Abstract
A low-voltage balance outgoing line method of a triangular transformer, connect the low-voltage head end lead wire of A phase and C phase to the leading-out terminal of head end of the low-voltage coil of B phase directly, the zero line lead wire is drawn out from the head end of the low-voltage coil of B phase directly; due to the symmetry of the triangular transformer, the lengths of the leading wires at the head ends of the A phase and the C phase are the same, the resistances of the leading wires at the head ends of the A phase and the C phase are equal, the leading wire at the head end of the B phase is not provided with the leading wire, and the resistance is regarded as zero; the tail ends of the A phase and the C phase are directly led out, the resistance of the tail ends of the A phase and the C phase is regarded as zero, the length of a tail end lead of the B phase coil is adjusted to be the same as that of a head end lead of the A phase or the C phase, and the tail end lead resistance of the B phase is the same as that of the head end lead of the A phase and the C phase; therefore, each phase of loop only has one lead busbar resistor, and the problem of unbalanced low-voltage lead resistor of the triangular transformer is fundamentally solved.
Description
Technical field:
The low pressure that the present invention relates to a kind of transformer goes out line method, particularly the method for the low-pressure balance outlet of triangularity depressor.
Background technology:
The low pressure outlet of existing triangularity depressor, it connects based on the symmetry of three-phase head end busbar, and its resistance all equates; A and C be directly outlet mutually, because B is in vertex of a triangle, its outlet busbar is longer, its resistance greater than A and C mutually go out line resistance, must cause three-phase to go out the imbalance of line resistance like this.
Summary of the invention:
The objective of the invention is to: the low-pressure balance that proposes a kind of triangularity depressor goes out line method.
Implementation method of the present invention is: go between A with C low pressure head end mutually mutually and directly receive the head end leading-out terminal of B phase low-voltage coil, the zero line lead-in wire is directly drawn from the head end of B phase low-voltage coil; Because the symmetry of triangularity depressor, the head end wire length of A phase and C phase is identical, and their head end lead resistance equates that the head end of B phase does not have lead-in wire, and its resistance is regarded as zero; A phase and C terminal directly outlet mutually, its resistance is regarded as zero, and the end leads length of regulating B phase low-voltage coil is identical with the head end wire length of A phase or C phase, and then the end leads resistance of B phase is identical with the head end lead resistance of C phase mutually with A; Every like this phase loop has only a lead resistance, fundamentally solves the problem of triangularity depressor low-voltage lead resistance unbalance.
The invention has the advantages that:, reach triangularity depressor low-voltage lead resistance balance with minimum connection busbar.
Description of drawings
The low pressure outlet schematic diagram of the existing triangularity depressor of Fig. 1
Fig. 2 low-pressure balance goes out the schematic diagram of line method
Among Fig. 1: R0 is A phase, B are connected busbar mutually with the head end of C phase a resistance; R1 is the resistance of B phase outlet busbar; C0 is a low-voltage coil; A, B and C three-phase go out terminal, and the 0th, the zero line outlet.
Among Fig. 2: R0 is the head end of the A phase head end resistance that connects busbar, the C phase resistance that connects busbar and the B resistance of outlet busbar mutually; C0 is a low-voltage coil; A, B and C three-phase outlet terminal, the 0th, the zero line outlet.
Embodiment
Accompanying drawing discloses method of the present invention without limitation, below in conjunction with legend the present invention is further specified.
Be the low pressure outlet schematic diagram of existing triangularity depressor among Fig. 1, it connects based on the symmetry of three-phase head end, thus this three be connected busbar resistance all be R0; A and C directly outlet mutually go out line resistance and can be considered zero; Because B is on the summit of triangularity depressor, its outlet busbar is longer, and its resistance is R1, must cause three-phase to go out the imbalance of line resistance like this.
Fig. 2 is the low-pressure balance outlet schematic diagram that the present invention proposes; It removes the lead-in wire of the head end of B phase; The head end of A and C is connected the direct tandem of busbar to the outlet terminal of B phase, is equivalent to remove the resistance that B phase head end connects busbar, and zero line is directly drawn on the outlet terminal of B phase; If the resistance of B phase outlet busbar is R0, so just can accomplish that triangularity depressor three-phase goes out the balance of line resistance.
