Abstract
The utility model discloses a 220kV guide rod type casing pipe voltage-sharing ball insulation protective structure. The 220kV guide rod type casing pipe voltage-sharing ball insulation protective structure comprises a 220kV guide rod type casing pipe voltage-sharing ball, wherein crepe paper is wrapped outside the 220kV guide rod type casing pipe voltage-sharing ball. The size of the crepe paper is 0.65*320mm, and the insulation thickness of the crepe paper is 4mm per side. The 220kV guide rod type casing pipe voltage-sharing ball insulation protective structure is simple, quick, and convenient to operate, tight and firm in insulating layer, and not prone to dropping off, and avoids the problems that a modeling insulating part is long in manufacturing cycle and high in cost, the manufacturing defects are not prone to being found and the like. The voltage-sharing ball which is wrapped with the crepe paper outside carries oil to transport and store along with a transformer mounting seat, field installation is convenient, insulation moisture can be effectively avoided in the processes of transportation and installation, and safe running of equipment is guaranteed.
Description
Technical field
The utility model relates to the power transformer technical field, relates in particular to a kind of 220kV guide rod type sleeve pipe voltage equalizing ball insulating protection structure.
Background technology
In the charged voltage equalizing ball in bushing shell for transformer lower end is usually located at below transformer body fuel tank case lid or case lid raises seat, should keep certain insulation distance between other parts of charged voltage equalizing ball and body, when insulation distance can't meet the demands, must take corresponding measure to carry out insulating protection to voltage equalizing ball.220kV level transformer normally installed " cup " formation type insulating part additional on the sleeve pipe voltage equalizing ball in the past, fixed with the stay stretching between " cup " formation type insulating part and lead-in wire.Because the molded insulator fabrication cycle is long, and be inconvenient to install, molded insulator makes moist when preventing disassembled for transport, also need make private carrier, and use cost is higher, for this reason, seeks a kind of more efficient safeguard structure very necessary.
The utility model content
The utility model purpose is exactly in order to make up the defective of prior art, a kind of 220kV guide rod type sleeve pipe voltage equalizing ball insulating protection structure that can effectively solve the problems of using the molded insulator existence in traditional structure to be provided.
The utility model is achieved through the following technical solutions:
A kind of 220kV guide rod type sleeve pipe voltage equalizing ball insulating protection structure includes 220kV guide rod type sleeve pipe voltage equalizing ball, at described 220kV guide rod type sleeve pipe voltage equalizing ball coated outside crimped paper.
Described crimped paper is of a size of 0.65*320mm, and insulation thickness is every limit 4mm.
Voltage equalizing ball with the outsourcing insulation during inserting or withdrawing sleeves transportation takes off, and immerses in transformer oil and preserves.
The utility model has the advantages that: the utility model is simple and quick, the insulating barrier close and firm, difficult drop-off, avoided the molded insulator fabrication cycle long, cost is high, the ND problem of manufacturing defect, the voltage equalizing ball of outsourcing crimped paper transports and deposits with power transformer enclosure band oil, on-the-spot easy for installation, can effectively avoid humidified insulation in transportation, installation process, guarantee equipment safety operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
