Description
Technical field
This utility model relates to transformator, and particularly a kind of loaded capacity regulating voltage regulating transformer low-voltage lead connects assembly.
Background technology
Loaded capacity regulating voltage regulating oil immersion-type distribution transformer be a kind of have in same transformator two kinds of different capabilities, can root
Automatically change high pressure winding and the connected mode of low pressure winding according to load change, change high pressure winding voltage and can hold in difference
The distribution transformer of the lower reliability service of amount.The visual plant realizing capacity switching and voltage change is then that loaded capacity regulating voltage regulating is opened
Close, be placed in oil tank of transformer together with two independent parts of this switchgear and transformer body, be immersed in insulating oil,
Realize key link that transformer body is connected with switchgear then for lead portion.
Winding, as the heart of transformator, plays transmission power, changes voltage and current and important function, the electricity of high pressure winding
Pressure input can make the output of low pressure winding meet and use the magnitude of voltage required.The height of loaded capacity regulating voltage regulating oil immersion-type distribution transformer
Pressing the multiple lead-in wire of winding to lift one's head with loaded capacity regulating voltage regulating and switch corresponding high-voltage connection terminal connection, low pressure winding is multiple to go between out
Head need to switch corresponding low-voltage terminal with loaded capacity regulating voltage regulating and connect.So the arrangement of lead-in wire, lead-in wire material, lead format
The reliability of design, the operability of production technology of this kind of transformator is played an important role.
This type of transformator for high-pressure side tapping voltage is 5 grades: every phase high pressure winding has 7 lead-in wires to lift one's head, three-phase is common
21 lead-in wires are lifted one's head；Low pressure winding has 5 lead-in wires to lift one's head, and three-phase totally 15 lead-in wires are lifted one's head；Totally 36 lead-in wires on transformer body
Lift one's head be all connected to switch on binding post.For meeting the connection of transformer body winding and switchgear, transformator is high
Pressure winding current little, the usual way of transformator producer be high-pressure side paper using take all of copper conductor be connected to switch on；Low pressure winding electricity
Stream is big, it is common practice that be connected on switch with many copper strap wires or copper bar.For circular copper wire or many copper strap wire connected modes,
It is each welded to transformer body lead-in wire lift one's head, for copper bar connected mode, also takes welding or bolt connecting mode.
Connect with copper strap wire and copper bar and mainly have following shortcoming:
1, low pressure winding uses copper strap wire connected mode: this kind of mode need with individually meet the copper cash of electrical current carriers with
Winding tap lead-in wire uses oxygen welding or acetylene welding, and welding can produce naked light in production scene, and on the one hand burning things which may cause a fire disaster can be to change
Depressor device body produces pyrolytic damage, needs direct labor carry out the Local cooling of winding and block safeguard procedures, and needs after welding
Want grinding process solder joint, have metal dust and produce.This kind of mode influences whether safety in production factor and reduces labor efficiency；
2, low pressure winding uses copper bar connected mode: need 15 copper bars to go between out from Transformer Winding altogether due to low voltage three-phase
Head is connected to switch, and copper bar width dimensions is relatively big, and can not arbitrarily change direction in space, so copper bar need to be taked repeatedly to roll over
Curved just can connect on switch, and under could need to placing in bigger space.Thus can increase the width of fuel tank, increase
Material cost, and when making copper bar work consuming, reduce production efficiency greatly.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of loaded capacity regulating voltage regulating to become
Depressor low-voltage lead connects assembly.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of loaded capacity regulating voltage regulating transformer low-voltage lead connects assembly, adjusts with there being load for transformer low voltage winding body
Hold the connection between tap changer, the first binding post including copper cable, being positioned at copper cable one end, be positioned at the copper cable other end
The second binding post, the first binding post is connected with transformer low voltage winding body by fixing connector, the second terminals
Son is connected with loaded capacity regulating voltage regulating switch by fixing connector, is cased with insulating protection pipe outside described copper cable.
Described first binding post, the second binding post and copper cable are the entirety compressed.
Described fixing connector is bolt.
Described copper cable has two or more than two, and it is a segmentation that different Cu cable compresses linking by cold rolling copper pipe
The copper cable connected.
Described insulating protection pipe is wrinkle paper tube.
Described copper cable has many, transformator is provided with wooden splint and is clamped by many copper cables.
The beneficial effects of the utility model are:
1, the safety that raising produces:
Use copper cable, cold rolling copper pipe, binding post, wrinkle paper tube to coordinate as pin configuration, can substitute for original work
, there is not the use fuel such as oxygen, acetylene in production process, flare will not being produced, so carrying greatly in the welding method in skill
The high safety produced.
2, the standardization level of material is higher:
The big I of leader cable determines several fixing rule according to the electric current density that transformer capacity size is determined
Lattice, use unit cable as lead-in wire, can use many Electricity Federations when electric current is bigger when electric current is less.So the versatility of cable is relatively
By force, the standardization level of material is higher.
3, production efficiency is improved:
Owing to the structure of this gage system is relatively easy, the instrument used in production process is less, can save original welding
Welding, lead-in wire in mode are wrapped up, go between 3 procedures such as arrangement, so the time used by unit product that completes can save a lot, and pole
Big improves production efficiency.
4, good looking appearance:
Use copper cable as the connector between Transformer Winding and switchgear, copper cable can meet electrically away from
Free bend and layout in the space of safety, when there is many lead-in wires, all can accomplish rounding off, there is not hard bending
And repeatedly bending.All copper cables can carry out unifying fixing and colligation, good looking appearance with wooden splint.
