Description

[0001] The present application relates to the technical field of electric meter detection, in particular to a power plant electric energy meter detection device. BACKGROUND

[0002] With the continuous development of the power industry, the accuracy and compliance of the guide rail type electric energy meter as an important equipment in the field of electric power measurement are of great significance to the fair trade of the power market. In the production process of the guide rail type electric energy meter, the compliance detection of the signal interface is a key step to ensure the stable performance and accurate measurement of the electric meter.

[0003] Traditional guide rail type electric energy meter detection usually relies on automated detection equipment. These devices can efficiently and accurately complete the test of various performance indicators of the electric meter through pre-set test procedures. However, in actual production lines, automated detection equipment may occasionally malfunction or require maintenance, which requires manual intervention for detection to ensure continuous operation of the production line.

[0004] In manual detection of guide rail type electric energy meters, a major challenge is the high voltage of the electric meter zero line and fire line interface. Since the voltage connected by these interfaces is usually large, during the detection process, it is generally necessary to first cut off the power, wait for the voltage on the electric meter zero line and fire line interface to drop to a safe range, then perform the plugging operation, complete the plugging operation, and then re-energize for detection. In order to prevent the risk of electric shock to the worker, after the detection is completed, it also needs to be de-energized. This operation process, although it ensures the safety of the detection process, undoubtedly increases the detection time and reduces the detection efficiency. In order to solve the above problems, we propose a power plant electric energy meter detection device. SUMMARY

DETAILED DESCRIPTION

[0025] In order to make the above objectives, features and advantages of the present application more clear and comprehensible, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details given herein, that the present application can be practiced with other different ways, and that the present application is not limited to the embodiments disclosed below.

[0027] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0028] Embodiment 1, with reference to FIG. 1 to FIG. 2, is the first embodiment of the present application, which provides a power plant electric energy meter detection device, which can realize the detection of the test of the electric energy meter through the plug-in to achieve the effect of power on, and the effect of power off by pulling out, and saves the trouble of manual switch power supply. The device comprises a detection mechanism 100, which comprises a detector 101, a power line 102 arranged on the detector 101, and a test line 103 arranged on the detector 101. The detector 101 is an oscilloscope, the power line 102 supplies power to the oscilloscope, and the test line 103 is used to connect the signal interface on the electric energy meter. The oscilloscope detects whether the signal interface of the electric energy meter is normal. The electric energy meter power-on mechanism 200 comprises an electric connection assembly 201 arranged on the detector 101, and a plug-in assembly 202 arranged on the electric connection assembly 201. The electric connection assembly 201 is used to connect the electric connection interface of the electric energy meter to supply power to the electric energy meter, so that the electric energy meter operates normally. Then the signal of the electric energy meter is transmitted to the oscilloscope through the test line 103. If the signal can be normally transmitted, it means that the interface is normal,

[0029] The plug-in assembly 202 comprises a first plug-in part 202a arranged on the electric connection assembly 201, a resilient part 202b arranged on the first plug-in part 202a, and a second plug-in part 202c arranged on the end of the first plug-in part 202a away from the electric connection assembly 201. The second plug-in part 202c is electrically connected to the first plug-in part 202a through the resilient part 202b.

[0030] The first plug-in part 202a is electrically connected with the power connection assembly 201, the elastic part 202b is rotationally connected with the first plug-in part 202a, the second plug-in part 202c and the elastic part 202b are both made of copper, the first plug-in part 202a is fixedly connected with the second plug-in part 202c, but the electrically connecting parts of the first plug-in part 202a and the second plug-in part 202c do not contact each other, the first plug-in part 202a and the second plug-in part 202c are connected together to form a plug-in rod, which is used to plug into the power supply port of the electric energy meter, i.e. the live wire interface and the neutral wire interface, and the elastic part 202b protrudes from the outer wall of the plug-in rod in the initial state, so that when the plug-in rod formed by the first plug-in part 202a and the second plug-in part 202c is plugged into the interface, the inner wall of the interface will press the protruding elastic part 202b inward, so that the elastic part 202b is rotated to be connected with the electrically connecting parts of the first plug-in part 202a and the second plug-in part 202c, thereby the first plug-in part 202a and the second plug-in part 202c are electrically connected, and the second plug-in part 202c plugged into the power supply interface of the electric meter supplies power to the electric meter, at this time, the test wire 103 can be used to connect the signal port of the electric meter to detect the port of the electric energy meter.

