Description
技术领域 technical field
本发明属于测试钳技术领域，尤其涉及一种多功能可伸缩式电力高空测试钳及其使用方法。 The invention belongs to the technical field of testing pliers, and in particular relates to a multifunctional retractable electric high-altitude testing pliers and a method for using the same.
背景技术 Background technique
新建及改造的变电站新安装的电流互感器必须做CT测试变比升流试验。在测试过程中的升流线固定流程十分繁琐，往往需要占用很大的人力和时间，严重影响此工作的工作效率和工作人员的人身安全。 Newly installed current transformers in newly built and renovated substations must undergo CT test transformation ratio up-current tests. During the testing process, the process of fixing the ascending streamline is very cumbersome, and often requires a lot of manpower and time, which seriously affects the work efficiency of this work and the personal safety of the staff.
升流试验往往需要载流量大的铜导线，一般为Φ50以上。传统升流试验的方法是施工人员背着升流线上梯子到CT.PT间隔，由于CT.PT间隔上空间狭小，只能也只有能容纳一个人的空间，背着沉重的电流线在上面转身移动极其不方便，稍微不留神就会发生电流线误碰瓷套管发生倾倒和砸坏瓷套管等事故。每次到变电站工作至少要去5－6人，由于试验时需要在“流变”一次侧两端挂接升流试验导线，接线端L1、L2、P1、P2离地面高度一般为4-6米，工作时要使用单梯或升降梯，并需有专人扶持梯子，专人上下传递工具，1人上去挂接升流或升压线；还有操作、记录及监护人员在工作的位置上，安全带也找不到合适的地方固定，根据国家电网电力安全工作规程规定，高处作业安全带不准低挂高用，禁止系挂在移动或不牢固的物件上；如避雷器、断路器、隔离开关、电流互感器、电压互感器等支持件上。另外，由于梯子太高，人在空中感到摆动不稳，即使利用接地线放电后仍有零星感应电麻手，心理上产生恐惧感，所以工作起来很不安全，极易造成工作人员的人身安全事故隐患。 Up-current tests often require copper wires with a large current-carrying capacity, generally above Φ50. The traditional up-current test method is that the construction personnel carry the ladder on the up-current line to the CT.PT interval. Due to the small space on the CT.PT interval, there is only room for one person, and the heavy current line is carried on it. It is extremely inconvenient to turn around and move. Accidents such as accidents such as the current wire accidentally hitting the porcelain bushing and toppling and smashing the porcelain bushing will occur if you are not careful. At least 5-6 people have to go to work in the substation every time. Since the test needs to be connected to the two ends of the "rheological" primary side for the up-current test wire, the height of the terminals L1, L2, P1, and P2 from the ground is generally 4-6 m. When working, use a single ladder or lift, and special personnel are required to support the ladder, pass the tools up and down, and one person goes up to connect the booster or booster line; there are also operating, recording and monitoring personnel at the working position, The safety belt could not find a suitable place to fix it. According to the State Grid Electric Power Safety Work Regulations, the safety belt for high-altitude operations is not allowed to be hung low and high, and it is forbidden to hang on moving or unstable objects; such as lightning arresters, circuit breakers, On supports such as isolating switches, current transformers, and voltage transformers. In addition, because the ladder is too high, people feel unstable in the air. Even after using the grounding wire to discharge, there are still sporadic induction of electric numbness, which creates a sense of fear psychologically. Therefore, it is very unsafe to work, and it is easy to cause personal safety Accident hazard.

In order to meet the experiments at different heights, the insulating rods are divided into 1.2m/section*4 section meters, and 50 square meters*1.2m current wires are built into each insulating rod. Considering the weight and current carrying problems of the current wires, the larger the cross-sectional area of the conductor, the better Well, you can choose 50 square multi-strand copper soft wires, which are light and durable. The metal joints at both ends of the built-in current wire and the outer insulating rod are fixed with pins, so that the built-in current wire and the outer insulating rod are reliably connected. The upper and lower pliers are designed in the olecranon style. The pliers have strong bite strength and a large contact area. The wiring is flexible and firm.

The nose and the rod are connected tightly as a whole and have good electrical conductivity. The newly added voltage line, in addition to the function of raising the current, can complete the production test that requires both current and voltage, such as contact resistance test and loop resistance test. Make the product more powerful. It can withstand the test when the current of 700A passes through the pole for 40 seconds.

The connection between the insulating rods of each section adopts the male and female threaded connection, because the height of the terminals L1, L2, P1, and P2 of the high CT from the ground is generally 4-6 meters. In order to meet the experiments at different heights, the insulating rod 1 is divided into 1.2 meters/section*4 section meters, and each section of the insulating rod 1 has a built-in current line 4 of 50 square meters*1.2 meters. Considering the weight and current carrying problem of the current line 4, the conductor transverse The larger the cross-sectional area, the better. You can choose 50 square multi-strand red copper soft wires, which are light and durable. The metal joints 5 and 6 at both ends of the built-in current wire 4 are fixed with the outer insulating rod 1 with pins 7, so that the built-in current wire 4 and the outer insulating rod 1 are reliably connected. The upper pliers 10 and the lower pliers 11 are olecranon-shaped. The pliers have a large bite strength and a large contact area, and the wiring is flexible and firm. They can clamp cylindrical aluminum stranded wires or rectangular parallelepiped aluminum bars. The pliers head is equipped with serrations, the upper pliers head 10 is provided with upper serrations 12, and the lower pliers head 11 is provided with lower serrations 13, which can easily bite through the oxide layer of the tested equipment for reliable testing. Clamp head bar 8 has spring telescopic device 9, installs telescopic flexible wire 15 and is reliably connected with remaining bar, thereby reliable electric conduction, telescopic flexible wire 15 can be 50 square annealed copper wires. The upper pliers 10 and the lower pliers 11 are connected by metal wires 14, so that they are more tightly connected, and the conduction is reliable and foolproof. At the end of the pole, a 1000A copper nose is led out from the surface of the insulating pole 1 for reliable connection with the current raising equipment, so as to realize the current generation experiment. The nose and the rod are connected tightly as a whole and have good electrical conductivity. The newly added voltage line, in addition to the function of raising the current, can complete the production test that requires both current and voltage, such as contact resistance test and loop resistance test. Make the product more powerful. It can withstand the test when the current of 700A passes through the pole for 40 seconds.
本发明的保护范围不仅仅局限于上述实施例，只要结构与本发明多功能可伸缩式电力高空测试钳的结构相同或相似，就落在本发明保护的范围。 The protection scope of the present invention is not limited to the above-mentioned embodiments, as long as the structure is the same or similar to that of the multifunctional retractable electric high-altitude test clamp of the present invention, it falls within the protection scope of the present invention.
