Description

Technical Field

[0001] The present invention belongs to the field of electric energy meters, and relates to an electric energy meter wiring fixing clip device and a using method thereof. Background Art

[0002] Currently, in daily metering maintenance and engineering project work, there is a large amount of work that requires replacing electric energy meters. The current method is to first make marks in the arrangement order of the connecting wires of the electric energy meter, then remove the connecting wires, and then replace the electric energy meter. This method not only wastes time but also easily causes wiring errors of the electric energy meter due to the negligence of the staff in getting the wire arrangement order wrong. When replacing the electric energy meter, since only the electric energy meter of a single faulty user on the line is replaced, power-off processing generally cannot be performed, so live working is required. And because there is a section of bare copper wire in the core wire of the electric wire, in this case, it is extremely easy to cause the danger of electric shock.

[0003] In the existing wiring scheme, it is very difficult to fix the bare copper wires of the voltage and current wires clamped by the electric energy meter wiring fixing clip in the front, back, left, and right directions. It is extremely easy for them to come into contact with each other and discharge or come into contact with the surrounding metal parts and cause discharge, unable to form electromagnetic shielding, and there is a hidden danger of electric shock. Specifically, since it is difficult to fix the bare copper wires of the wires in the front, back, left, and right directions, this may cause the wires to move inside the clamping plate, increasing the risk of mutual contact between the wires. If the bare copper wires come into contact with each other or come into contact with the surrounding metal parts, a discharge phenomenon may occur, which will not only affect the normal operation of the equipment but also may cause safety accidents. At the same time, due to the ineffective fixing of the wires, the electromagnetic shielding effect may be poor, thereby affecting the electromagnetic compatibility of the equipment and the stability of signal transmission. If the bare copper wires come into contact with the operator, it may cause an electric shock accident, posing a threat to the safety of the operator.

[0004] As Figure 1 shown, it is an electric energy meter wiring fixing clip for replacing an electric energy meter with power on in the prior art. Its specific operation method is: open the clamping plate of the electric energy meter wiring fixing clip, then place the live wires in the wire grooves respectively, and lock the bare copper wires into the halved wire grooves. Due to the clamping effect of the wire grooves on the wires and the independence of the wire grooves from each other, it avoids the short circuit caused by the mutual contact of the wires and also avoids the situation where the bare wires come into contact with the electric energy meter box and cause electric shock to the staff. However, because Figure 1 the fixture in Summary of the Invention

[0005] The object of the present invention is to overcome the deficiencies of the prior art. To solve the metering faults caused by incorrect wiring at the tail of the metering device during the live replacement of the electricity meter and the electric shock problem of the operator accidentally touching the live position of the metering device, a wiring fixing clip device for an electricity meter with a safety protection function based on the user-side metering device and its usage method are proposed. Specifically, for high-voltage users, there are two metering methods: high-voltage supply with high metering and high-voltage supply with low metering. These two metering methods respectively correspond to the use of three-phase three-wire electricity meters and three-phase four-wire electricity meters. Therefore, the device needs to adapt to the wiring methods of various electricity meters, improve the replacement efficiency of the electricity meter, avoid incorrect wiring, reduce the incidence of metering faults, and reduce the occurrence of electric shock hazards.

[0006] In view of the wiring characteristics of the user-side metering device, the present invention analyzes the wiring topology relationship of the voltage and current wiring circuits, designs a wiring fixing clip device for an electricity meter, and proposes a usage method for the wiring fixing clip device of the user-side metering device that can improve the replacement efficiency of the electricity meter, avoid incorrect wiring, reduce the incidence of metering faults, and reduce the occurrence of electric shock hazards. On the basis of improving the replacement efficiency of the electricity meter, incorrect wiring is avoided, the incidence of metering faults is reduced, and the occurrence of electric shock hazards is reduced.

[0007] The technical solution adopted by the present invention to solve the technical problem is:

[0008] The first aspect of the present invention provides a wiring fixing clip device for an electricity meter, including: a fixing clip housing, a moving clip moving control mechanism. The fixing clip housing includes a fixed clip plate and a moving clip plate. One end of the fixed clip plate is provided with a plurality of fixed clip plate wire grooves, and one end of the moving clip plate is correspondingly provided with a plurality of moving clip plate wire grooves; the moving clip moving control mechanism is installed in the fixing clip housing and includes a control board, a lead screw motor, a rechargeable battery, and a control button. The control board is respectively connected to the lead screw motor, the rechargeable battery, and the control button. The output end of the lead screw motor is connected to a lead screw, and a connecting block connected to the moving clip plate is threadedly connected to the lead screw.