[0031] After the detection is completed, the plug-in assembly 202 is pulled out of the power supply interface of the electric meter, the elastic part 202b is reset, and the electrical connection between the first plug-in part 202a and the second plug-in part 202c is disconnected, wherein the electrically connecting part of the first plug-in part 202a is located at the center of the first plug-in part 202a, and the outer wall of the first plug-in part 202a is made of insulating material, so that after the electrical connection between the first plug-in part 202a and the second plug-in part 202c is disconnected, the second plug-in part 202c exposed to the outside is not electrified, thereby avoiding the situation that the operator is mistakenly electrified during the operation.

[0032] The power connection assembly 201 includes the live wire connection 201a and the neutral wire connection 201b arranged on the detector 101, and the live wire connection 201a and the neutral wire connection 201b are electrically connected with the power supply line 102, and the power supply of the live wire connection 201a and the neutral wire connection 201b comes from the power connection of the power supply line 102.

[0033] Through the arrangement of the elastic part 202b, the plug-in assembly 202 can be electrified when plugging in and can be de-energized after being pulled out, thereby avoiding the danger of being electrified by manual operation, and at the same time, after the plug-in assembly 202 is plugged in, the elastic part 202b is clamped by the elastic force, thereby improving the stability of the plugging, avoiding the trouble of manual locking, and improving the efficiency of manual detection.

[0034] Embodiment 2, referring to FIG. 1 to FIG. 5, is a second embodiment of the present application, which is different from the previous embodiment in that the first plug-in component 202a comprises an electrically connecting column 202a-1 electrically connected with the electrically connecting assembly 201, a handheld tube 202a-2 sleeved on the electrically connecting column 202a-1, and a protective sleeve 202a-3 arranged at an end of the handheld tube 202a-2 away from the electrically connecting assembly 201, and the elastic members 202b are arranged in an annular array on the circumferential sidewall of the protective sleeve 202a-3.

[0035] In this embodiment, the electrically connecting column 202a-1 is electrically connected with the electrically connecting assembly 201, the electrically connecting column 202a-1 is a copper column, and a stopper is welded on the circumferential sidewall of the copper column, the handheld tube 202a-2 wraps the stopper and the copper column close to the electrically connecting assembly 201, and the protective sleeve 202a-3 is welded at one end of the handheld tube 202a-2, and both the handheld tube 202a-2 and the protective sleeve 202a-3 are made of hard insulating material, which avoids electric shock of the operator and makes it easier for the operator to insert the plug-in assembly 202 into the interface of the electric energy meter.

[0036] The handheld tube 202a-2 has a T-shaped cross section, and the “one” end of the T-shaped handheld tube 202a-2 can be in contact with the interface when the plug-in assembly 202 is inserted into the interface of the electric energy meter, thereby reminding the operator that the plug-in assembly 202 has been inserted in place, and avoiding the situation that the plug-in assembly 202 is not inserted in place due to careless insertion of the operator.

[0037] The elastic members 202b are arranged in an annular array on the circumferential sidewall of the protective sleeve 202a-3, and the multiple elastic members 202b are deformed by rotation and extrude the inner wall of the interface, so that the plug-in assembly 202 and the interface have a large friction, which improves the insertion stability of the plug-in assembly 202, thereby improving the electrically connecting performance and avoiding poor contact.

[0038] The circumferential sidewall of the protective sleeve 202a-3 is annularly arrayed with a movable groove 202a-4, which is L-shaped, a rotating shaft 202a-5 is arranged in the movable groove 202a-4, and the elastic members 202b are rotatably installed in the movable groove 202a-4 through the rotating shaft 202a-5, and the circumferential sidewall of the protective sleeve 202a-3 is annularly arrayed with a strip-shaped groove 202a-6, which is correspondingly matched with the elastic members 202b.

[0039] In this embodiment, the movable groove 202a-4 is L-shaped, one segment of the L-shaped groove penetrates the circumferential side wall of the protective sleeve 202a-3, and the rotating shaft 202a-5 is fixedly installed in the area where the movable groove 202a-4 penetrates the circumferential side wall of the protective sleeve 202a-3, the elastic member 202b is rotatably sleeved on the rotating shaft 202a-5, one end of the power connection column 202a-1 extends into the inner cavity of the protective sleeve 202a-3, and the end head is located below the rotating shaft 202a-5, and one segment of the protrusion on the elastic member 202b extends into the inside of the protective sleeve 202a-3 through the penetrating movable groove 202a-4, and the initial state is inclined, and the power connection column 202a-1 is not in contact, and the tail end of the elastic member 202b extends to the outside of the protective sleeve 202a-3 and is bent into the strip-shaped groove 202a-6.

