Description
Technical field
The utility model relates to a kind of low pressure pull-out type switchgear assembly that has.
Background technology
Because traditional cabinet body frame adopts the connected mode of screw screw etc., and need to install the bus device etc. of a plurality of dust panels, power supply control in the low-voltage cabinet, therefore need a lot of screw, bringing to the manufacturing needs inconvenience.
The low tension switch drawout cubicle comprises a plurality of mutual isolation that are separated into by dust panel, non-interfering trimming function unit.At present, the low tension switch drawout cubicle feeds out every 10 loops is installed at most, in actual use, often needs the low tension switch drawout cubicle of separate unit greater than 10 element loops.The height of a general low pressure pull-out type switchgear assembly is equivalent to the height of which floor building, in the epoch of current soil anxiety, the overall dimensions of low low pressure pull-out type switchgear assembly is difficult for increasing, and because the qualification of element loop embedding structure and function, the height modulus of each element loop is malleable not also, the low tension switch drawout cubicle of original size is had greater than 10 element loops, and this element loop is separate, do not disturb mutually, and can independently finish the open position of trimming function element loop, the experiment position, the conversion of three positions of on-position, this becomes the current technical problem that needs to be resolved hurrily.
Bus clip is the electrical accessorie commonly used that power control part divides in the low-voltage complete equipment for power transmission and distribution.Traditional low-voltage distribution cabinet, a kind of bus-bar clamp device is a whole accessory, promptly the monoblock bus clip that is made into a plurality of moulding according to the length and the width of bus is offered many buses according to the size shape that bus is installed on the monoblock bus clip grooves is installed, and bus embeds in the groove.The cost of manufacture height of above-mentioned bus clip equipment, complex process, the installation of equipment, dismounting and carrying inconvenience, and because the bus surface is wrapped in the bus clip fully, the bus radiating effect is poor.Another kind of bus clip comprises the last fixture block and the following fixture block of paired cooperation, clamping in opposite directions, and last fixture block is respectively equipped with the groove corresponding with shape of generatrix with following fixture block, and the both sides of groove are cell walls, and fixture block passes through bolt up and down; Continuous increase along with electricity consumption current strength, the deficiency of this kind bus clip displays gradually, this be because, high frequency can take place owing to the effect of electric current and laterally tremble in metallic bus bar when work, thereby cell wall is produced lateral impact forces, the metallic bus bar in the close outside can to corresponding cell wall and around the position produce outside stretching torsion, because this outside cell wall is an idol relatively, few with the connection relationship at position on every side, lack adjacent regions and limit its outside distortion, after this position is subjected to outside impulsive force, can produce distortion by a relatively large margin, ruptured in this position, the cell wall of outermost side will be shifted, come off, the bus of outermost side will lose constraint and jump out groove, cause potential safety hazard, so, strengthen cell wall and bear powerful impulsive force, be the problem that presses for solution.
Low-voltage distribution cabinet, general compact conformation, narrow space, the above-mentioned one bus clip and the bus clip of fixture block structure up and down want in narrow space, insert the copper bar bus in bus clip, and construction is very difficult.
