Abstract
The invention relates to an operation mechanism of an electric switch cabinet. The operation mechanism comprises a spring support, a spindle, a switching off and switching on spring and a switching off acceleration spring. A first spring seat and a second spring seat are respectively installed on the spring support, and a first rotating shaft and a second rotating shaft are respectively arranged on the spindle. One end of the switching off and switching on spring is hinged on the first spring seat, and the other end of the switching off and switching on spring is supported on the first rotating shaft. One end of the switching off acceleration spring is hinged on the second spring seat, and the other end of the switching off acceleration spring is supported on the second rotating shaft. The operation mechanism adopts a double-spring mechanism. In the switching on process, compression and release energy of only one spring (the switching off and switching on spring) is used, and simultaneously the other spring (the switching off acceleration spring) stores energy for the switching off process. In the switching off process, compression and release energy of one spring (the switching off acceleration spring) is used, and simultaneously the other spring (the switching off and switching on spring) stores energy, so that switching off speed is greatly improved. The operation mechanism solves the problem that the operation mechanism of a full-closed full-insulated loop network switch cabinet is poor in operation and unsmooth in use.
Description
Technical field
The present invention relates to a kind of operating mechanism of cabinet, belong to the cabinet technical field.
Background technology
The operating mechanism majority that the totally-enclosed all insulation loop-network switch cabinet of existing HXGN adopts is single spring mechanism, there are problems in operating mechanism, be easy to generate phenomenons such as operation is not in place, bite, the speed of divide-shut brake is not enough, and the synchronism of the contact contact of gas tank inside is not good.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of operating mechanism of cabinet of dual spring is provided, phenomenons such as the operation that is intended to avoid operating mechanism to occur is not in place, bite improve the reaction speed of switch divide-shut brake and the synchronism of inside contact.
Purpose of the present invention is achieved through the following technical solutions:
The operating mechanism of cabinet, characteristics are: comprise spring fastening, main shaft, divide-shut brake spring and separating brake acceleration spring, be separately installed with first spring base and second spring base on the spring fastening, be respectively equipped with first rotating shaft and second rotating shaft on the main shaft, one end of divide-shut brake spring is articulated on first spring base, the other end of divide-shut brake spring is supported in first rotating shaft, and an end of separating brake acceleration spring is articulated on second spring base, and the other end of separating brake acceleration spring is supported in second rotating shaft.
Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:
The present invention adopts dual spring mechanism, the compression of when closing a floodgate, only using a spring (divide-shut brake spring) wherein with release energy, another root spring (separating brake acceleration spring) energy storage is that separating brake is prepared simultaneously; The compression of when separating brake, using a spring (separating brake acceleration spring) with release energy, another root spring (divide-shut brake spring) energy storage has improved opening velocity greatly simultaneously.Problems such as the operation of avoiding totally-enclosed all insulation loop-network switch cabinet operating mechanism to occur is not in place, bite improve the reaction speed of switch divide-shut brake and the synchronism of inside contact.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: the schematic diagram of operating mechanism gate-dividing state of the present invention;
Fig. 2: the schematic diagram of operating mechanism "on" position of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, the operating mechanism of cabinet, comprise spring fastening 1, main shaft 2, divide-shut brake spring 3 and separating brake acceleration spring 4, be separately installed with first spring base and second spring base on the spring fastening 1, be respectively equipped with first rotating shaft and second rotating shaft on the main shaft 2, one end of divide-shut brake spring 3 is articulated on first spring base, the other end of divide-shut brake spring 3 is supported in first rotating shaft, one end of separating brake acceleration spring 4 is articulated on second spring base, and the other end of separating brake acceleration spring 4 is supported in second rotating shaft.
Spring fastening 1 is non-moving component, and main shaft 2 circular motion drive the motion of main contact up time and close a floodgate inverse time motion separating brake.Divide-shut brake spring 3 be spring compressed earlier release energy behind the dead point drive the switch main contact do up time or the circular motion of inverse time realize switch deciliter.Separating brake acceleration spring 4 be when closing a floodgate be the tripping spring energy storage during at separating brake the separating brake acceleration spring release can be with the function that realizes that separating brake accelerates.
Operating mechanism adopts dual spring mechanism, as Fig. 2, the compression of when closing a floodgate, only using a spring (divide-shut brake spring 3) wherein with release energy, another root spring (separating brake acceleration spring 4) energy storage is that separating brake is prepared simultaneously; As Fig. 1, the compression of when separating brake, using a spring (separating brake acceleration spring 4) with release energy, another root spring (divide-shut brake spring 3) energy storage has improved opening velocity greatly simultaneously.
The rack piece surface adopts plating nickel-phosphorus alloy to handle, and has improved the antiseptic power of parts greatly, guarantees the uniform stabilizing quality of mechanical performance.
In sum, the present invention designs uniqueness, novel structure, efficiently solves problems such as the operation that totally-enclosed all insulation loop-network switch cabinet operating mechanism occurs is not in place, bite, improves the synchronism of on-load switch inside contact contact.
What need understand is: the above only is preferred implementation of the present invention; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