[0040] The elastic member 202b includes a spring 202b-1 rotatably installed on the rotating shaft 202a-5, the spring 202b-1 is provided with a first power connection segment 202b-2, an elastic segment 202b-3, a clamping segment 202b-4 and a second power connection segment 202b-5, and the second power connection segment 202b-5 is provided with a connecting end head 202b-6.

[0041] In this embodiment, the elastic member 202b is a special-shaped spring 202b-1 wound by a copper wire, as shown in FIG. 5, when the plug-in assembly 202 is plugged into the electric meter interface, the inner wall of the interface pushes the second power connection segment 202b-5 and the clamping segment 202b-4, so that the spring 202b-1 rotates, so that the first power connection segment 202b-2 rotates and is attached to the power connection column 202a-1 to realize power supply, and the second power connection segment 202b-5 is attached and extruded to the second plug-in member 202c during rotation, so as to realize power supply to the electric meter by the second plug-in member 202c inserted into the electric meter.

[0042] The connecting end head 202b-6 is used for welding the two ends of the special-shaped spring 202b-1 wound by the copper wire, and the connecting end head 202b-6 is smooth in circumference, so that when the second power connection segment 202b-5 is extruded and attached to the second plug-in member 202c, the bifurcation of the copper wire end head is avoided, which causes poor contact, and at the same time, the smooth side wall of the connecting end head 202b-6 extruded and attached to the second plug-in member 202c enables the plug-in assembly 202 to be more smoothly plugged in.

[0043] The first power connection segment 202b-2 is a protruding V-shaped segment of the spring 202b-1 during winding, and the protruding V-shaped segment of the first power connection segment 202b-2 extends to the inner cavity of the protective sleeve 202a-3 through the movable groove 202a-4, and the first power connection segment 202b-2 is electrically connected with the end head of the power connection column 202a-1 by rotating the rotating shaft 202a-5.

[0044] In this embodiment, the first power contact section 202b-2 enters the protective sleeve 202a-3 through the through active slot 202a-4. In the initial state, there is a certain gap between the first power contact section 202b-2 and the power contact column 202a-1, so that the elastic member 202b is not electrified before the plug-in assembly 202 is inserted into the electric meter interface, thereby avoiding that the clamping section 202b-4 protruding from the outer wall of the protective sleeve 202a-3 is electrified and injures people, and the electrified power contact column 202a-1 is located inside the protective sleeve 202a-3, so that the operator will not be electrocuted even if he is mistakenly touched.

[0045] The active slot 202a-4 is provided with a contact surface 202a-8, and the elastic section 202b-3 is a protruding V-shaped section when the spring 202b-1 is wound, and the elastic section 202b-3 is attached to the contact surface 202a-8.

[0046] In this embodiment, the elastic section 202b-3 is in a horizontal state in the initial state, attached to the contact surface 202a-8, and at this time the first power contact section 202b-2 is in contact with the lower end of the active slot 202a-4, thereby avoiding that the elastic member 202b is randomly rotated along the rotating shaft 202a-5, causing the second power contact section 202b-5 to be separated from the strip-shaped slot 202a-6.

[0047] If the first power contact section 202b-2 does not contact the lower end of the active slot 202a-4 and can be randomly rotated without limit in the active slot 202a-4, then when the plug-in assembly 202 is inserted into the electric meter interface, part of the elastic members 202b in the annular array will be pulled down by gravity, causing the second power contact section 202b-5 to be separated from the strip-shaped slot 202a-6, so that when the plug-in assembly 202 is inserted, the interface will not rotate the elastic member 202b into the inner cavity of the protective sleeve 202a-3, but will push the elastic member 202b outward, which will cause the elastic member 202b to be unable to enter the interface and hinder the insertion of the plug-in assembly 202.

[0048] After the plug-in assembly 202 is inserted into the electric meter interface, the rotation of the spring 202b-1 will cause the elastic section 202b-3 and the contact surface 202a-8 to be extruded and deformed, so that after the plug-in assembly 202 is pulled out, the elastic member 202b can be reset.

[0049] The clamping section 202b-4 extends to the outside of the protective sleeve 202a-3 through the active slot 202a-4, and the clamping section 202b-4 and the protective sleeve 202a-3 are inclined in the length direction, the second power contact section 202b-5 is the tail end of the spring 202b-1, and the second power contact section 202b-5 extends to the inside of the strip-shaped slot 202a-6 and does not enter the inner cavity of the protective sleeve 202a-3.

