Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a marking and warning device for an air circuit breaker in a power distribution system of an electric power enterprise. Background Art

[0002] Air circuit breakers are power distribution equipment that have been widely used in industrial sites. According to the relevant requirements of GB 26860-2011 "Electric Power Safety Work Regulations - Electrical Part of Power Plants and Substations", circuit breakers in industrial sites must be doubly named and installed with corresponding dual name labels; when performing power outages and other operations during power work, a "Do not close the circuit breaker when someone is working" warning sign must be hung on the operating handle of the circuit breaker.

[0003] Currently, in power distribution systems of power companies, the practice of deploying dual names for circuit breakers is usually to customize metal or plastic labels that are fixed above or near the circuit breakers by riveting or sticking.

[0004] Currently, in the power distribution system of electric power enterprises, the practice of deploying warning signs on the handles of circuit breakers is usually to connect the signs with hanging ropes and hang the warning signs on the handles of air circuit breakers through the hanging ropes.

[0005] Existing warning devices have the following disadvantages:

[0006] (1) The current common deployment method of "Do not close the circuit breaker when someone is working" warning signs makes it difficult to control the risk of objects colliding with the circuit breaker body and causing the circuit breaker to malfunction. Even if the warning sign is hung on the handle of the circuit breaker with a rope, since the circuit breaker body is still exposed, there is a possibility that other objects will collide with the circuit breaker body. If this happens, the circuit breaker may malfunction.

[0007] (2) The current common deployment method of "Do not close the circuit breaker when someone is working" warning signs lacks more effective control over the risk of personnel misoperating the circuit breaker and causing the circuit breaker to malfunction. Even if a warning sign is hung on the handle of the circuit breaker with a rope, personnel may still ignore the warning sign. This deployment method can only serve as a warning, and does not impose stronger constraints on personnel's operations.

[0008] (3) The current common deployment method of "Do not close the circuit breaker when someone is working" warning signs is not reliable enough. Hanging the warning signs on the handle of the circuit breaker with a rope is easy to fall off. Once the rope falls off, the warning signs will lose their warning function, which may cause the operation and maintenance personnel to operate incorrectly and cause safety accidents. And the fallen signs are easy to be lost.

[0009] (4) The current common deployment and removal methods of "Do not close the circuit breaker when someone is working" warning signs are not convenient enough. When it is necessary to deploy or remove warning signs for many circuit breakers, the operation is very cumbersome. When deploying, you need to hang ropes on the handles of the circuit breakers one by one. After removal, these warning signs need to be sorted and stored.

[0010] (5) The current common deployment method of dual-name identification of circuit breakers has poor reliability. During the maintenance of power equipment, when a large number of "Do not close the circuit breaker when someone is working" warning signs are hung on multiple circuit breakers in the distribution board, it is easy for the dual-name signs to be blocked, which may cause the operation and maintenance personnel to make mistakes and cause safety accidents.

[0011] (6) The current common deployment method of dual name identification of circuit breakers is not flexible enough and difficult to change. When the wiring circuit or purpose of the circuit breaker is changed, the relevant identification needs to be customized and installed again, which is a cumbersome process and a large workload.

[0012] (7) Some existing double labeling methods are not aesthetically pleasing. The pasting of paper labels usually requires manual work, which makes it difficult to ensure that they are pasted neatly and can easily become skewed, affecting the appearance of the distribution system.

[0013] (8) The existing deployment method of warning signs is not aesthetically pleasing. When several adjacent circuit breakers are hung with warning signs with ropes, it is difficult to unify the height of each sign, which affects the overall appearance of the electrical cabinet. Summary of the invention

[0014] The technical problem to be solved by the utility model is to provide a marking and warning device applied to air circuit breakers of power distribution systems of electric power enterprises, thereby improving the convenience and safety of the marking and warning deployment.

[0015] In order to solve the above technical problems, the technical solution adopted by the utility model is: a marking and warning device applied to the air circuit breaker of the power distribution system of the power enterprise, including a base, the base includes a horizontal plate and a vertical plate, the back of the vertical plate is used to be bonded to the steel cabinet panel above the circuit breaker, and a flap is rotatably connected at the outer edge of the horizontal plate. The base and the flap are both made of transparent material, and a first slot is provided on the side of the flap.

