Description
Technical field
The utility model relates to a kind of shell frequency converter of moulding, and is specifically related to a kind of frequency converter terminal board array structure.
Background technology
Frequency converter is application of frequency conversion technology and microelectric technique, changes the electric control appliance of machine operation supply frequency.To be the on-off action that utilizes power semiconductor device be transformed to the electric energy control device of another frequency with power frequency supply to its principle, can realize to AC induction motor soft start, frequency control, raising running accuracy, change power factor, overcurrent/overvoltage/overload protection etc.The existing binding post of moulding the shell frequency converter is divided into:
P+: dc bus is anodal
P-: dc bus negative pole
PB: brake resistance
E: the earth
R, S, T: input power supply (three-phase)
U, V, W: the output of frequency converter three-phase
When single phase poaer supply used, because of having only the two-way input, so corresponding R, T were L1, L2, S terminal room.
General by following dual mode arrangement, a kind of is lower end inlet wire (R, S, T), lower end outlet (U, V, W); Another kind is a upper end inlet wire (R, S, T), lower end outlet (U, V, W).The cabinet of moulding the shell frequency converter is divided into base, mesochite and three parts of loam cake, and binding post is installed in the upper and lower side of mesochite, because client's demands of different; There are some that P+, P-and PB terminal also need be set; Therefore, when producing, need offer the demand that multiple kinds of molds could satisfy the user.
The utility model content
Be difficult to satisfy requirements of different users in order to overcome the existing distribution form of moulding the binding post of shell frequency converter; Need offer the deficiency of multiple kinds of molds; The utility model provides a kind of frequency converter terminal board array structure; This terminal board array structure reasonable Arrangement each terminal, only need to adopt the cabinet mesochite of same structure, just can satisfy user's requirement.
The technical scheme of the utility model is: a kind of frequency converter terminal board array structure comprises base; Base is provided with mesochite; The upper and lower end of mesochite is respectively equipped with mounting groove and following mounting groove, and last mounting groove correspondence is installed the binding post box, the corresponding lower connecting terminal box of installing of following mounting groove; Binding post in the upper connecting terminal box is 4; Be respectively the anodal P+ of dc bus, dc bus negative pole P-, brake resistance PB and the earth E; The binding post of lower connecting terminal box is 7, is respectively three-phase input power supply (R, S, T), the output of frequency converter three-phase (U, V, W) and the earth E.
The PCB circuit board is installed on the described mesochite, and the PCB circuit board is electrically connected with each binding post.
The utlity model has following beneficial effect: owing to take such scheme; Three-phase input power supply (R, S, T) and frequency converter three-phase output (U, V, W) all are arranged on the below of mesochite; And the anodal P+ of dc bus, dc bus negative pole P-, brake resistance PB and the earth E are arranged on the top of mesochite; When not using P+, P-, PB and E terminal, can the last mounting groove shutoff of top be realized the mode of connection that advance down to go out down.During the mode of connection that goes out on going out down or advancing down when needs are enterprising; Change the mode of connection on the PCB circuit board, utilize 4 binding posts in the upper connecting terminal box to import power supply (R, S, T) and the earth E or the output of frequency converter three-phase (U, V, W) and the earth E as three-phase.This terminal board array structure reasonable Arrangement each terminal, only need to adopt same Mould Machining to go out the cabinet mesochite of same structure, just can satisfy user's requirement, cost is low, and is applied widely.
Description of drawings
Accompanying drawing 1 is the perspective view of the utility model.
1-base among the figure, 2-mesochite, the last mounting groove of 3-, mounting groove under the 4-; 5-upper connecting terminal box, 6-lower connecting terminal box, 7-PCB circuit board; P+: dc bus is anodal, P-: dc bus negative pole, PB: brake resistance; E: the earth, R, S, T: input power supply (three-phase), U, V, W: the output of frequency converter three-phase.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1; A kind of frequency converter terminal board array structure comprises base 1, and base 1 is provided with mesochite 2, and the upper and lower end of mesochite 2 is respectively equipped with mounting groove 3 and following mounting groove 4; Last mounting groove 3 correspondences are installed binding post box 5, the following mounting groove 4 corresponding lower connecting terminal boxes 6 of installing; Binding post in the upper connecting terminal box 5 is 4; Be respectively the anodal P+ of dc bus, dc bus negative pole P-, brake resistance PB and the earth E; The binding post of lower connecting terminal box 6 is 7, is respectively three-phase input power supply (R, S, T), the output of frequency converter three-phase (U, V, W) and the earth E.Owing to take technique scheme; Three-phase input power supply (R, S, T) and frequency converter three-phase output (U, V, W) all are arranged on the below of mesochite 2; And the anodal P+ of dc bus, dc bus negative pole P-, brake resistance PB and the earth E are arranged on the top of mesochite 2; When not using P+, P-, PB and E terminal, can last mounting groove 3 shutoff of top be realized the mode of connection that advance down to go out down.When needs are enterprising go out down or advance down go out down the mode of connection time; Change the mode of connection on the PCB circuit board, utilize 4 binding posts in the upper connecting terminal box 5 to import power supply (R, S, T) and the earth E or the output of frequency converter three-phase (U, V, W) and the earth E as three-phase.When importing as individual event, the terminal in the middle of three-phase being imported under the terminal hollow of power supply (R, S, T) uses the terminal on both sides get final product, promptly uses R and T terminal as importing power supply (being L1 and L2), and ground wire E is constant.This terminal board array structure reasonable Arrangement each terminal, only need to adopt same Mould Machining to go out the cabinet mesochite 2 of same structure, just can satisfy user's requirement, cost is low, and is applied widely.
