The technical solution adopted is that:
A kind of voltage transformer, including insulation shell.
Technical points are:
Insulation shell surface is equipped with the first primary connection bolt and the first terminal caps, and the first terminal caps pass through the
One one times screwed pipe connects first fuse one end.
The first fuse other end is equipped with first fuse light cap, and first fuse is inserted into first fuse light cap, the
It is connected between one fuse and first fuse light cap by the first spring.First fuse light cap passes through No. a first guide rod connections
One end of primary coil.
Insulation shell surface is equipped with the second primary connection bolt and the second terminal caps, and the second terminal caps pass through the
21 times screwed pipe connects second fuse one end.
The second fuse other end is equipped with second fuse light cap, and second fuse is inserted into second fuse light cap, the
It is connected between two fuses and second fuse light cap by second spring.Second fuse light cap passes through No. a second guide rod connections
The other end of primary coil.
It is equipped with iron core in insulation shell, secondary coil is arranged on iron core, is equipped with primary coil on the outside of secondary coil.It is secondary
Coil is correspondingly connected with secondary connection inserts.
Switch installs power transformer (voltage transformer) additional, detects line voltage distribution, and provide operation power, power supply for switch
Transformer primary side should configure protection fuse, have stronger UV resistant using silicon rubber-epoxy resin compound inslation
And resistance to outdoor weather ability, and having the features such as fire-retardant, explosion-proof, hydrophobic, product can bear long-term outdoor operation, and have
Anti overvoltage function.
The advantage is that:
Insulation uses silicon rubber composite insulation, and major advantage is that silicon rubber has an excellent hydrophobicity, and outdoor resin
Do not have, and silicon rubber uvioresistant, anti-aging, tracking-resistant corrosion, performance are superior to outdoor resin.Inside uses outdoor tree
Rouge not only effectively increases the outdoor adaptability of mutual inductor, but also cost substantially reduces.
Using fuse in-laid process, it is exhausted traditional outdoor drop-out fuse to be changed into the miniaturization resin haveing excellent performance
Edge fuse is built in A, B, two terminal inners of mutual inductor, effectively reduces mounting complexity, keep mutual inductor any
Direction installation.
Using R shaped iron core, core loss and no-load current are effectively reduced, product institute's carrying load ability increases.And it uses
Low magnetic density designs (0.6T or less), so that mutual inductor is had better anti-overvoltage capacity, and mutual inductor volume is reduced significantly, weight
2/5 is alleviated than traditional type voltage transformer.
Design science, reasonable, original, performance is stable, reliable for operation, has extremely strong practicability and advance.Peace
Dress is convenient, easy to operate, operation cost is low.
