The reversible control switch electrical equipment of one of control and protection switch electrical equipment (CPS) annex; It is the control apparatus of realizing motor commutation through two in the three phase mains of switching motor mutually; Be used with control and protection switch electrical equipment body; The operation control of motor be can well realize, telecommunication, far distance automatic controlling, function such as protection and signal alarm automatically comprised.
The reversible product of tradition adopts two reversible controls of the chain realization motor of product to use, and this kind main body is constant, a large amount of materials savings of structure of a reversible conversion equipment of series connection.
Complex structure, the technological requirement of the reversible conversion equipment design in the reversible control switch electrical equipment of part are higher, and the processing and manufacturing cost is bigger; The reversible conversion device structure design of part is very unreasonable, poor stability, and when the contact system temperature rise reached uniform temperature, performance can not get guaranteeing.These reduce cost for product, and it is many unfavorable that aspects such as the reliability of enhancing product performance, stability and life-span produce.
The utility model content
The purpose of the utility model is exactly the problems referred to above that exist in the prior art in order to solve, and provides a kind of modular reversible conversion equipment.
The purpose of the utility model realizes through following technical scheme:
The reversible conversion equipment of modular; Include reversible support; Be provided with cross arrangement lead-in line row and outlet row in the reversible support; Wherein: the output of said lead-in line row and outlet row's input is provided with the fixed contact of former and later two positions, and the working end of said fixed contact is provided with touches axle assemble, and the said axle assemble that touches is connected the output of assembly connection lead-in line row and outlet row's input through elasticity.
Further, the reversible conversion equipment of above-mentioned modular, wherein: the described axle assemble that touches includes the movable contact bridge; On the described movable contact bridge moving contact is installed; The working end of said moving contact is corresponding with the working end of fixed contact, simultaneously, touches axle assemble and under external force drives, can in support, move front and back; Realize former and later two final positions, realize the connection and the translation function of turnover line thus.
Further, the reversible conversion equipment of above-mentioned modular, wherein: described elasticity is connected assembly and includes spring base, described spring base with touch axle assemble and link to each other, be provided with elastic parts in the described spring base.
Again further, the reversible conversion equipment of above-mentioned modular, wherein: described elastic parts is the shell fragment assembly, or described elastic parts is a spring assembly.
The advantage of the utility model technical scheme is mainly reflected in: each parts are assemblied on the reversible support cleverly, and whole device is compact more, stable, reliable, but significantly reduces the fault of inverse conversion, has prolonged useful life.And, improved whole degree safe in utilization, be worthy to be popularized.
Description of drawings
The purpose of the utility model, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using the utility model technical scheme, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of the utility model requirement protection.In the middle of these accompanying drawings,
Fig. 1 is the organigram of the reversible conversion equipment of modular.
Embodiment
The reversible conversion equipment of modular as shown in Figure 1; Include reversible support 1; In reversible support 1, be provided with lead-in line row 2, its unusual part is: the utility model adopts two phase lead-in line row cross arrangement, and the output of lead-in line row is provided with the fixed contact of two positions.Corresponding final position, specifically, the output of lead-in line row 2 is provided with fixed contact 3, and for the ease of conduction, the working end of fixed contact 3 is provided with touches axle assemble.Simultaneously, this touches axle assemble and is connected the input that assembly is connected with connection row 4 through elasticity, and the output that connects row 4 is connected with outlet row 5.
With regard to the utility model one preferred implementation, consider the conversion of working smoothly, touch axle assemble and include movable contact bridge 6.Specifically, moving contact 7 is installed on the movable contact bridge 6, and the working end of contact is corresponding with the working end of fixed contact 3.
Further, for the ease of the smooth and easy work of each contact, elasticity is connected assembly and includes spring base 8, this spring base 8 with touch axle assemble and link to each other, be provided with elastic parts in the spring base 8.Specifically, the elastic parts of employing is the shell fragment assembly.Certainly, the elastic parts of employing is a spring assembly 9, and effect is better.When reality was used, spring base 8 material selection heat proof materials had stoped the heat that touches on the bridge to be transmitted to spring assembly 9, influence the assembly spring performance, have guaranteed the service behaviour of spring assembly 9.And each contact has been done excess of stroke design, has improved the reliability of contact in wearing and tearing, the back contact conducting of ablating.
Actual operating position in conjunction with the utility model; At least two phases of reversible support 1 inside; For example A, C are designed to two phases of mutual reversible switching mutually, and each busbar by two sections single-ended band fixed contacts 3 of quarter-phase circuit is formed through the moving contact conducting of touching axle assemble.And the end that two phase busbars have the contact is fixed in the corresponding slot mutually of charged draw last breath edge and heat insulating function support, and an other phase busbar directly matrix location notch below reversible support 1 passes.Simultaneously, the inner set guide groove of reversible support 1 with touch axle assemble and cooperate reciprocating motion in the certain stroke on reversible support 1 guide rail.Move to former and later two final positions through contact supporting, drive movable contact bridge 6 conducting A, C two groups of fixed contacts of former and later two different final positions mutually, realize that A, C phase inlet wire line connect and the phase place switching, thus the conversion of control motor direction of rotation.
Can find out that through above-mentioned character express behind employing the utility model, each parts are assemblied on the reversible support cleverly, whole device is compact more, stable, reliable, but significantly reduces the fault of inverse conversion, has prolonged useful life.And, improved whole degree safe in utilization, be worthy to be popularized.
