Abstract
The utility model relates to a kind of electrical interlock high voltage variable cabinet handcart.Comprise and become cabinet handcart and breaker of plastic casing, described change cabinet handcart is connected by electrical interlock with breaker of plastic casing, described electric interlocking circuit is in series by blocking coil and auxiliary contact, described electric interlocking circuit two termination control voltage V2, described blocking coil is arranged on the bottom becoming cabinet handcart, and described auxiliary contact and breaker of plastic casing are mechanically connected.The utility model effectively prevent when there being load, extracts or advances the bad hidden danger that change cabinet handcart used exists out, thus achieve not on-load operation, add the reliability of breaker of plastic casing.
Description
Technical field
The utility model relates to all handcart-types of high pressure and becomes cabinet technical field, particularly relates to a kind of electrical interlock high voltage variable cabinet handcart.
Background technology
Nothing reliably electrical interlocks between the change cabinet used handcart of high pressure in the market and outlet breaker of plastic casing, when breaker of plastic casing is with load, extract out or advance change cabinet handcart used, high-voltage pile interface is easily caused to occur the phenomenon of arcing, not only reduce the useful life of high-voltage pile, even can burn out high-voltage pile.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of electrical interlock high voltage variable cabinet handcart.
Technical solutions of the utility model are as follows:
A kind of electrical interlock high voltage variable cabinet handcart, comprise and become cabinet handcart and breaker of plastic casing, described change cabinet handcart is connected by electrical interlock with breaker of plastic casing, described electric interlocking circuit is in series by blocking coil and auxiliary contact, described electric interlocking circuit two termination control voltage V2, described blocking coil is arranged on the bottom becoming cabinet handcart, and described auxiliary contact and breaker of plastic casing are mechanically connected.
Described control voltage V2 is 220V alternating voltage.
The beneficial effects of the utility model are: auxiliary contact and breaker of plastic casing adopt and be mechanically connected, synchronization action, become cabinet handcart to be connected by electrical interlock with breaker of plastic casing, this design effectively prevent when there being load, the bad hidden danger extracted out or advance change cabinet handcart used to exist, thus realize not on-load operation, add the reliability of breaker of plastic casing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model electrical connection schematic diagram.
Fig. 2 is electric interlocking circuit connection diagram.
Wherein: 1, electrical interlock; 2, blocking coil; 3, auxiliary contact; 4, breaker of plastic casing; 5, cabinet handcart is become; 6, transformer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult Fig. 1 and Fig. 2, a kind of electrical interlock high voltage variable cabinet handcart, comprise and become cabinet handcart 5 and breaker of plastic casing 4, described change cabinet handcart 5 is connected by electrical interlock 1 with breaker of plastic casing 4, described electrical interlock 1 circuit is in series by blocking coil 2 and auxiliary contact 3, described electrical interlock 1 circuit two termination control voltage V2, described blocking coil 2 is arranged on the bottom becoming cabinet handcart 5, and described auxiliary contact 3 are mechanically connected with breaker of plastic casing 4.
Described control voltage V2 is 220V alternating voltage.
Operation principle of the present utility model is: auxiliary contact 3 and breaker of plastic casing 4 adopt and be mechanically connected, synchronization action, become cabinet handcart 5 to be connected by electrical interlock 1 with breaker of plastic casing 4, when switch is in co-bit, blocking coil 2 obtains electric, change cabinet handcart blocking coil 2 used locking, becoming cabinet handcart 5 cannot extract out or advance.When switch is when dividing position, blocking coil 2 dead electricity, change cabinet handcart 5 blocking coil used is opened, and handcart can be extracted out or advance.Effectively prevent when there being load, extracting or advancing the bad hidden danger that change cabinet handcart 5 used exists out, thus realizing not on-load operation, adding the reliability of breaker of plastic casing 4.
Above-mentioned drawings and Examples are only for illustration of the utility model, and any art those of ordinary skill to its suitable change done or modification, or is used other flower pattern instead and made this technical change, all should be considered as not departing from the utility model patent category.
