Abstract
The utility model relates to a functions combined current converter group, which is suitable to be used for power distribution handcart type switchgear. The current converter group mainly comprises a current transformer A with a contact box, and a bearing type contact box B, the installation and the disassembly are very convenient, the positioning is accurate, the current transformer can be directly replaced in the handcart room, the static contact position not need to be readjusted. Compared with the prior art, the utility model has the advantages of convenient installation and disassembly, accurate positioning of the contact, good interchangeability of the handcart, no restriction to the current (can be low to 20/5), etc.
Description
Technical field:
The utility model relates to a kind of function combinations formula power pack group, is suitable for the distribution handcart switch cabinet and uses.
Background technology:
Current transformer in the handcart switch cabinet and contact box can be discrete, also can be integral combined.General band contact box current transformer is split when replacing to get off, change new band contact box current transformer after, contact position is difficult to guarantee original accurate position.Therefore the exchange poor performance of handcart is particularly on-the-spot in operation, in the absence of standard handcart adjustment, very bothers and inconvenience.Kind of a current transformer of installing and removing is previously arranged at present because the restriction of a structural winding single-turn type, can't be applied to when current ratio be 100/5 or occasion when following, so range of application is restricted.
Summary of the invention:
The purpose of this utility model provides a kind of function combinations formula power pack group, and it can overcome the deficiencies in the prior art.
The utility model is to realize like this, it mainly is made up of band contact box current transformer A and pedestal contact box B, band contact box current transformer A has current transformer 1, contact box 2, mounting flange 3, height shirt rim 4, preceding fixed contact 5, back fixed contact 6, location hole 7 and shirt rim group 8, pedestal contact box B has quiet Mume flower contact seat 9, location round pin 10, insulating shield 11, shirt rim 12, major loop terminal block 13 and mounting flange 14, wherein, contact box 2 front ends have mounting flange 3, the inner chamber of contact box 2 is conical, the inner chamber front end has shirt rim group 8, there is height shirt rim 4 at the rear portion of current transformer 1, the preceding fixed contact 5 and the back fixed contact 6 (winding terminal) of current transformer 1 all are the switch fixed contact shapes of standard, a location hole 7 is arranged in the rear portion leading-out terminal 6, location round pin 10 by pedestal contact box B inserts the location, major loop terminal block 13 is centered on by insulating shield 11, major loop terminal block 13 connects quiet Mume flower contact seat 9 and location round pin 10, location round pin 10 is located at the front end of quiet Mume flower contact seat 9, shirt rim 12 be centered around quiet Mume flower contact seat 9 around, mounting flange 14 is located at the rear end of pedestal contact box B, when band contact box current transformer A is connected with pedestal contact box B, the location hole 7 that location round pin 10 inserts in the back fixed contact 6 of being with contact box current transformer A, the height shirt rim 4 of shirt rim 12 topped current transformers 1.
Very convenient, the accurate positioning of installation and removal of the present utility model, directly at the indoor replacing current transformer of handcart, need not readjust the fixed contact position, compared with prior art, have that installation and removal convenience, contact accurate positioning, handcart interchangeability are good, current ratio is not subjected to any restriction advantages such as (can be as small as 20/5).
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Embodiment:
As shown in Figure 1, the utility model mainly is made up of band contact box current transformer A and pedestal contact box B, band contact box current transformer A has current transformer 1, contact box 2, mounting flange 3, height shirt rim 4, preceding fixed contact 5, back fixed contact 6, location hole 7 and shirt rim group 8, pedestal contact box B has quiet Mume flower contact seat 9, location round pin 10, insulating shield 11, shirt rim 12, major loop terminal block 13 and mounting flange 14, wherein, contact box 2 front ends have mounting flange 3, so that band contact box current transformer A is fixedly mounted on the switch cubicle, the inner chamber of contact box 2 is conical, the inner chamber front end has shirt rim group 8 to increase creepage distance, there is height shirt rim 4 at the rear portion of current transformer 1, plaing increases creepage distance and voltage isolation effect, the function that assist location is also arranged simultaneously, the preceding fixed contact 5 and the back fixed contact 6 (winding terminal) of current transformer 1 all are the switch fixed contact shapes of standard, a location hole 7 is arranged in the rear portion leading-out terminal 6, location round pin 10 by pedestal contact box B inserts the location, major loop terminal block 13 is centered on by insulating shield 11, to guarantee that energized conductor has enough insulation distances over the ground, major loop terminal block 13 connects quiet Mume flower contact seat 9 and location round pin 10, location round pin 10 is located at the front end of quiet Mume flower contact seat 9, shirt rim 12 be centered around quiet Mume flower contact seat 9 around, when band contact box current transformer A is connected with pedestal contact box B, in the location hole 7 that location round pin 10 inserts in the back fixed contact 6 of being with contact box current transformer A, to back fixed contact 6 location, the Mume flower contact 15 of circuit breaker dolly can be inserted convenient and exactly, the height shirt rim 4 of the then topped current transformer 1 in shirt rim 12, do not expose and enough creepage distances are arranged to guarantee to seal energized conductor, simultaneously to the accurate location of current transformer 1 with back fixed contact 6, booster action is also arranged, mounting flange 14 is located at the rear end of pedestal contact box B, so that the pedestal contact box is installed in the switch cubicle.
In the present embodiment, the back top of current transformer 1 is provided with a band cap pin 16, and it can slide in the chute in switch cubicle, plays the assist location effect, and is also helpful to the dismounting current transformer simultaneously.
