Description

A Portable Universal Type Insulator String Bottle Holder

technical field

The utility model relates to the technical field of power transmission, in particular to a portable general-purpose insulator bottle holder used for live replacement of 330kV tension-resistant double-string insulators.

Background technique

At present, when the 330kV tension-resistant double string insulators are replaced while the transmission line is live, the bottle holders used are of many types, heavy, and difficult to transport and install. One of the production and management goals of electric power enterprises is to reduce the outage time of electric power equipment and improve the company's power supply reliability and economic benefits. At present, in the company's 330kV transmission lines, nearly 95% of the strain towers are connected by double-connected insulators. Now the replacement of the strain-resistant double-connected strings with electricity mainly adopts ordinary and reinforced bottle holders. Due to the number of line insulator strings (22~ 24 pieces) and length of insulator strings (3.42~3.72m) in different provinces, each maintenance team needs to prepare a variety of supporting bottle holders, and the traditional bottle holders have a large mass (30~40 Kg), and the currently used The complex structure of live working tools makes it difficult to complete the work; in addition, when the line span and wire tension are small, the insulator string will form a large natural catenary bending, and the ordinary and reinforced bottle holders used by various units They are all designed horizontally and cannot be installed in place at all, which makes live work on the 330kV tension double insulator string very difficult. There are mainly deficiencies in the following aspects:

1. Not universal. There are many types of tension insulators used in transmission lines in the province.

There are ordinary porcelain insulators, anti-pollution insulators, three-umbrella insulators, composite insulators, etc. There are many types and types of insulators. In order to work normally, each type of insulator only

Can use matching bottle holder, not only invest a lot of money, but also very inconvenient to manage, transport, use.

2. It is impossible to replace the insulator string with large bending degree. The existing bottle racks basically use tubes

Type insulating material and metal material are assembled together, the overall straight design of the bottle holder, no

Replacement of insulator strings with large bends in wire tension files such as terminal towers.

3. Heavy weight. The weight of the existing bottle racks is generally tens of kilograms, and the transportation is extremely inconvenient. Because of the heavy weight, it is difficult to install them in place, and there are certain safety risks.

Aiming at the above problems, a portable and general-purpose bottle holder is developed, which is used for live replacement of 330kV tension tower tension series double-connected whole string insulators.

Contents of the invention

The technical problem to be solved by the utility model is to provide a portable and general-purpose bottle holder for the deficiencies of the existing technology, which is used for live replacement of the portable and general-purpose type insulator bottle holder.

The utility model is a portable general-purpose insulator bottle holder through the following technical scheme: a portable general-purpose insulator string bottle holder includes a closed card, a steering connector, an epoxy resin board, and a balance bar. Both ends of the closed card are vertically connected to the upper end of the epoxy resin board through the steering connector, and the lower end of the epoxy resin board is horizontally connected to the balance bar through the steering connector.

Compared with the prior art, a portable and universal insulator string bottle holder of the utility model has the following beneficial effects: the utility model is of a rectangular frame type, and the closed card is installed on the insulator when in use. The steel cap at the third insulator on the side of the string wire, while the utility model closed card is easy to operate when installed, the installation span of the bottle holder is small, only the length of the three insulators, and is not affected by the bending of the insulator string. The pulley used in conjunction with the bottle holder of the utility model is installed on the curved plate clamp on the side connecting plate of the insulator string wire, and the tail end of the lifting rope passes through the pulley on the cross arm of the power transmission tower and the pulley of the pulley and is fastened to the lower end of the bottle holder for balance. The first end of the lifting rope passes through the hand winch installed at the foot of the tower and then hangs to the ground. When the insulator string is disengaged from the connecting plate, the ground operator slowly releases the lifting rope, and the insulator string will slowly descend to a natural drooping state. The utility model is a portable general-purpose insulator bottle holder, which will change the single status quo of live replacement or power outage maintenance of 330kV tension-resistant double-string insulators in the system of Qinghai Provincial Electric Power Company, and can solve the live or power outage maintenance of 330kV insulators. The weight of the bottle holder used when stretching the entire string of double-string insulators is too heavy, the scope of application is limited, and the transportation and storage are difficult. To achieve the purpose of reducing the intensity of the staff, improving work efficiency and reducing costs.

The utility model is a light-weight, wide-ranging, and easy-to-operate bottle holder for live replacement of 330kV tension-resistant double-string insulators, which can completely replace the traditional ordinary type bottle holder and reinforced bottle holder for live replacement of 330kV tension-resistant double insulators. The function of the whole string of insulators can meet the requirements of both live work and power outage maintenance.

The bottle holder of the utility model has the following advantages:

(1) It is convenient for the transportation of tools and utensils. The portable bottle holder of the utility model can be installed in any motor vehicle, and the transportation is very convenient.

(2) It is convenient for human transportation. Most of the transmission line towers are erected in high mountains and big ridges. During the maintenance work, it is often difficult for vehicles to reach the tower position, which requires manpower to transport tools up and down the mountain. The weight of the portable bottle holder of the utility model is only 7Kg, and the transportation is quite light.

(3) The portable and general-purpose bottle holder of the utility model is not limited by the bending degree of the insulator string. The portable and general-purpose bottle holder of the utility model only needs to bridge three insulators for medium installation, so it is not limited by the curvature of the insulator strings, and the replacement task can be completed regardless of the horizontal insulator strings or the insulator strings with large curvature.

(4) The portable and general-purpose bottle holder of the utility model has good general characteristics and is not limited by the number of insulators. Only one pair of portable bottle holders of the utility model can replace insulator strings of different numbers and lengths.

(5) The portable and universal bottle holder of the utility model can facilitate the replacement of insulator strings of different tonnages. The tonnage of 330kV strain insulators is commonly used to be 160KN and 210KN. Due to the different parameters, the size of the steel cap of the insulator is also inconsistent. Yes, and each grass-roots unit with different tonnage closed cards has ready-made configurations.

(6) Conducive to moisture-proof tools. Because of the short length and small volume of the utility model, the portable bottle holder can be directly loaded into the interior of the vehicle box without being affected by special weather.

(7) Can improve operational safety. The utility model has the advantages of portability and versatility, and the main stressed part of the supporting bottle adopts a closed card, and is equipped with a reliable locking device, and because the hoisting point of the lifting rope is located at the side connecting plate of the wire, the insulator string is in contact with the tower material during the falling process. There will be no friction and collision, and safe and reliable operation can be guaranteed in the whole process of use.
