Abstract
A kind of split type explosion-proof type three-phase asynchronous motor junction box, is made up of connector cover, junction box seat, terminal block and several stuffing boxes.It is characterized in that, when ensureing electric clearance and creepage distance, junction box seat and connector cover all being done squarely, such junction box seat four direction all can installing explosion-proof type stuffing box, realize multi-faceted outlet; Terminal box is separated with motor, and terminal box base is full-enclosed structure, and back panel wiring plate is convenient to wiring; Junction box seat has four external installation towers, the installation site of terminal box is selected arbitrarily by user.This junction box structure is simple, workable, applied range, highly versatile, and freely, cost is low, has certain economic benefit in terminal box installation site.
Description
Art
The utility model relates to the manufacture field of threephase asynchronous, more precisely a kind of explosion-proof type three-phase asynchronous motor junction box.
Background technology
As shown in Figure 1, complex structure, wiring is loaded down with trivial details, with motor body close fit for traditional explosion-proof type three-phase asynchronous motor junction box.
As Fig. 4 sequence number 13 be explosion-proof wiring cassette holder with motor body coordinate seam, the feature of this terminal box is that explosive-proof grade its fit clearance higher less cooperation seam length is longer, get up more difficult and terminal box and motor body in actual installation must one_to_one corresponding, and the position of terminal box is determined by motor body.
If Fig. 4 sequence number 14 is anti-explosion terminal box wiring part, comprise connection bolt, terminal sleeve and locked spacer.This wiring part size is by explosive-proof grade requirement, and practical operation is got up more loaded down with trivial details.For the requirement of mounting heater and thermistor, junction box seat and wiring part all need open form again.Motor cost height is long for delivery date.
Therefore, we have developed a kind of split type explosion-proof type three-phase asynchronous motor junction box.
Summary of the invention
This junction box structure is simple, easy to operate, and universal strong is cost-saving, locus applying flexible.
The utility model solves the technical scheme that its technical problem adopts: this terminal box is made up of connector cover, junction box seat, terminal block and several stuffing boxes, it is characterized in that when ensureing enough electric clearances and creepage distance, junction box seat and connector cover are all done squarely, such junction box seat four direction all can install explosion-proof type stuffing box, achieve multi-faceted outlet; Terminal box is separated with motor body, and inside has terminal block to be convenient to terminal block; Junction box seat there is installation tower that four external.
The beneficial effects of the utility model are:
1. this kind of split type explosion-proof type three-phase asynchronous motor junction box is separated with casing, and as shown in Figure 1, terminal box can be arranged on optional position, any direction.This anti-explosion terminal box highly versatile, for explosive-proof grade be ExdIIBT4 and ExdIICT4, the terminal box of ExdIICT5 can replace by the terminal box of a kind of ExdIICT5; And terminal box does not affect by motor body, seat No. be 80 ~ 112 share a terminal box, seat No. be 132 ~ 200 share a terminal box, seat No. be 225 ~ 280 share a terminal box, whole series only has three terminal boxes as can be seen here.Greatly reduce motor cost, motor component is shared, operator is more prone to distinguish and processing.
2. this kind of split type explosion-proof type three-phase asynchronous motor junction box structure is simple, as shown in Figure 3, the cable joint of motor down-lead is directly introduced terminal block and can complete wiring, can mounting heater, thermistor, does not need to open template separately, workable.
In sum, this kind of split type explosion-proof type three-phase asynchronous motor junction box, structure is simple, workable, applied range, highly versatile, and freely, cost is low, has certain economic benefit in terminal box installation site.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and enforcement, the utility model is further illustrated.
Fig. 1 is the utility model junction box structure vertical view;
Fig. 2 is the utility model junction box structure front view
Fig. 3 is the connection diagram of the utility model terminal box and motor body
Fig. 4 is traditional anti-explosion terminal box structural representation;
The title of the utility model terminal box parts in figure:
1-anti-explosion packing gland (user side); 2-installs tower; 3-earthing device; 4-ground plate; 5-anti-explosion packing gland (motor down-lead end); 6-connector cover; 7-junction box seat; 8-the utility model anti-explosion terminal box; 9-terminal box mounting seat; 10-motor down-lead; Stuffing box on 11-motor body; 12-motor body.
Embodiment
The implementation process of this terminal box:
1. junction box seat (sequence number 7) and connector cover (sequence number 6) matched in clearance, its gap reaches the highest explosive-proof grade ExdIICT5 of current motor, connector cover (sequence number 6) and junction box seat (sequence number 7) are furnished with " O " RunddichtringO and are protected, and its degree of protection can reach IP66;
2. as Fig. 4 motor down-lead (sequence number 10) is drawn from the anti-explosion packing gland (sequence number 11) motor body, introduce in anti-explosion packing gland (sequence number 5) corresponding to junction box seat (sequence number 7), stuffing box (sequence number 1) (sequence number 5) and junction box seat (sequence number 7) mating surface are threaded flame-proof type;
3., if Fig. 2 junction box seat (sequence number 7) bottom is totally enclosed type, terminal block (sequence number 4) is directly installed to junction box seat (sequence number 7) bottom, ensures its enough electric clearance and creepage distance;
4. the position of terminal box mounting seat (sequence number 9) is freely formulated by user, and the utility model terminal box (sequence number 8) is arranged on base (sequence number 9);
5. according to user's request mounting heater and temperature element, upper stuffing box (sequence number 1) (sequence number 5) increasing respective numbers of junction box seat (sequence number 7).
A kind of split type explosion-proof type three-phase asynchronous motor junction box, as the use of the wiring of motor, applied range, can be applicable to peculiar to vessel or land Flame-Proof Three-Phase Induction Motors, stuffing box (sequence number 1), (sequence number 5) position are flexible, wiring is simple, and not by the impact of casing line outlet change in size, user installation position nimbly and freely.
Claims (1)
1. a split type explosion-proof type three-phase asynchronous motor junction box is made up of junction box seat, connector cover, terminal block and several anti-explosion packing glands, it is characterized in that when ensureing enough electric clearances and creepage distance, junction box seat and connector cover are all done squarely, such junction box seat four direction all can install explosion-proof type stuffing box, realize multi-faceted outlet; Terminal box is separated with motor body, and inside has terminal block to be convenient to terminal block; Junction box seat there is installation tower that four external.