[0009] Further, the fixing clip housing has a handle formed by a handle hole.

[0010] Further, it further includes an indicator light, which is connected to the control board and is arranged on the side of the fixing clip housing.

[0011] Further, the control button is arranged on the top surface of the fixing clip housing.

[0012] Further, the moving clip plate has a support plate and a moving plate, and the moving plate is slidably connected to the support plate.

[0013] Further, at the wire groove of the fixed clamping plate and the wire groove of the movable clamping plate, the type of wire that should be placed in each wire groove is marked, and three wire groove colors of yellow, green, and red are used to distinguish three-phase electricity.

[0014] Further, the control button has three gears, namely the forward gear, the neutral gear, and the reverse gear.

[0015] The second aspect of the present invention is to provide a method for using an electric energy meter wiring fixing clip device, including:

[0016] S1, the operator holds the handle and places the electric energy meter wiring fixing clip device on the line of the electric energy meter to be replaced from top to bottom or from bottom to top;

[0017] S2, set the control button to the forward gear to turn on the power, the lead screw motor rotates forward, pushing the wire groove of the movable clamping plate forward. After moving in place, the wire groove of the movable clamping plate and the wire groove of the fixed clamping plate move away from each other to insert the cable;

[0018] S3, when the control button is pressed to the neutral gear, the power supply is turned off and the lead screw motor stops operating;

[0019] S4, place the corresponding cable into the corresponding wire groove according to the label;

[0020] S5, when the control button is pressed to the reverse gear, the power supply is turned on and the lead screw motor rotates in reverse, pulling the wire groove of the movable clamping plate backward;

[0021] S6, after moving in place, the contact switch is turned on, the indicator light is on, and the wire groove of the movable clamping plate and the wire groove of the fixed clamping plate are clamped to each other to fix the cable.

[0022] The advantages and positive effects of the present invention are:

[0023] 1. The present invention optimizes the structure of the traditional fixture that closes and clamps the upper and lower clamping plates to the structure that closes the wire grooves left and right to clamp the line, reducing the requirement for the operating space; and locks the exposed copper wire through the wire groove. Since the wire groove has a clamping effect on the wire and each wire groove is independent of each other, it is possible to avoid the short circuit caused by the contact between wires and the occurrence of electric shock accidents for the staff.

Detailed Description of the Embodiment

[0032] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited thereby.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0034] As Figures 2 - 4 shown, the present invention provides a wiring fixing clip device for an electric energy meter, including: a fixed clip housing, a moving control mechanism for the movable clamping plate.

[0035] As Figures 2 - 3As shown in the figure, the fixed clip housing includes a fixed clamping plate 11 and a movable clamping plate 12. One end of the fixed clamping plate 11 is provided with a plurality of fixed clamping plate wire grooves 111, and one end of the movable clamping plate 12 is correspondingly provided with a plurality of movable clamping plate wire grooves 121. For the convenience of carrying, a handle composed of a handle hole 13 is provided on the fixed clip housing. In a specific embodiment, the movable clamping plate 12 has a support plate 122 and a movable plate 123, and the movable plate 123 is slidably connected to the support plate 122. Compared with Figure 1 In the electricity meter wiring fixed clip in [reference], operating space is required both above and below the line during use. In this application, only the fixture use space needs to be reserved above or below, reducing the requirement for operating space and increasing the usage scenarios of this application.

[0036] During the design process of this electricity meter wiring fixed clip device, considering that when making the wire grooves on the electricity meter wiring fixed clip device, it is usually encountered that the tail wires of the meter are of the same color and thickness. At this time, when using a general electricity meter wiring fixed clip to fix the tail wires, it is very easy to confuse the voltage, current of different phases and the incoming and outgoing current of the current. Therefore, the type of wire that should be placed in each wire groove can be marked at the fixed clamping plate wire grooves 111 of the fixed clamping plate 11 and the movable clamping plate wire grooves 121 of the movable clamping plate 12, and three wire groove colors of yellow, green and red are used to distinguish the three-phase electricity. The staff can directly fix several tail wires of the meter in the wire grooves in sequence without additional marking of the wires, improving the replacement efficiency of the electricity meter, avoiding incorrect wiring and reducing the incidence of metering failures.

