Abstract
The utility model relates to a high-voltage junction box of a high-voltage dust explosion-proof three-phase asynchronous motor. The high-voltage junction box comprises a junction box shell, a junction box cover and a cable outlet. The junction box shell is internally provided with a wiring terminal, a cable is led out from the cable outlet, the junction box cover is connected to the junction box shell in a sealed way through a box cover sealing pad, the junction box shell is in sealed connection with a base of the motor through a base sealing pad, and the cable outlet is provided with a sealing ring, a wiring bucket and a gland head; a connection surface between the junction box cover and the junction box shell is a connection surface with a positioning spigot, and a connection surface between the junction box shell and the base of the motor is also a connection surface with a positioning spigot; and the box cover sealing pad and the base sealing pad are high-temperature-resistant sealing pads. The high-voltage junction box of the high-voltage dust explosion-proof three-phase asynchronous motor, provided by the utility model, has good protection function.
Description
(1), technical field: the utility model relates to a kind of motor connecting cartridge, particularly a kind of high pressure dust explosion protection type threephase asynchronous high-voltage connection box.
(2), background technology: the dust explosion protection motor refer to its shell in accordance with regulations condition manufacture and design, can stop dust to enter in motor casing, though or can not stop dust to enter fully, but its inlet does not hinder the motor safe operation, and the accumulation of inner dust is difficult for producing lights danger, also can not cause the motor of explosive dust mixture blast on every side during use.
Existing high pressure dust explosion protection type threephase asynchronous will satisfy the test of shell protection grade, 6 totally 30 hours cycles of the close test of dirt, satisfy this requirement, high-voltage connection box as dust explosion protection motor critical piece should self satisfy degree of protection, again with the joint face of motor main body on improve protection level, realize requirement of explosion proof.
(3), utility model content:
The technical problems to be solved in the utility model is: not enough for prior art, a kind of protective high pressure dust explosion protection preferably type threephase asynchronous high-voltage connection box is provided.
The technical solution of the utility model:
A kind of high pressure dust explosion protection type threephase asynchronous high-voltage connection box, contain terminal block housings, connector cover and cable outlet mouth, be provided with binding post in terminal block housings, cable is drawn from the cable outlet mouth, connector cover is sealedly connected on terminal block housings by the lid sealing gasket, terminal block housings is tightly connected by the support of support sealing gasket and motor, and cable outlet mouth place is provided with sealing ring, wiring bucket and gland head.
Cable outlet mouth place has adopted the double protection design; Ground floor coordinates with cable by sealing ring, forms the first protection; The second layer coordinates with cable by gland head, forms the second protection.
Joint face between connector cover and terminal block housings is the joint face with positioning spigot, and the joint face between the support of terminal block housings and motor also is the joint face with positioning spigot.Make like this high-voltage connection box improve again degree of protection when satisfying requirement of explosion proof.
Lid sealing gasket and support sealing gasket are the refractory seals pad.
The beneficial effects of the utility model:
1. between connector cover of the present utility model and terminal block housings, all adopted sealing gasket to add connected mode with positioning spigot between the support of terminal block housings and motor, cable outlet mouth place adopts sealing ring, wiring bucket and gland head to reach double protection, therefore, barrier propterty of the present utility model is better.
(4), description of drawings:
Fig. 1 is the structural representation of high pressure dust explosion protection type threephase asynchronous high-voltage connection box.
(5), embodiment:
Referring to Fig. 1, in figure, high pressure dust explosion protection type threephase asynchronous high-voltage connection box contains terminal block housings 1, connector cover 2 and cable outlet mouth 11, be provided with binding post 10 in terminal block housings 1, cable 7 is drawn from cable outlet mouth 11, connector cover 2 is sealedly connected on terminal block housings 1 by lid sealing gasket 3, and terminal block housings 1 is tightly connected by support sealing gasket 4 support 5 with motor, and cable outlet mouth 11 places are provided with sealing ring 8, wiring bucket 9 and gland head 6.
Joint face between connector cover 2 and terminal block housings 1 is the joint face with positioning spigot, and the joint face between the support 5 of terminal block housings 1 and motor also is the joint face with positioning spigot.Make like this high-voltage connection box improve again degree of protection when satisfying requirement of explosion proof.
Lid sealing gasket 3 and support sealing gasket 4 are the refractory seals pad.
Claims (3)
1. high pressure dust explosion protection type threephase asynchronous high-voltage connection box, contain terminal block housings, connector cover and cable outlet mouth, be provided with binding post in terminal block housings, cable is drawn from the cable outlet mouth, it is characterized in that: connector cover is sealedly connected on terminal block housings by the lid sealing gasket, terminal block housings is tightly connected by the support of support sealing gasket and motor, and cable outlet mouth place is provided with sealing ring, wiring bucket and gland head.
