In line support frame, and with main bus-bar A, bus B and bus C through bolt fastening；Catch-all support frame through bolt and low-pressure side every
Plate is fixed, and catch-all is fixed on switch support frame, and catch-all is suitable for reading to be connect with main bus-bar, the change of lower mouth and transformer room
The connection of depressor low pressure side terminal, forming circuit.
Moreover, the low-pressure side partition is fastenedly connected multiple support frame a with tapping screw, made on each support frame a
Four internal screw thread mounting holes out, each support frame a pass through internal screw thread mounting hole and bolt and are fastenedly connected with breaker, the open circuit
Wherein one end bolt fastening of device and adapter, the other end of adapter with hexagon socket head cap screw be clamped on bus a, bus b and
On bus c.
Moreover, the breaker be In=630A breaker or In=250A breaker, the adapter be with
Matching used In=630A adapter or In=250A adapter.
The advantages and positive effects of the utility model are as follows:
The utility model uses enclosed busbar mounting means, does not punch between component and bus, with hexagon socket head cap screw card
It is tightly connected.Guarantee that complicated connection conducting position is not exposed, effective pre- protection against electric shock ensure that the safety and reliability of power supply.
The utility model makes it be fixed on support frame a using modular mounting means by taking In=630A breaker as an example
After upper and In=630A adapter one end fastens, and the adapter other end is plugged on bus, keeps conductor complete with hexagon socket head cap screw
Contact forming circuit.This modular mounting means greatly improves work efficiency, and simplifies process flow, saves work
When, reduce production cost.
The utility model uses modular mounting means, can reserve spare installation space, add or reduce at any time and is standby
Use load.Relative to traditional Installation Modes, modular mounting means can make the change of breaker, increase operation convenient
It is more.

Specific embodiment
Embodiment of the utility model will be described in detail below with reference to the attached drawings, it should be noted that the present embodiment is narrative
, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of preassembled transformer station low-pressure side mounting structure, including casing of preinstalled type substation 16, catch-all 1, bus
A4, bus b5, bus c6, main bus-bar A8, main bus-bar B9 and main bus-bar C10.
The innovative point of the utility model is: low-pressure side partition 3, three bus branch are installed in casing of preinstalled type substation
Support 7 is sequentially arranged on low-pressure side partition through tapping screw, in bus a, bus b and bus c insertion bus support frame, and with
Main bus-bar A, bus B and bus C are through bolt fastening.
Catch-all support frame 2 is fixed through bolt and low-pressure side partition, and catch-all is fixed on switch support frame, by total
Switch it is suitable for reading connect with main bus-bar, the connection of the transformer low voltage side terminal of lower mouth and transformer room, forming circuit.
Low-pressure side partition is fastenedly connected multiple support frame a15 with tapping screw, and four interior spiral shells are produced on each support frame a
Line mounting hole, each support frame a pass through internal screw thread mounting hole and bolt and are fastenedly connected with breaker, the breaker and adapter
