An O-shaped seal ring (3) is arranged between the junction box seat (1) and the junction box cover (2).
Description
Affiliated technical field
The utility model relates to a kind of flame-proof type threephase asynchronous terminal box, it more precisely is a kind of flame-proof type threephase asynchronous terminal box peculiar to vessel, be applied to flameproof motor, usefulness as motor wiring, have degree of protection height, explosive-proof grade height,, characteristics such as inlet wire is flexible, belong to technical field of motors.
Background technology
Because the explosive-proof grade of common serial flame-proof type threephase asynchronous terminal box is Exd II BT4, its degree of protection can only arrive IP55, and can't multi-faceted inlet wire, heater can't be installed, thermistor can't be installed.And marine service motor is owing to be subjected to the influence of ocean climate, and motor need be installed heater and drive tide, thermistor is installed is protected, and requires the motor degree of protection to reach IP56, and explosive-proof grade reaches Exd II CT4.Normal flameproof motor can't satisfy and can't require, and greatly reduces the functional reliability of motor.Therefore press for a kind of novel flame-proof type threephase asynchronous terminal box of development.
Novel flame-proof type threephase asynchronous terminal box, characteristics are that the requirement explosive-proof grade is Exd II CT4, and degree of protection reaches IP56, are fit to multi-faceted inlet wire, are fit to install additional heater, thermistor.
Summary of the invention
The purpose of this utility model is to provide a kind of novel flame-proof type threephase asynchronous terminal box, this motor connecting cartridge can reach explosive-proof grade height, degree of protection height, multi-faceted inlet wire, can install the characteristics of heater, thermistor additional, satisfy the actual state of novel flame-proof type threephase asynchronous, adapt to the usefulness of motor wiring.
The technical scheme that its technical problem that solves the utility model adopts is: optimized Machine Design in the described flame-proof type threephase asynchronous terminal box, under the situation that guarantees enough electric clearances and creepage distance, made junction box seat and connector cover square, the junction box seat four direction all can be installed the armouring anti-explosion packing gland like this, has realized the multi-faceted inlet wire of cable.
Flame-proof type threephase asynchronous terminal box comprises junction box seat, adopts the seam flame proof between junction box seat and the support, and terminal cover, connection bolt that motor body, heater and thermistor are used are housed on junction box seat.A plurality of armouring stuffing boxes can be installed from four orientation.Between junction box seat and connector cover, adopt the seam flame proof, and be furnished with sealing ring and protected.
The beneficial effects of the utility model are: this flame-proof type threephase asynchronous terminal box, have explosive-proof grade height, degree of protection height, multi-faceted inlet wire, and can install the characteristics of heater, thermistor etc. additional.Warp and the supporting use of flame-proof type threephase asynchronous, motor explosive-proof grade height, degree of protection height, multi-faceted inlet wire have been solved, can install key technologies such as heater, thermistor additional, satisfy naval vessel motor actual condition instructions for use, have certain economic benefits.
Below in conjunction with accompanying drawing and example utility model is compared detailed explanation
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
This figure is the flame-proof type threephase asynchronous junction box structure schematic diagram of utility model;
Embodiment
With reference to accompanying drawing, this is a flame-proof type threephase asynchronous junction box structure schematic diagram of the present utility model;
As shown in the figure, flame-proof type threephase asynchronous terminal box comprises junction box seat 1, main motor is installed with terminal cover 4, connection bolt 8 and heater (thermistor) dedicated terminals cover 5, connection bolt 9 on junction box seat 1.In any orientation of junction box seat wall a plurality of stuffing boxes 6,7 can be installed.Be equipped with O RunddichtringO 3 between junction box seat 1 and the connector cover 2.
The optimization of structure
(1) alteration of form is beneficial to multi-faceted inlet wire
The junction box seat of common serial motor connecting cartridge and connector cover all are circular, and the inlet wire mode is also for tradition compresses long cable section of ingoing line, and the inlet wire direction is single.We improve the structure of novel flame-proof type threephase asynchronous terminal box, under the situation that guarantees enough electric clearances and creepage distance, made junction box seat and connector cover square, the junction box seat four direction all can be installed the armouring anti-explosion packing gland like this, has realized the multi-faceted inlet wire of cable.
(2) installation of a plurality of stuffing boxes is beneficial to electric motor protecting
Because novel flame-proof type threephase asynchronous terminal box has increased space heater and the thermistor protector is protected motor.The installation of a plurality of stuffing boxes of side's line box makes the long cable section of ingoing line of space heater and thermistor protector become possibility, thereby has protected motor effectively.
(3) raising of terminal box degree of protection
Because novel flame-proof type threephase asynchronous terminal box changes junction box seat and support cooperation place plane engaging surface into the seam composition surface, and the rubber seal of employing compression material prevents the intrusion of materials such as seawater and dust.Reached the purpose of anti-wave.
(4) raising of terminal box explosive-proof grade
Novel flame-proof type threephase asynchronous terminal box, regulation according to GB3836.2-2000 " explosive gas atmosphere electrical installation part 2 flame-proof type " d " ", change the plane flame proof into the seam flame proof, thereby make motor reach the requirement of Exd II CT4 in theory and practice.
The novel flame-proof type threephase asynchronous terminal box of structure optimization, making the motor explosive-proof grade is Exd II CT4, degree of protection reaches IP56, can be fit to multi-faceted inlet wire, can be fit to install additional heater, thermistor.
Though the utility model is described with reference to above-mentioned example; but those of ordinary skill in the art; will be appreciated that above example only is to be used for illustrating utility model; should understand and wherein can make variations and modifications and do not break away from the utility model in a broad sense; so be not that conduct is to qualification of the present utility model; as long as in connotation scope of the present utility model, to the variation of above-described example, the protection range that distortion all will fall into the utility model claim.