[0016] Preferably, a foot is provided at the bottom of the flap, and a magnet is provided at the outer end of the foot, so that the flap can be magnetically attracted to the steel cabinet panel above the circuit breaker after being flipped upward.

[0017] Preferably, a second slot is provided on the side of the vertical plate.

[0018] Preferably, the base further includes side panels, which are arranged on both sides of the horizontal panel and the vertical panel.

[0019] Preferably, the base and the flap are made of transparent acrylic material.

[0020] Preferably, identification tags are inserted into the first slot and the second slot.

[0021] The utility model provides a marking and warning device for air circuit breakers in power distribution systems of power enterprises, which has the following advantages:

[0022] (1) The utility model will reduce the risk of other objects accidentally hitting the circuit breaker body and staff accidentally operating the circuit breaker after the warning sign is deployed. When the device is in the warning display state, the flap is in the down state. At this time, the flap covers the circuit breaker body, and the side with the warning sign faces outward, which is very conspicuous. If other objects are about to accidentally hit the circuit breaker, they will be blocked by the flap and will not hit the circuit breaker body. If someone wants to operate the circuit breaker, they must first flip up the flap. At this time, the human eye will see the warning sign on the flap, thereby achieving "being warned before the wrong operation". Therefore, whether it is an object accidentally hitting the circuit breaker or a person accidentally operating the circuit breaker, both types of risks will be reduced by the present invention.

[0023] (2) The utility model will make the deployment of warning signs more reliable. Warning signs deployed by the device will hardly fall off.

[0024] (3) The utility model will make the deployment of dual marking more reliable. The paper strip with the dual marking written on it is placed in the slot and is almost impossible to fall off.

[0025] (4) The utility model makes it easier to modify the dual logo. When the dual logo needs to be changed, only the corresponding paper strip in the slot needs to be replaced.

[0026] (5) The present invention will make the deployment, removal, storage and organization of warning signs easier. When there is no need to deploy a warning sign on the circuit breaker, the device is in an upward flip state, the magnetic patch is attracted to the electrical panel cabinet, and the side of the flap with the circuit breaker dual logo and normally on / normal off information is exposed to the outside. When it is necessary to deploy a warning sign, it is only necessary to manually flip down the flap of the device, so that the side of the flap with the warning message is exposed to the outside, and at the same time, the dual logo on the base of the device is also exposed to the outside, realizing the function of the warning sign. When it is necessary to remove the warning sign, it is only necessary to restore the flap of the device to the upward flip state. In addition, the traditional practice regards each warning sign and dual logo as separate and independent objects, while the present invention brings the warning sign and dual logo together, avoiding the workload of storing and organizing warning signs from the source.

[0027] (6) The utility model will make the deployment of double signs and warning signs more beautiful. As long as the device body is installed and arranged neatly, the paper strips placed in the slot will also be neat. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 1-4 As shown, a marking and warning device for air circuit breakers in a power distribution system of an electric power enterprise comprises a base 1, wherein the base 1 comprises a horizontal plate 2 and a vertical plate 3, the back of the vertical plate 3 is used to be bonded to a steel cabinet panel above the circuit breaker, a flap 4 is rotatably connected to the outer edge of the horizontal plate 2, the base 1 and the flap 4 are both made of transparent material, and a first slot 5 is provided on the side of the flap 4.

[0036] Preferably, a foot 6 is provided at the bottom of the flap 4, and a magnet 7 is provided at the outer end of the foot 6. The magnet 7 enables the flap 4 to be magnetically attracted to the steel cabinet panel above the circuit breaker after being flipped upward.

[0037] Preferably, a second slot 8 is provided on the side of the vertical plate 3 .

[0038] Preferably, the base 1 further includes side panels 9 , which are arranged on both sides of the horizontal panel 2 and the vertical panel 3 .

[0039] Preferably, the base 1 and the flap 4 are made of transparent acrylic material.

[0040] Preferably, identification plates are inserted into the first slot 5 and the second slot 8 .