[0037] As Figure 3 shown in the figure, the movable clamping plate movement control mechanism is installed in the fixed clip housing, including a control board 21, a lead screw motor 22, a rechargeable battery 23 and a control button 24. The control board 21 is respectively connected to the lead screw motor 22, the rechargeable battery 23 and the control button 24. The output end of the lead screw motor 22 is connected to a lead screw 221, and a connection block 124 connected to the movable clamping plate 12 is threadedly connected to the lead screw 221. According to the forward and reverse rotation of the lead screw motor 22, the connection block 124 and the movable clamping plate 12 reciprocate on the lead screw 221. After the placement and fixation of the line are completed in this application, the movable clamping plate 12 can be tightened by using the control button 24 to fix the entire device, so as to ensure that the wire will not move or fall off during the operation. Specifically, the control button 24 is arranged on the top surface of the fixed clip housing. Among them, the control button 24 has three gears, namely the forward gear, the neutral gear and the reverse gear. In order to facilitate the confirmation of the state of the electricity meter wiring fixed clip device, an indicator light 25 is also included, which is arranged on the side surface of the fixed clip housing, and the indicator light 25 is connected to the control board 21. In this application, the line is automatically clamped by triggering the control button 24, reducing the operation amount of the operator. At the same time, there is no need for the operator to manually close the wire groove, reducing the probability of the operator contacting the line, thereby improving the operation safety.

[0038] As Figure 4 shown, the present invention also provides a method for using a wiring fixing clip device for an electric energy meter, which can improve the replacement efficiency of the electric energy meter, avoid incorrect wiring, reduce the incidence of metering failures, and reduce the occurrence of electric shock hazards. In the present invention, different wiring fixing clip devices can be set for different metering devices. For example, the number of wire grooves and wire sequence markings of the wiring fixing clip device set for a three-phase three-wire meter can be different. The specific content includes the following:

[0039] S1. The operator holds the handle and places the wiring fixing clip device for the electric energy meter on the line of the electric energy meter to be replaced from top to bottom or from bottom to top;

[0040] S2. Set the control button 24 to the forward gear to connect the power supply. The lead screw motor 22 rotates forward, pushing the moving clamping plate wire groove 121 forward. After moving in place, the moving clamping plate wire groove 121 and the fixed clamping plate wire groove 111 move away from each other to insert the cable;

[0041] S3. When the control button 24 is in the middle gear position, the power supply is turned off and the lead screw motor 22 stops operating;

[0042] S4. Place the corresponding cable into the corresponding wire groove according to the marking;

[0043] S5. When the control button 24 is in the reverse gear position, the power supply is connected and the lead screw motor 22 rotates in reverse, pulling the moving clamping plate wire groove 121 backward;

[0044] S6. After moving in place, the contact switch is turned on, the indicator light 25 is on, and the moving clamping plate wire groove 121 and the fixed clamping plate wire groove 111 are clamped to each other to fix the cable.

[0045] When the present invention replaces the user-side metering device, it can achieve live replacement and safety protection, improve the replacement efficiency of the electric energy meter, avoid the incidence of metering failures, and eliminate the safety hazards of live meter replacement on site.

[0046] The wiring fixing clip device of the present invention can indicate the corresponding wire type through the wire groove and distinguish three-phase electricity, avoid incorrect wiring, and at the same time, the live wires are made independent of each other through the wire groove to avoid short circuits caused by mutual contact, so as to avoid electric shock of the staff caused by the exposed wires contacting the meter box. In addition, the present invention uses the structure of the fixed clamping plate wire groove 111 and the moving clamping plate wire groove 121 closing left and right to clamp the line, reducing the requirement for the operating space. At the same time, the line can be automatically clamped by the moving clamping plate moving control mechanism, which improves the automation degree of the solution and further reduces the possibility of electric shock of the staff.

[0047] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
