Description

Technical Field

[0001] The utility model relates to the technical field of accessory parts of voltage transformers, in particular to an insulating sheath for a voltage transformer. Background Technique

[0002] A voltage transformer is an instrument used to transform voltage. The main purpose of voltage transformation by a voltage transformer is to supply power to measuring instruments and relay protection devices, to measure the voltage, power, and electrical energy of a line, or to protect valuable equipment, motors, and transformers in the line when a fault occurs in the line.

[0003] When a voltage transformer is in use, its top connector is connected to an external transformer or other equipment through an electric wire. Since the usage environment is mostly exposed to the natural environment, under the influence of high temperature, low temperature, wind, rain, snow, etc., the connection between the top connector of the voltage transformer and other equipment will age rapidly, and in severe cases, damage will occur. Therefore, an insulating sheath needs to be put on the top connection of the voltage transformer to form protection, improve safety, and extend the service life.

[0004] The existing insulating sheaths at the top connections of voltage transformers are generally sleeved at the connector. When encountering relatively bad weather with strong wind and rain, the sheath is easily blown off, and rainwater will enter the interior from the gaps at the opening of the sheath, resulting in aging and damage of the connection, and the protection effect is not good. We propose an insulating sheath for a voltage transformer. Content of the Utility Model

[0005] The purpose of the utility model is to provide a title of the utility model to solve the problems raised in the above background technique.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An insulating sheath for a voltage transformer, comprising a sheath body. The sheath body is composed of a first connecting sleeve and a second connecting sleeve. A first rain shield is arranged on the outer periphery of the bottom end of the first connecting sleeve. A first plug-in block is connected to the bottom of the first connecting sleeve. A second rain shield is arranged on the outer periphery of the bottom end of the second connecting sleeve. A second plug-in block is connected to the bottom of the second connecting sleeve.

[0008] As a preferred scheme of the utility model, the top surface joints of the first connecting sleeve and the second connecting sleeve, the first rain shield and the second rain shield, and the first plug-in block and the second plug-in block are connected by hot melting.

[0009] As a preferred scheme of the utility model, clamping grooves are opened on the back shells of the first connecting sleeve, the first rain shield, and the first plug-in block.

[0010] As a preferred solution of the present utility model, clamping blocks are provided at the back shells of the second connecting sleeve, the second rain shield and the second plug-in block, and their positions correspond to the clamping grooves.

[0011] The technical effect of adopting the above further solution is that after the top surfaces of the first connecting sleeve and the second connecting sleeve, the first rain shield and the second rain shield, and the first plug-in block and the second plug-in block are heat-melted and connected to form an integral body, the connection between the top of the voltage transformer and external equipment can be sleeved into the opening on the other side for protection. Then, the clamping blocks are clamped into the clamping grooves to close the openings between the first connecting sleeve and the second connecting sleeve, the first rain shield and the second rain shield, and the first plug-in block and the second plug-in block, which can not only protect the connection between the voltage transformer and external equipment, but also have a certain waterproof function to prevent rainwater from entering the interior.

[0012] As a preferred solution of the present utility model, limiting clamping blocks are provided inside the first plug-in block and the second plug-in block.

[0013] The technical effect of adopting the above further solution is that after the connection between the top of the voltage transformer and external equipment is sleeved in, the first plug-in block and the second plug-in block are pressed to be inserted into the circular gap around the top connection head of the voltage transformer. The limiting clamping blocks inside the first plug-in block and the second plug-in block will clamp the outer wall of the connection head, making the fixation more firm and preventing the insulation sheath from falling off.

[0014] As a preferred solution of the present utility model, a third rain shield is heat-melted and connected to the back of the sheath body.

[0015] The technical effect of adopting the above further solution is that the third rain shield protects the part of the wire connected to the connection head of the voltage transformer.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. In the present utility model, after the top surfaces of the first connecting sleeve and the second connecting sleeve, the first rain shield and the second rain shield, and the first plug-in block and the second plug-in block are heat-melted and connected to form an integral body, the connection between the top of the voltage transformer and external equipment can be sleeved into the opening on the other side for protection. Then, the clamping blocks are clamped into the clamping grooves to close the openings between the first connecting sleeve and the second connecting sleeve, the first rain shield and the second rain shield, and the first plug-in block and the second plug-in block, which can not only protect the connection between the voltage transformer and external equipment, but also have a certain waterproof function to prevent rainwater from entering the interior.

[0018] 2. In the present utility model, after sleeving the connection part between the top of the voltage transformer and external equipment, press the first plug-in block and the second plug-in block so that they are inserted into the circular gap around the connection head at the top of the voltage transformer. The limiting blocks on the inner circumferences of the first plug-in block and the second plug-in block will clamp the outer wall of the connection head, thereby making the fixation more firm and preventing the insulating sheath from falling off.
