Abstract
The utility model relates to a split type motor soft starter. The split type motor soft starter comprises a first starter casing, a control circuit module, a power trigger circuit module, a power device module and wiring terminals and further comprises a second starter casing, wherein the power device module and the wiring terminals are mounted on the first starter casing, the control circuit module is in electrical connection with the power trigger circuit module, the power device module and the wiring terminals in order, and the control circuit module and the power trigger circuit module are mounted in the second starter casing. According to the split type motor soft starter, the control circuit module and the power trigger circuit module are effectively separated from the power device module, so loop current interference of the power device module onto the control circuit module and the power trigger circuit module is avoided, and related loss is reduced when the power device module is in fault. The split type motor soft starter has advantages of small volume, flexible and convenient maintenance and easy mounting and debugging.
Description
Technical field
The utility model relates to the starting device of motor technical field, relates in particular to a kind of split type motor soft initiator.
Background technology
Motor soft starter is that the soft start of a kind of current collection machine, soft stop, light-load energy saving and multi-protective function are in the motor control assembly of one.Motor soft starter generally comprises and starts shell and be arranged on control circuit module, power trigger circuit module, power device module and the binding post that starts in the shell, and control circuit module, power trigger circuit module, power device module and binding post are electrically connected in turn.Wherein, the two ends of binding post extend to the startup housing exterior from starting in the shell respectively, are used for being electrically connected power module and motor.
In the prior art, motor soft starter is installed in control circuit module, power trigger circuit module, power device module and binding post in the same startup shell, and in use control circuit module and power trigger circuit module very easily are subject to the impact of power device module.Such as the regular impact that is subject to loop current in the power device module, easily increase the failure rate of control circuit module and power trigger circuit module; And for example, the breakdown fault if power device module is short-circuited because control circuit module and power trigger circuit module and power device module distance are little, also can cause the burning of control circuit module and power trigger circuit module or damage, makes and loses progressive the increasing.And motor soft starter adopts integrated mounting structure to make the bulky of motor soft starter, and the space that takies when mounted also increases.
Summary of the invention
Technical problem to be solved in the utility model is to exist the problem that each circuit module influences each other to each other, failure rate is high for existing motor soft starter integrated mounting structure, and the split type motor soft initiator of a kind of control circuit module and power trigger circuit module and power device module effective separation is provided.
For addressing the above problem, the technical solution of the utility model is:
A kind of split type motor soft initiator, comprise the first starter shell, control circuit module, power trigger circuit module, power device module and binding post, described power device module and binding post are installed on the first starter shell, described control circuit module is electrically connected with power trigger circuit module, power device module and binding post successively, described soft initiator also comprises the second starter shell, and described control circuit module and power trigger circuit module are installed in the second starter shell.
Preferably, be respectively equipped with the RS485 interface on described power trigger circuit module and the power device module, power trigger circuit module and power device module are electrically connected by the RS485 interface.
Be compared to prior art, split type motor soft initiator of the present utility model is with control circuit module and power trigger circuit module and power device module effective separation, avoided control circuit module and power trigger circuit module to be subjected to the interference of power device module loop current, when the power device module fault, reduced related loss.Split type mounting structure has that volume is little, maintenance is flexible, the easy characteristics of adjustment and installation.
Description of drawings
Fig. 1 is the structural representation of the split type motor soft initiator of the utility model.
Embodiment
Further describe the utility model below in conjunction with drawings and Examples, but protection range of the present utility model is not limited to this.
With reference to Fig. 1, split type motor soft initiator of the present utility model comprises the first starter shell 1, the second starter shell 2, control circuit module 3, power trigger circuit module 4, RS485 interface 5, binding post 6 and power device module 7.In described the first starter shell 1 power device module 7 and binding post 6 are installed, the two ends of binding post 6 extend to the first starter shell 1 outside from the first starter shell 1 inside respectively, are used for being electrically connected power module and motor.In described the second starter shell 2 control circuit module 3 and power trigger circuit module 4 are installed, described control circuit module 3, power trigger circuit module 4, power device module 7 and binding post 6 are electrically connected in turn.Be respectively equipped with RS485 interface 5 on described power trigger circuit module 4 and the power device module 7, power trigger circuit module 4 and power device module 7 are electrically connected by the RS485 interface.
When using and split type motor soft initiator is installed, the first starter shell 1 is installed in the electrical control cabinet, make the two ends of binding post 6 connect respectively power source module and motor, the outside or farther electrical control that the second starter shell 2 is installed in the electrical control cabinet is indoor.The first starter shell 1 internal circuit and the second starter shell 2 internal circuits communicate by the RS485 interface 5 on power trigger circuit module 4 and the power device module 7, the first starter shell 1 also can link to each other with other host computer by the RS485 interface 5 on the power device module 7, in order to finish debugging or the control of the first starter shell 1 internal circuit.When repair and maintenance, only need respectively the first starter shell 1 internal circuit and the second starter shell 2 internal circuits to be overhauled respectively, as with normal the second starter shell 2 internal circuits of debugging a plurality of the first starter shell 1 internal circuits being carried out debugging and maintenance etc., reduced the complexity of repair and maintenance.If the first starter shell 1 internal circuit failure, because the first starter shell 1 internal circuit and the second starter shell 2 internal circuit separation distances are far away, basically can not impact the second starter shell 2 internal circuits, therefore, changing the first starter shell 1 internal circuit gets final product, need not the whole series and heavily change, reduced maintenance cost.
