Abstract

The utility model discloses a kind of railway locomotive universal novel resistance device, it is characterized in that: comprise the base be arranged on transformer, and be arranged at base resistor box, wherein, described base is made up of the adjusting part of direction, all around adjustable distance.The resistance that conventional traction transformer is paid in the RC absorber on limit by the utility model is independent, utilize the hole for hoist in existing traction voltage transformation to carry out installation to fix, under identical natural draft heat radiation operating mode, obviously improve resistive dissipation, open locomotive protective door and can carry out Inspection and maintenance to resistance device, very convenient when changing after damage.

Description

A kind of railway locomotive universal novel resistance device
Technical field
The utility model relates to railway electric locomotive capacitance resistance ware, specifically a kind of resistance device paid for railway SS4G traction transformer of electric locomotive in the winding capacitance resistance ware of limit.
Background technology
SS4G traction transformer of electric locomotive is paid on the winding of limit and is provided with RC absorber, for absorbing atmospheric over-voltage, switching overvoltage and harmonic current, usual RC absorber is arranged in PFC switch cubicle, the resistance of RC absorber is arranged in the top of PFC switch cubicle, resistance from locomotive roof distance within 10cm, therefore, when unavoidably causing current check and safeguard, be awkward, and under natural draft heat radiation operating mode, resistive dissipation is poor, and power loss is excessive burns rear replacing inconvenience, keeps in repair consuming time longer.Due to the restriction in locomotive space, in SS4G electric locomotive transformation RC absorber during resistance without suitable installation site, traction transformer superjacent air space can only be utilized.Traction transformer when installing additional, can only utilize the hole for hoist of traction transformer, but hole for hoist size is inconsistent.
Summary of the invention
Based on the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of use for electric locomotive universal novel resistance device, pays resistance in the winding capacitance resistance ware of limit in order to replace conventional traction transformer, to improve resistive dissipation, and convenient to check and maintenance.
For achieving the above object, technical solution adopted in the utility model is as follows:
A kind of railway locomotive universal novel resistance device, is characterized in that: comprise the base be arranged on transformer, and is arranged at the resistor box on base.Wherein, described base is made up of the adjusting part of direction, all around adjustable distance, has met the change of transformer hole for hoist.
Preferably, described front and back adjusting part comprises left longeron assembly and right vertical beam, and described left longeron assembly comprises left longeron A, and with the left longeron B that left longeron A slide anteroposterior connects; Described left and right adjusting assembly comprises front beam assembly and rear cross beam assembly, described front beam assembly comprise front beam A and with its front beam B be connected that horizontally slips, the rear cross beam B that described rear cross beam assembly comprises rear cross beam A and is connected with its slide anteroposterior.Described left longeron A is fixedly connected with front beam A, and described left longeron B is fixedly connected with rear cross beam A, and described right vertical beam two ends are individually fixed on front beam A and rear cross beam A.
By technique scheme, the beneficial effects of the utility model are:
1, the resistance paid in the RC absorber on limit by conventional traction transformer of the utility model is independent, utilizes the space on traction transformer to install.This resistance device install after from locomotive roof 25cm, under identical natural draft heat radiation operating mode, obviously improve resistive dissipation, opening locomotive protective door can carry out Inspection and maintenance to resistance device, and it is very convenient to carry out after damage changing;
2, the utility model can utilize the hole for hoist in existing traction voltage transformation to be fixed, and realizes flexible by base of the present utility model, easy for installation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 end view.
Embodiment
Below in conjunction with specific embodiment, structure of the present utility model, principle are elaborated.
As shown in Figure 1, a kind of railway locomotive universal novel resistance device, comprises the base be arranged on transformer, and be arranged at base resistor box 1, base is made up of the adjusting part of direction, all around adjustable distance.
Wherein, front and back adjusting part comprises left longeron assembly and right vertical beam 2, and left longeron assembly comprises left longeron 3-1, and with the left longeron 3-2 that left longeron 3-1 slide anteroposterior connects, and the adjustment of longitudinal installation dimension is realized by left longeron 3-2;
Left and right adjusting assembly comprises front beam assembly and rear cross beam assembly, front beam assembly comprise front beam 4-1 and with its front beam 4-2 be connected that horizontally slips, the rear cross beam 5-2 that rear cross beam assembly comprises rear cross beam 5-1 and is connected with its slide anteroposterior, realizes the adjustment of horizontal installation dimension.
Left longeron 3-1 is fixedly connected with front beam 4-1 with bolt through connector, and left longeron 3-2 is fixedly connected with rear cross beam 5-1 with bolt through connector, and right vertical beam 2 two ends are individually fixed on front beam 4-2 and rear cross beam 5-2 through connector and bolt.
