Description
Technical field
The present invention relates to a kind of large current outlet box structure that is used as low-voltage, high-current wind driven generator principal outlet box.
Background technology
The motor outlet box is one of indispensable parts in the electric machine structure.The space structure of outlet box must guarantee that enough big electrical distance is arranged between the threephase cable joint, and cable joint connects with busbar has enough big track wrench space close with enough low conduction electricity, and busbar self fixed form is solid reliable.
The low-voltage, high-current motor master outlet box that present China is produced utilizes copper busbar to be bent into cable usually and connects busbar, and is fixed on the insulated terminal of hybrid resin cast.The insulated terminal insulation property are reliable, and electrical insulation properties is good, and foot can guarantee the electrical distance that motor needs; But the fixing main cast bolt wherein that relies between itself and busbar, the support is along with certain vibration takes place in the operation of motor easily; Though the copper busbar bending is convenient, many turnover cables are often arranged in the main outlet box of low-voltage, high-current motor, the weight of cable is easy to cause the distortion of copper busbar curvature, and cable can be swung along with the motor operation.For the wind power system of odd maintenance, high reliability request, above conventional low large current outlet box is inapplicable gradually.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art; A kind of simple in structure, safe and reliable big electric current wind-powered electricity generation outlet box structure is provided; This outlet box structure is used as the main outlet box of low-voltage, high-current wind-driven generator, with reliability and the fail safe of guaranteeing that low-voltage, high-current wind power generation machine circuit connects.
According to technical scheme provided by the invention: big electric current wind-powered electricity generation outlet box structure; It is characterized in that: comprise high pressure lightning protection chamber and low-voltage, high-current chamber; Said high pressure lightning protection is used to install the high pressure lightning protection facility separately in the chamber; Inner top, said low-voltage, high-current chamber is equipped with insulative support frame, on insulative support frame, is installed with the busbar of a plurality of equidistant distributions.
As further improvement of the present invention, said insulative support frame is a rectangle structure, and its two ends are through being bolted on the outlet cassette holder.
As further improvement of the present invention, said insulative support frame adopts expoxy glass to process.
As further improvement of the present invention, said busbar is bent into the U-shaped structure, and is middle through the dividing plate reinforcement of weld after the bending.
As further improvement of the present invention, busbar adopts soft red copper to process.
The present invention compared with prior art, advantage is: the present invention is simple in structure, compact, the high and low pressure service area is well defined, action effect is obvious; Insulative support frame adopts expoxy glass to process, and the expoxy glass low price, draw materials and handling ease, and expoxy glass itself is high pressure resistant material that voltage withstand class is high; Said busbar is bent into the U type, and the dividing plate reinforcement of weld is used in the centre after the bending, guarantees that busbar itself has enough resistance to deformation intensity, and the dual-side of U type busbar has enough spaces to allow cable joint to be connected with it.
Description of drawings
Fig. 1 is the overall structure sketch map of the embodiment of the invention.
Fig. 2 is a structure left view of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1; Big electric current wind-powered electricity generation outlet box structure among the embodiment comprises high pressure lightning protection chamber 1 and low-voltage, high-current chamber 2; Be used to install the high pressure lightning protection facility separately in the said high pressure lightning protection chamber 1; 2 inner tops, said low-voltage, high-current chamber are equipped with insulative support frame 3, on insulative support frame 3, are installed with the busbar 4 of a plurality of equidistant distributions.
Outlet box structure of the present invention is according to the operating voltage grade; Outlet box is divided into the high pressure lightning protection chamber 1 and the low-voltage, high-current chamber 2 that is used for the stube cable joint that is used to hold installation high pressure lightning protection facility; Between high pressure lightning protection chamber 1 and the low-voltage, high-current chamber 2 clear and definite area boundary is arranged; The high and low pressure service area is well defined, and makes that on the one hand high quick thunder resisting equipment and large-current electric cable are unaffected each other, makes the technical staff on the other hand when Installation and Debugging; Can take concrete different security measure respectively to the high and low pressure service area, to prevent misoperation.
Like Fig. 1, shown in Figure 2; Low-voltage, high-current chamber 2 is places that the low-voltage, high-current cable joint connects; Said insulative support frame 3 is a rectangle structure; Insulative support frame 3 is lain across above 2 inside, low-voltage, high-current chamber, and insulative support frame 3 two ends are bolted on the outlet cassette holder through four, and structure is very firm; It is high that said insulative support frame 3 itself has certain length and width, reserved enough spaces and supplied busbar 4 to be connected with it with cable joint.The preferred expoxy glasss that adopt of insulative support frame 3 among the present invention are processed, and the expoxy glass low price, draw materials and handling ease, have certain resistance to compression, resistance to tension; And expoxy glass itself is high pressure resistant material; Voltage withstand class is high, and high temperature resistance we can say to reach the purpose of achieving many things at one stroke.
As shown in Figure 1, said busbar 4 is bent into the U-shaped structure, and is middle through the dividing plate reinforcement of weld, so that it has enough non-deformabilities after the bending; Busbar 4 adopts soft red copper to process.Busbar 4 tops and insulative support frame 3 link together through two bolt, compare traditional single bolt and connect, and structure is more firm; It is in a row fixing successively that busbar 4 has enough spaces to hold many strands of cable joints in the depth direction of outlet box, thereby it is too much to have solved low voltage large current outlet box cable joint, the difficult point that the space is difficult to arrange.
Generally speaking, big electric current wind-powered electricity generation outlet box compact conformation of the present invention, rationally, action effect is obvious, can solve a difficult problem in many ways with achieving many things at one stroke, be fit to be used in have that zero dimension is protected, in the wind power system of high reliability request.
The foregoing description only is a preferred implementation of the present invention, and the present invention is not limited to above embodiment.Other improvement and variation that those skilled in the art directly derive under the prerequisite that does not break away from spirit of the present invention and design or associate all should be thought to be included within protection scope of the present invention.