[0050] In this embodiment, the card joint section 202b-4 and the protective sleeve 202a-3 are obliquely arranged in the length direction, so that after the plug-in assembly 202 is plugged into the electric energy meter interface, the spring 202b-1 is rotated to make the card joint section 202b-4 flush with the inner wall of the interface, thereby increasing the contact area and preventing the plug-in assembly 202 from falling off.

[0051] After the second power connection section 202b-5 enters the strip-shaped slot 202a-6, the included angle between the second power connection section 202b-5 and the outer wall of the protective sleeve 202a-3 close to one end of the second plug-in part 202c is greater than 145 degrees, thereby facilitating the interface to push the second power connection section 202b-5 during plugging, so that the spring 202b-1 is rotated, and when the card joint section 202b-4 is flush with the inner wall of the electric meter interface, the second power connection section 202b-5 is in contact with the second plug-in part 202c.

[0052] The end of the protective sleeve 202a-3 away from the power connection assembly 201 is provided with a threaded head 202a-7, and the second plug-in part 202c includes a power connection sleeve 202c-1 threadedly connected with the threaded head 202a-7, and the power connection sleeve 202c-1 is internally provided with a conductive column 202c-2.

[0053] In this embodiment, the power connection sleeve 202c-1 and the conductive column 202c-2 are both made of copper, the power connection sleeve 202c-1 and the conductive column 202c-2 are integrally formed, the power connection sleeve 202c-1 is internally provided with a thread, the conductive column 202c-2 is arranged at the center of the power connection sleeve 202c-1, and when the power connection sleeve 202c-1 is threadedly connected with the threaded head 202a-7, the conductive column 202c-2 is inserted into the inner cavity of the protective sleeve 202a-3 and located below the second power connection section 202b-5, and when the second power connection section 202b-5 is rotated with the spring 202b-1, the second power connection section 202b-5 is in contact with the conductive column 202c-2, thereby enabling the power connection sleeve 202c-1 to be powered and supply power to the electric meter.

[0054] The remaining structures are the same as those of Embodiment 1.

[0055] Embodiment 3, referring to FIGS. 1-6, is a third embodiment of the present application, which is different from the previous embodiment in that the embodiment provides a shaped sleeve 300, which solves the problem that the card joint section 202b-4 is bent and deformed when being pressed, thereby failing to drive the spring 202b-1 to rotate, and thereby causing unstable electrical connection between the first power connection section 202b-2 and the power connection column 202a-1, and the shaped sleeve 300 includes a card joint section 202b-4 externally sleeved with the shaped sleeve 300, one end of the shaped sleeve 300 is provided with a contact block 301, and one end of the shaped sleeve 300 is provided with a guide surface 302.

[0056] In the embodiment, the shaped sleeve 300 is sleeved at the position of the clamping section 202b-4 to the spring 202b-1, the abutting block 301 is arranged in an arc shape and is integrally formed at the position of the shaped sleeve 300 close to the rotating shaft 202a-5, the end of the abutting block 301 away from the shaped sleeve 300 abuts the transition position between the elastic section 202b-3 and the spring 202b-1, and the shaped sleeve 300 is made of an insulating hard material, and the transition is facilitated by the arrangement of the guide surface 302 during the plug-in process of the plug-in assembly 202 to the meter interface.

[0057] It should be noted that the end of the elastic section 202b-3 abuts the side wall of the movable groove 202a-4, so that when the abutting block 301 abuts the transition position between the elastic section 202b-3 and the spring 202b-1, the abutting block 301 is prevented from being inserted into the gap between the spring 202b-1 and the rotating shaft 202a-5.

[0058] Meanwhile, the shaped sleeve 300 plays a role of insulation protection, and because the elastic section 202b-3 is V-shapedly bent in two sections and the clamping section 202b-4 is made of two ends of a copper wire, the clamping section 202b-4 is more likely to deform when being pressed during the plug-in process, and the spring 202b-1 cannot be rotated, so that the electrical connection between the first plug-in assembly 202a and the second plug-in assembly 202c cannot be achieved. However, because the shaped sleeve 300 is arranged, the clamping section 202b-4 cannot pass through the shaped sleeve 300 and the abutting block 301 cannot deform during the plug-in process, so that the clamping section 202b-4 and the spring 202b-1 cannot be deformed, the elastic section 202b-3 and the abutting surface 202a-8 are pressed and deformed, the second electrical connection section 202b-5 and the conductive column 202c-2 are attached, the first electrical connection section 202b-2 and the electrical connection column 202a-1 are attached, so that the electrical connection between the first plug-in assembly 202a and the second plug-in assembly 202c is achieved.

[0059] The remaining structures are the same as those in Embodiment 2.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application, and although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
