Abstract
The invention relates to a star triangular output device with a low pressure drawer-type switch cabinet one-time contact, which comprises base pin cases, base pins and a guide rail, wherein each base pin case comprises a front part and a back part, an interlayer and bosses are arranged in each base pin case, base pins are provided with shoulder-shaped steps, the base pins are clamped in each base pin case, the shoulder-shaped steps are clamped between the front boss and the back boss of each base pin case to achieve the purpose of positioning the base pin, the lower part of each base pin case is provided with a sliding chute, the base pin cases can pass through the sliding chute and slide along an upper guide plate of the guide strip, the guide strip is fixedly connected with a drawer, and when the base pin cases slide to drive the base pin to breadthwise move relative to the drawer, the dividing and combining movement of a moving contact and a static contact is realized; each base pin case is separated into an upper chamber and a lower chamber by the interlayer, the base pins are respectively arranged in the upper chamber and the lower chamber of the same base pin case, and are driven by the base pin case to move forwards or backwards, and the synchronized motion of a plurality of groups of base pins is realized.
Description
Technical field
The present invention relates to a kind of low pressure drawer-type switch cabinet one-time contact star triangular output device in low-voltage complete switch equipment and the control appliance, belong to the low-voltage electrical apparatus field.
Background technology
In the low-tension switch cabinet distribution system in the market; Generally adopt star triangle reduced voltage starting; Because the stator winding for normal operation is the squirrel-cage asynchronous motor of delta connection,, treat to be connected into triangle again after starting finishes if when starting, stator winding is connected into star; Just can reduce starting current, alleviate its impact electrical network.The prior art mesolow drawer type star triangle reduced voltage starting way of output adopts is the one-in-and-two-out output of pegging graft, and promptly the moving pin of one group of inlet wire of fixing assembling, two groups of moving pins of outlets match with fixed contact on drawer, and every group of inlet wire or outlet pin all must dispose the pin box separately; The pin box is fixed on the drawer body again; Realize that several groups of moving pins connect simultaneously or separate, need to drive whole drawer body and move that operating process is wasted time and energy; Mechanism is easy to wear, causes system unstable.
Summary of the invention
Technical problem to be solved by this invention is; Provide a kind of simple in structure, laborsaving, fltting speed is fast; Accurate positioning; The low pressure drawer-type switch cabinet one-time contact star triangular output device that anti-error performance is good is not moving under the situation of drawer body, directly realizes deciliter action of turnover line pin and fixed contact.
The technical scheme that solves its technical problem employing is: design a kind of low pressure drawer-type switch cabinet one-time contact star triangular output device, comprise pin box, pin, guide rail; The pin box is made up of front and back two parts, has interlayer in the box, and boss is set; Have shoulder shape step on the pin, pin is installed in the pin box, and its shoulder shape step is stuck between the pin box boss of front and back, to reach the purpose of pin location; Pin box bottom is provided with chute, and the pin box can be through chute along the slippage of guide rail upper guide plate; Guide rail is fixedly connected on the drawer, drives pin during the slippage of pin box and moves forward and backward with respect to drawer, has realized deciliter action of moving contact and fixed contact.The pin box is separated into up and down two Room by interlayer, and it is two indoor that pin is distributed in same pin box up and down, advances simultaneously or retreats by the pin tape is moving, has realized being synchronized with the movement of several groups of pins.
The present invention one group of inlet wire pin, two groups of outlet pins when work are sub-packed in inlet wire pin box and the outlet pin pin box; The advanced in unison that realizes all pin boxes through propulsion device of primary contact with retreat; Mechanism element quantity is few, operation easily, noiselessness produces when carrying out deciliter action; And parts adopt recyclable material to process, and can reuse behind the product rejection, can not produce the solid waste of contaminated environment.
