Description

Spring stretching buckling type transparent insulation box

Technical Field

The utility model relates to the technical field of distribution transformer protection devices, in particular to a spring stretching and buckling type transparent insulation box.

Background

Distribution transformers are one of the important electrical devices in power systems that can function to transform voltage, transfer electrical energy. The conventional installation mode of the transformer used for the overhead line of the power distribution network at the present stage is to install the transformer on a exposed column; moreover, the location is often in a remote area. The terminal heads of the transformer are in a naked state, so that short-circuit accidents caused by overlapping of small animals such as birds and beasts or foreign matters with the exposed terminal heads are effectively avoided; meanwhile, the corrosion of frost, pollution flashover and cauterization, acid rain, salt fog and harmful chemical gas to the inlet and outlet wires of the transformer is prevented; in addition, the accident of personal injury and death caused by the fact that pedestrians touch the exposed electric contact by mistake is avoided. According to the current power grid construction specification requirements, the transformer terminal is preferably provided with an insulating safety protector. The traditional protective materials are mostly insulating sheaths prefabricated by silicone rubber and heat-shrinkable materials, and are one of the most basic and reliable means.

In addition, there are also proposals for protecting distribution transformers using insulating oil, for example, chinese patent CN111640560B discloses a natural ester insulating oil distribution transformer comprising a sealed housing covering the transformer body; the inside of the sealed shell is filled with insulating oil which is fully immersed in the transformer body, an oil storage cabinet filled with the insulating oil is arranged on the sealed shell, the oil storage cabinet is connected with the inside of the sealed shell through a pipeline, and a transformer respirator for balancing the pressure inside the oil storage cabinet is arranged on the oil storage cabinet; the oil cooling mechanism for cooling insulating oil is arranged on the outer side of the sealing shell, the guide mechanism matched with the oil cooling mechanism and used for guiding the flow direction of the cooled insulating oil is arranged in the sealing shell, the cooled insulating oil is sprayed out to the heating coil of the transformer through the guide mechanism, heat exchange can be carried out with the heating coil of the transformer rapidly, and the cooling efficiency of the transformer is improved.

However, with the transition of power distribution technology, the need for complete insulation of power distribution networks is also increasing. Therefore, higher requirements are put on the structural rationality, the application performance and the installation mode suitability of the insulating shielding product. Because the traditional protection scheme is mostly soft colloid materials, the device is only suitable for installation of a power failure pole-climbing tower or an insulating bucket arm vehicle, has high installation cost and low efficiency, and can not meet the operation requirement of the reliability of the power grid at present. Meanwhile, the traditional insulating wrapping mode and the non-transparent silica gel material also bring disadvantages to equipment operation and maintenance. This is because the sheath made of silica gel and heat shrinkage material is heated to shrink, and the transformer terminal head is kept at a certain temperature in a normal state in the operation process. Therefore, the thermal shrinkage performance of the traditional sheath wrapping insulation is affected, and the terminal is tightly wrapped in the operation process, so that the heat dissipation of the equipment is affected. Meanwhile, as the non-transparent protective material can shield the vision of operation and maintenance personnel, the operation state of the terminal head of the equipment cannot be intuitively observed by the operation and maintenance personnel in line inspection, the hidden danger of the operation of the equipment cannot be timely found, and the hidden danger is buried for the safe operation of a power grid.

Comprehensively, the prior art mainly has the following defects:

firstly, the traditional sheath is made of non-transparent materials, so that the sight of operation and maintenance personnel can be blocked, and the operation hidden troubles such as equipment defects, arc burning marks of a wiring terminal and the like can not be observed;

secondly, the traditional silica gel and heat-shrinkable material sheath is shrunk by heating, and after the installation and operation time of the sheath are long, the transformer terminal is tightly wrapped, so that the heat dissipation and ventilation of equipment are affected; and accumulated dust and water are also easy to be caused.

And thirdly, the traditional sheath is a silica gel soft body and can only be installed in a handheld manner, and the operation mode can only be power failure ascending operation or installation of an insulating arm vehicle.
