Abstract
The utility model discloses a soft starter relates to electrical components, concretely relates to soft starter wiring end structure. Including the casing, the casing front side is provided with the gate body and the little door body on the surface, down, and the gate body and xiao men side limit are through the connection casing of folding paper, the external surface mounting in gate has display and button, installs soft starter circuit component in the casing of the internal side in gate, the internal side of little door is fluted, has PTC binding post in the recess, casing front side bottom border is provided with signal input part able to programme and field bus communication wiring end, the border is provided with outer bypass contactor wiring end and signal relay able to programme wiring end on the little door body front side. The utility model provides a current soft starter housing face set up the wiring with inside and hold, need dismantle the casing during installation, operate inconvenient problem.
Description
Technical field
The utility model relates to electric elements, is specifically related to a kind of soft initiator terminal structure.
Background technology
Soft initiator is a kind of Electric Machine Control equipment integrating soft start, soft stop, light-load energy saving and multifunction protection.Realize starter motor level and smooth without impacting in whole start-up course, and the various parameters in start-up course can be regulated according to the characteristic of motor load, as cut-off current, start-up time etc.
Soft initiator is a kind of novel motor control assembly integrating electric machine soft starting, soft stop, light-load energy saving and multi-protective function, is called SoftStarter abroad.Soft initiator adopts three-phase anti-parallel thyristor as voltage regulator, is accessed between power supply and motor stator.This circuit is as three-phase thyristor bridge rectification circuit.When using soft initiator actuating motor, the output voltage of thyristor increases gradually, and motor accelerates gradually, until the full conducting of thyristor, motor is operated in the mechanical property of rated voltage, realizes smoothly starting, and reduces starting current, avoids starting overcurrent tripping.When motor reaches rated revolution, start-up course terminates, soft initiator replaces the thyristor of having finished the work from employing bypass contactor, rated voltage is provided for motor runs well, to reduce the thermal losses of thyristor, extend the useful life of soft initiator, improve its operating efficiency, make again electrical network avoid harmonic pollution.Soft initiator also provides soft stop function simultaneously, and soft stop is contrary with soft start-up process, and voltage reduces gradually, and revolution drops to zero gradually, avoids the torque shock ends that free parking causes.
Existing soft initiator surface of shell and inside arrange terminals, need to dismantle housing during installation, very inconvenient.
Summary of the invention
The utility model provides soft initiator, and the utility model solves existing soft initiator surface of shell and inside arranges terminals, needs to dismantle housing, the problem of inconvenient operation during installation.
For solving the problem, the utility model adopts following technical scheme: soft initiator, comprises housing, and housing front side surface is upper and lower is provided with gate body and wicket body, and gate body is connected housing with limit, wicket side by folding; Gate external surface is provided with display and button, is provided with soft initiator circuit element in the housing inside gate body; Fluted inside wicket body, there is PTC binding post in groove; On front side of housing, bottom sides is along being provided with programmable signal input and field bus communication terminals; On front side of wicket body, upper edge is provided with outer bypass contactor terminals and programmable signal relay wiring end.
The present utility model point is, is provided with gate body and wicket body, during maintenance, opens gate body, need not panel be dismantled.PTC binding post is arranged in groove in addition, is provided with wicket body outside groove, uses more safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Symbol description in figure: housing 1, installs baffle plate 2, PTC binding post 3, programmable signal input 4, field bus communication terminals 5, wicket body 6, button 7, display 8, gate body 9, outer bypass contactor terminals 10, programmable signal relay wiring end 11.
Embodiment
By best embodiment, the utility model is described in detail below
.
As shown in Figure 1, soft initiator, comprises housing 1, and housing 1 front side surface is upper and lower is provided with gate body 9 and wicket body 6, and gate body 9 is connected housing 1 with wicket body 6 side by folding; Gate body 9 outer surface is provided with display 8 and button 7, is provided with soft initiator circuit element in the housing 1 inside gate body 9; Fluted inside wicket body 6, there is PTC binding post 3 in groove; On front side of housing 1, bottom sides is along being provided with programmable signal input 4 and field bus communication terminals 5; On front side of wicket body 6, upper edge is provided with outer bypass contactor terminals 10 and programmable signal relay wiring end 11.
Housing 1 back side panel left and right limit connection baffle plate 2, installs baffle plate 2 and protrudes from side, install baffle plate 2 and housing 1 back side panel integrative-structure, installs on baffle plate 2 and arranges erection opening.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of amplifying out or variation be still among protection range of the present utility model.
Claims (2)
1. soft initiator, comprises housing, it is characterized in that, housing front side surface is upper and lower is provided with gate body and wicket body, and gate body is connected housing with limit, wicket side by folding; Gate external surface is provided with display and button, is provided with soft initiator circuit element in the housing inside gate body; Fluted inside wicket body, there is PTC binding post in groove; On front side of housing, bottom sides is along being provided with programmable signal input and field bus communication terminals; On front side of wicket body, upper edge is provided with outer bypass contactor terminals and programmable signal relay wiring end.