[0041] The device is made of transparent acrylic material and is structurally divided into two main parts, namely the base and the flip cover, both of which are equipped with label slots for inserting paper-printed dual names and warning signs, such as Figure 5 , 6 As shown. They are connected by a rotating shaft to integrate the dual names of the air circuit breaker and the warning sign "Do not close the circuit breaker when someone is working" into one. The back of the base is fixed to the steel cabinet panel above the corresponding circuit breaker with glue.

[0042] The device has two functional states, namely, a name identification state and a warning identification state, and the two states can be easily switched manually.

[0043] In the name identification state, the cover of the device is in the upward state and is reliably adsorbed and fixed on the top of the corresponding circuit breaker through the strong magnetic force of the neodymium magnet, realizing the dual name identification of the corresponding circuit breaker and the display of information such as the position status of the circuit breaker during normal operation.

[0044] When it is necessary to switch to the warning sign state, just flip the cover to let the neodymium magnet break away from the strong magnetic adsorption, and then the cover can fall and flip over. After the cover is flipped to the downward state, the "Do not close the circuit breaker when someone is working" warning sign can cover the corresponding circuit breaker. The circuit breaker cannot be closed without flipping up the cover, which prevents objects from colliding with the circuit breaker body and prevents people from operating it incorrectly.

[0045] After the wiring and use of the corresponding circuit breaker are changed, the identification function can be changed by simply reprinting the double name label paper in the label slot. The convenience of this device is:

[0046] (1) Based on the fact that most electrical cabinets are made of magnetizable alloys, the utility model uses the magnet-engaged / non-engaged state to correspond to the up / down state of the device, that is, the name identification state and the warning identification state, and then corresponds to the removal / deployment state of the warning sign. This feature makes it very convenient to switch between the two states, making the setting and removal of the warning sign simple.

[0047] (2) The utility model reduces the risk of circuit breaker misoperation caused by object collision and human error. When the warning sign is deployed, that is, the device is in the warning sign state, the flap is in the flip-down state, at which time the flap covers the circuit breaker body, and the side with the warning sign faces outward. If an object collides, it will be blocked by the flap and will hardly touch the circuit breaker body. If a person tries to operate the circuit breaker, the person must first flip up the flap, and at this time there is a conspicuous warning sign on the flap, and the person will be warned by seeing the warning sign before flipping up the flap. Therefore, whether it is an object collision or human error, these two types of risks that may cause circuit breaker misoperation can be reduced by the present invention.

[0048] (3) The utility model makes the deployment of warning signs reliable. The present invention uses a device permanently fixed on the electrical panel cabinet to deploy warning signs, replacing the traditional deployment method of temporarily hanging them on the circuit breaker handle with a rope. Ensure that the device is installed reliably, and the warning sign will not fall off after deployment.

[0049] (4) The utility model makes the deployment of dual identification reliable. The utility model transforms the pasting of dual identification labels into fixed installation of the device base. Compared with the traditional method of pasting labels, the fixed installation of the device base has more technical means to ensure its reliability.

[0050] (5) The utility model combines the warning sign and the dual sign together. Compared with the traditional practice of treating each warning sign and the dual sign as separate and independent objects, the utility model avoids the workload of storing and organizing the warning sign.

[0051] (6) The utility model makes it easy to replace the dual label and the warning sign. When it is necessary to replace the dual label or the warning sign, only the paper in the device slot needs to be replaced. The traditional method requires remaking the dual label or the warning sign, which has a higher manufacturing cost and time than paper.

[0052] (7) The utility model makes the deployment of dual signs and warning signs more aesthetically pleasing. Traditional practices regard each deployment of a dual sign or warning sign as a separate installation operation, and each installation operation may introduce installation position deviations, thereby having a negative impact on the overall aesthetic effect. The present invention allows all installation position deviations to be concentrated in the first and only installation work of the device base. After ensuring that the device base is installed neatly and beautifully, the deployment of dual signs and warning signs only requires replacing the corresponding paper pieces. In this process, no new installation position deviations are generated, and there will be no negative impact on the overall aesthetic effect.

[0053] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
