Description

Technical Field

[0001] The invention relates to the technical field of electric meter detection, in particular to an electric energy meter detection device for a thermal power plant. Background Art

[0002] With the continuous development of the power industry, rail-type watt-hour meters, as important equipment in the field of power measurement, are of great significance to fair transactions in the power market in terms of accuracy and compliance. In the production process of rail-type watt-hour meters, compliance testing of the signal interface is a key step to ensure stable performance and accurate measurement of the meter.

[0003] Traditional rail-type electricity meter testing usually relies on automated testing equipment. These devices can efficiently and accurately complete the testing of various performance indicators of the meter through preset test procedures. However, on the actual production line, the automated testing equipment occasionally fails or requires maintenance. At this time, manual intervention is required to ensure the continuous operation of the production line.

[0004] When manually inspecting rail-type electric energy meters, a major challenge is the high voltage at the zero-wire and live-wire interfaces of the electric energy meter. Since the voltages connected to these interfaces are usually large, it is generally necessary to first cut off the power during the inspection process, and then perform the plugging operation after the voltage on the zero-wire and live-wire interfaces of the electric energy meter drops to a safe range. After the plugging is completed, the power is turned on again for inspection. In order to prevent the risk of electric shock to the staff, the power needs to be cut off after the inspection is completed. Although this operation process ensures the safety of the inspection process, it undoubtedly increases the inspection time and reduces the inspection efficiency. In order to solve the above problems, we propose a thermal power plant electric energy meter inspection device. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figure 1 to Figure 2, is the first embodiment of the present invention, which provides an electric energy meter detection device for a thermal power plant, which can realize the test of the electric energy meter by plugging in the detection equipment, and can achieve the effect of power off by unplugging, thereby eliminating the trouble of manually switching the power supply. The detection device includes a detection mechanism 100, which includes a detector 101, and also includes 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, and the power line 102 supplies power to the oscilloscope. At the same time, the test line 103 is used to connect the signal interface on the electric energy meter, and the oscilloscope is used to detect whether the signal interface of the electric energy meter is normal. The electric meter power-on mechanism 200 includes a power connection component 201 arranged on the detector 101, and a plug-in component 202 arranged on the power connection component 201. The power connection component 201 is used to connect the power connection interface of the electric energy meter to supply power to the electric energy meter, so that the electric energy meter can operate normally, and then the signal of the electric energy meter is transmitted to the oscilloscope through the test line 103. If the signal can be transmitted normally, it means that the interface is normal.

[0030] The plug assembly 202 includes a first plug 202a disposed on the power connection assembly 201, an elastic member 202b disposed on the first plug 202a, and a second plug 202c disposed at an end of the first plug 202a away from the power connection assembly 201, and the second plug 202c is electrically connected to the first plug 202a through the elastic member 202b.

[0031] The first connector 202a is electrically connected to one end of the power connection component 201, the elastic member 202b is rotatably connected to the first connector 202a, the second connector 202c and the elastic member 202b are both made of copper, the first connector 202a and the second connector 202c are fixedly connected, but the power connection parts therebetween are not in contact, the first connector 202a and the second connector 202c are connected together to form a plug rod for plugging into the power supply port of the energy meter, that is, the live wire interface and the neutral wire interface, and the elastic member 202b has a section protruding from the plug rod in the initial state. The outer wall, therefore, after the plug-in rod formed by the first connector 202a and the second connector 202c is inserted into the interface, the inner wall of the interface squeezes the protruding elastic member 202b inward, so that the elastic member 202b rotates and connects with the power connection parts of the first connector 202a and the second connector 202c, thereby making the first connector 202a and the second connector 202c electrically connected, and the second connector 202c plugged into the power-on interface of the electric meter supplies power to the electric meter. At this time, the test line 103 can be used to connect the signal port of the electric meter to detect the electric energy meter port.

[0032] After the detection is completed, the plug-in component 202 is unplugged from the power interface of the electric meter, the elastic member 202b is reset, and the electrical connection between the first connector 202a and the second connector 202c is disconnected, wherein the power connection portion of the first connector 202a is located at its axis, and the outer wall of the first connector 202a is made of insulating material. Therefore, after the electrical connection between the first connector 202a and the second connector 202c is disconnected, the exposed second connector 202c is not electrified, thereby avoiding the occurrence of accidental electric shock during operation.

[0033] The power connection component 201 includes a live wire connection 201a and a neutral wire connection 201b arranged on the detector 101 , and the live wire connection 201a and the neutral wire connection 201b are electrically connected to the power line 102 , and the power of the live wire connection 201a and the neutral wire connection 201b comes from the power connection of the power line 102 .

[0034] Example 2, reference Figures 1 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, the first connector 202a includes a power connection post 202a-1 electrically connected to the power connection component 201, and also includes a hand-held tube 202a-2 sleeved on the power connection post 202a-1, and a protective sleeve 202a-3 arranged at the end of the hand-held tube 202a-2 away from the power connection component 201, and the elastic member 202b is arranged in a ring array on the circumferential side wall of the protective sleeve 202a-3.

