such as the number of leakages reaches 3 times within half an hour), the automatic test module is started to test the leakage protection switch 2.

[0046] The leakage protection switch 2 has the function of detecting, judging and actively cutting off the leakage current. When the leakage protection switch 2 detects that the leakage current exists and exceeds the set value (usually 30mA), the leakage protection switch 2 automatically cuts off. When the leakage current does not exceed the set value, the leakage protection switch 2 temporarily does not cut off, and the early warning module issues a first-level leakage warning.

[0047] In the prior art, the reliability test of the leakage protection switch 2 is generally performed monthly by manually pressing the test button 23. This method has the disadvantage of insufficient testing frequency, making it difficult to respond to sudden failures of the leakage protection switch 2 in a timely manner. If the manual operation is too frequent, a lot of manpower is consumed.

[0048] In response to the above problems, this application records the leakage current and its frequency. When the number of leakage detected reaches n times within the set time, it indicates that the leakage of the control cabinet is relatively frequent and there is a greater risk of leakage. At this time, in order to prevent the leakage protection switch 2 from failing to trip in the event of a large leakage, the automatic test module is started to automatically test the leakage protection switch 2 to detect the reliability of the leakage protection switch 2 and effectively ensure the timely response performance of the leakage protection switch 2.

[0049] See also Figure 6The two-axis slide rail 4 includes a horizontal guide rail 41 fixedly connected to the inner wall of the cabinet 1, and the outer end of the horizontal guide rail 41 is horizontally slidably connected to the horizontal slide seat 42. The end of the horizontal slide seat 42 close to the dynamic frame 5 is fixedly connected to the vertical guide rail 43. The outer end of the vertical guide rail 43 is vertically slidably connected to the vertical slide seat 44. The horizontal plate 51 is fixedly connected between the pair of vertical slide seats 44. The horizontal movement of the horizontal slide seat 42 on the horizontal guide rail 41 and the vertical sliding of the vertical slide seat 44 on the vertical guide rail 43 realize the corresponding position adjustment of the dynamic frame 5. The position adjustment process can be used for the automatic test operation, closing operation and auxiliary opening operation of the leakage protection switch 2;

[0050] When the automatic test module is started to test the leakage protection switch 2, the following steps are included:

[0051] like Figure 9 and Figure 10 As shown, the vertical slide 44 first moves vertically, driving the protruding plate 52 to move to the same level as the test button 23. Then, the horizontal slide 42 slides horizontally, driving the dynamic frame 5 to move closer to the test button 23, so that the protruding plate 52 presses the test button 23 instead of manually pressing it, so that the leakage protection switch 2 performs a reliability test (before performing this operation, the circuit switching operation described above is performed first, and the dynamic plate 55 is in a vertical state);

[0052] The judgment feedback module is used to determine whether there is a response fault in the leakage protection switch 2:

[0053] 1. After the above operation, if the leakage protection switch 2 is detected to be normal, the closing operation is performed: the dynamic frame 5 is moved again by the two-axis slide rail 4 so that the dynamic frame 5 presses the reset button 24 (as shown in FIG. Figure 11 ), then refer to Figure 12 , move the dynamic frame 5 in the direction away from the leakage protection switch 2, and then move it downward until the dynamic frame 5 is located at the lower side of the gate body 22, start the motor 53 to rotate the movable plate 55 to a horizontal state, and start the two-axis slide rail 4 again, first drive the dynamic frame 5 to move in the direction close to the leakage protection switch 2, so that the movable plate 55 is close to the side edge of the leakage protection switch 2 and is located directly under the gate body 22, then move the dynamic frame 5 upward, push the gate body 22, and close the gate body 22 in the tripped state. After closing, start the first transfer switch and the second transfer switch to restore the circuit to the state as shown in the figure. Figure 2 The initial state shown;

[0054] 2. Through the above operation, when it is detected that the leakage protection switch 2 cannot automatically trip under the condition of leakage, the early warning module will first issue a fault warning so that personnel can carry out maintenance in time, and then start the first transfer switch and the second transfer switch to restore the circuit to normal. Figure 2In the initial state shown, the leakage protection switch 2 continues to monitor leakage;

[0055] During the period before the personnel carry out maintenance, when the leakage current is detected to exceed the set value, the following auxiliary opening operation is performed through the two-axis slide rail 4 and the dynamic frame 5: Figure 13 and Figure 14 As shown, the dynamic frame 5 is moved in the direction away from the leakage protection switch 2, and then moved upward until it is located on the upper side of the gate body 22, the movable plate 55 is rotated to a horizontal state, and the two-axis slide rail 4 is started again, first driving the dynamic frame 5 to move in the direction close to the leakage protection switch 2, so that the movable plate 55 is close to the side edge of the leakage protection switch 2 and is located just above the gate body 22, and then the dynamic frame 5 is moved downward to push the gate body 22, and the gate body 22 in the closed state is opened to disconnect the circuit, that is, to disconnect the power supply to the electrical components in the cabinet 1, thereby reducing electric shock accidents caused by leakage of the cabinet 1. At the same time, the early warning module performs a secondary leakage early warning, so that the staff can repair the electrical control cabinet in time.

[0056] Second implementation method:

[0057] This implementation method adds the following contents based on the first implementation method: Figure 1 、 Figure 2 and Figure 4 The power-consuming end also includes a visual load 3 installed inside the cabinet 1. The visual load 3 includes an opaque box fixedly connected to the inner wall of the cabinet 1. The interior of the opaque box is fixedly connected with an LED lamp and a light sensor. The leakage test auxiliary system also includes a visual feedback module and a macro database. Both the LED lamp and the light sensor are connected to the visual feedback module. The light sensor is used to monitor the changes in the brightness data of the LED and transmit it to the visual feedback module. The visual feedback module is used to store the brightness data of the LED in the case of leakage in the macro database, and the brightness data in the macro database corresponds one to one to the leakage current data in the current database.

[0058] When it is detected that the leakage protection switch 2 cannot automatically trip under the condition of leakage, the above structure provides another triggering mechanism for the auxiliary tripping operation, as follows: Since the leakage protection switch 2 has a failure that cannot automatically trip, its detection of the leakage current is likely to be inaccurate. At this time, the data of the visual recording load 3 can further reflect the change of the leakage current, and the principle is as follows: In the early stage, when the leakage protection switch 2 is normal, the leakage current data will be stored in the current database. At the same time, due to the leakage of the circuit, part of the current will flow into the ground through the cabinet 1, causing the current of the electrical elements and the visual recording load 3 to change, thereby causing the brightness of the visual recording load 3 to change, the monitoring data of the light sensor to change, and the data to be stored in the macro database. The data corresponds to the leakage current data monitored by the leakage protection switch 2 at the same time. Let the leakage current data in the current database be I1, I2, I3...In, and In be the set value for triggering the automatic tripping of the leakage protection switch 2. The brightness data in the macro database is Q1 (corresponding to I1), Q2 (corresponding to I2), Q3 (corresponding to I3)...Qn (corresponding to In). Therefore, during the period when the leakage protection switch 2 cannot automatically trip, when it monitors that the leakage current reaches In, or when the light sensor monitoring data reaches Qn, the auxiliary tripping operation will be triggered, achieving that when the leakage protection switch 2 leakage current monitoring is inaccurate, the data change of the visual recording load 3 can also trigger the auxiliary tripping operation, effectively reducing the electric shock accidents of personnel.

[0059] In combination with the current actual needs, the above-mentioned embodiments adopted by the present application are not limited to this, various changes within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