[0035] In this embodiment, the power connection post 202a-1 and the power connection component 201 are electrically connected. The power connection post 202a-1 is a copper column, and a block is welded on the circumferential side wall of the copper column. The hand-held tube 202a-2 wraps the block and the copper column on the side of the block close to the power connection component 201. A protective cover 202a-3 is welded at one end of the hand-held tube 202a-2, and the hand-held tube 202a-2 and the protective cover 202a-3 are both made of hard insulating materials to prevent the operator from electric shock. At the same time, the hard material makes it easier for the operator to insert the plug-in component 202 into the interface of the electric energy meter.

[0036] The cross-sectional view of the hand-held tube 202a-2 is T-shaped. When the plug-in component 202 is inserted into the interface of the electric energy meter, the "I"-shaped end of the T-shaped hand-held tube 202a-2 can interfere with the interface, thereby reminding the operator that it has been plugged in place, avoiding the situation where the staff plugs in carelessly and causes improper plugging.

[0037] Furthermore, a ring array of elastic members 202b is arranged on the circumferential side wall of the protective sleeve 202a-3. Through the rotation and deformation of multiple elastic members 202b, the inner wall of the interface is squeezed, so that the plug-in component 202 and the interface have greater friction, thereby improving the plug-in stability of the plug-in component 202, thereby improving the electrical connection performance and avoiding poor contact.

[0038] A movable groove 202a-4 is provided in a circular array on the circumferential side wall of the protective sleeve 202a-3, and the movable groove 202a-4 is provided in an L-shape. A rotating shaft 202a-5 is provided in the movable groove 202a-4, and the elastic member 202b is rotatably installed in the movable groove 202a-4 through the rotating shaft 202a-5. A strip groove 202a-6 is provided in a circular array on the circumferential side wall of the protective sleeve 202a-3, and the strip groove 202a-6 and the elastic member 202b correspond to each other.

[0039] In this embodiment, the movable groove 202a-4 is opened in an L shape, and one section of the L shape passes through 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 passes through the circumferential side wall of the protective sleeve 202a-3, and the elastic member 202b is rotatably sleeved on the rotating shaft 202a-5, one end of the power pole 202a-1 extends into the inner cavity of the protective sleeve 202a-3, and the end is located below the rotating shaft 202a-5, and a section of the protrusion on the elastic member 202b extends into the interior of the protective sleeve 202a-3 through the penetrating movable groove 202a-4. In its initial state, it is tilted and does not contact the power pole 202a-1. The tail end of the elastic member 202b extends to the outside of the protective sleeve 202a-3 and bends into the strip groove 202a-6.

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

[0041] In this embodiment, the elastic member 202b is formed by winding a copper wire into a special-shaped spring 202b-1, such as Figure 5 As shown, when the plug-in component 202 is plugged into the interface of the electric meter, the inner wall of the interface pushes the second power connection section 202b-5 and the clamping section 202b-4, causing the spring 202b-1 to rotate, thereby causing the first power connection section 202b-2 to rotate and fit the power connection post 202a-1 to achieve power supply, and the second power connection section 202b-5 will fit and squeeze the second connector 202c when rotating, thereby realizing the second connector 202c inserted into the electric meter to power the electric meter.

[0042] Furthermore, the connecting end 202b-6 is used to weld the two ends of the special-shaped spring 202b-1 wrapped with copper wire, and the connecting end 202b-6 is rounded, so that when the second power connection section 202b-5 is squeezed and fitted with the second connector 202c, the copper wire end is prevented from bifurcating and causing poor contact. At the same time, the connecting end 202b-6 is squeezed and fitted with the second connector 202c through the smooth side wall, which also allows the connector assembly 202 to be plugged in more smoothly.

[0043] The first power connection section 202b-2 is a protruding V-shaped section when the spring 202b-1 is wound, and the protruding V-shaped section of the first power connection section 202b-2 passes through the movable groove 202a-4 and extends into the inner cavity of the protective sleeve 202a-3. The first power connection section 202b-2 rotates around the rotating shaft 202a-5 and is electrically connected to the end of the power connection post 202a-1.

[0044] In this embodiment, the first power connection section 202b-2 enters the interior of the protective sleeve 202a-3 through the penetrating movable groove 202a-4. In the initial state, there is a certain gap between the first power connection section 202b-2 and the power connection post 202a-1, so that the elastic member 202b is not charged before the plug-in assembly 202 is not inserted into the meter interface, thereby avoiding the clamping section 202b-4 protruding from the outer wall of the protective sleeve 202a-3 from being charged and injuring people, and the charged power connection post 202a-1 is located inside the protective sleeve 202a-3, and the operator will not be electrocuted even if it touches it by mistake.

[0045] The movable groove 202a-4 is provided with a contact surface 202a-8, the elastic section 202b-3 is a protruding V-shaped section when the spring 202b-1 is wound, and the elastic section 202b-3 and the contact surface 202a-8 are in contact with each other.

[0046] In this embodiment, the elastic section 202b-3 is in a horizontal state in the initial state and fits against the abutment surface 202a-8, and at this time, the first power-connecting section 202b-2 abuts against the lower end of the movable groove 202a-4, thereby preventing the elastic member 202b from rotating freely along the rotating shaft 202a-5, causing the second power-connecting section 202b-5 to be separated from the strip groove 202a-6.

[0047] If the first power connection section 202b-2 does not interfere with the lower port of the movable groove 202a-4 and can be rotated freely in the movable groove 202a-4 without limit, then when the plug-in component 202 is plugged into the interface of the electric energy meter, some of the elastic members 202b in the annular array fall down due to gravity, causing the second power connection section 202b-5 to disengage from the strip groove 202a-6, so that when plugged in, the interface will not push the elastic member 202b to rotate toward the inner cavity of the protective sleeve 202a-3, but push the elastic member 202b outward, which will prevent the elastic member 202b from entering the interface and hinder the plug-in of the plug-in component 202.

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

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

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

[0051] After the second power connection section 202b-5 enters the strip groove 202a-6, the angle between it and the outer wall of the end of the protective sleeve 202a-3 close to the second plug-in component 202c is greater than 145 degrees, so that when plugging in, the interface pushes the second power connection section 202b-5 to rotate the spring 202b-1. When the clamping section 202b-4 is flush with the inner wall of the meter interface, the second power connection section 202b-5 is deformed and fits the second plug-in component 202c.

[0052] A threaded head 202a-7 is disposed at one end of the protective sleeve 202a-3 away from the power connection component 201. The second connector 202c includes a power connection sleeve 202c-1 threadedly connected to the threaded head 202a-7, and a conductive column 202c-2 is disposed inside the power connection sleeve 202c-1.

[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, and a thread is provided inside the power connection sleeve 202c-1. The conductive column 202c-2 is arranged at the axis of the power connection sleeve 202c-1. When the power connection sleeve 202c-1 and the threaded head 202a-7 are threadedly connected, the conductive column 202c-2 is inserted into the inner cavity of the protective sleeve 202a-3 and is located below the second power connection section 202b-5. When the second power connection section 202b-5 rotates with the spring 202b-1, it contacts the conductive column 202c-2, so that the power connection sleeve 202c-1 can be energized and supply power to the electric meter.

[0054] The rest of the structure is the same as that of Example 1.

[0055] Example 3, reference Figures 1 to 6 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a shaping sleeve 300, which solves the problem that the clamping section 202b-4 bends and deforms when squeezed and cannot drive the spring 202b-1 to rotate, thereby causing the electrical connection between the first power connection section 202b-2 and the power connection pole 202a-1 to be unstable. It includes a shaping sleeve 300 sleeved on the outside of the clamping section 202b-4, and a resistance block 301 is provided at one end of the shaping sleeve 300, and a guide surface 302 is opened at one end of the shaping sleeve 300.

[0056] In this embodiment, the shaping sleeve 300 is sleeved at the position from the clamping section 202b-4 to the spring 202b-1, the abutment block 301 is arranged in an arc shape, and is integrally formed at the position of the shaping sleeve 300 close to the rotating shaft 202a-5, and the end of the abutment block 301 away from the shaping sleeve 300 abuts against the transition portion between the elastic section 202b-3 and the spring 202b-1, and the shaping sleeve 300 is made of an insulating hard material, and the setting of the guide surface 302 facilitates the transition during the process of plugging the plug-in component 202 into the meter interface.

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

[0058] At the same time, the shaping sleeve 300 plays the role of insulation protection. In addition, because the elastic section 202b-3 is a V-shaped bend of two sections, and the clamping section 202b-4 is the two ends of the copper wire, when it is squeezed during insertion, the clamping section 202b-4 is more likely to deform and cannot drive the spring 202b-1 to rotate. If this happens, the first plug-in component 202a and the second plug-in component 202c cannot be electrically connected. Because the shaping sleeve 300 makes the plug-in When connected, the clamping section 202b-4 cannot pass through the shaping sleeve 300 and the resistance block 301 cannot be deformed, so that the clamping section 202b-4 and the spring 202b-1 rotate without deformation, while the elastic section 202b-3 and the resistance surface 202a-8 are squeezed and deformed, the second power connection section 202b-5 and the conductive column 202c-2 are fitted, and the first power connection section 202b-2 and the power connection column 202a-1 are fitted, thereby realizing the electrical connection between the first connector 202a and the second connector 202c.

[0059] The rest of the structure is the same as that of Example 2.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
