Abstract
The utility model discloses a well door interlocking gear, including blocking lever, interlocking couple, handcart and handcart link gear, interlocking couple sets up on well door plant, and on the blocking lever set up the handcart link gear in well door, the handcart link gear set up and is used for whether being located test position according to the handcart drives the blocking lever and get in touch the connection status with the interlocking on the handcart, the blocking lever is arranged in locking or opens the door plant with the cooperation of interlocking couple. The utility model discloses a cooperation use is geted in touch with interlocking to the blocking lever, only works as the handcart and passes through the spring at test position, blocking lever, and make it and interlock and get in touch separately, door plant openable, the secondary socket can be extracted. In procedural assurance, well door is opened at operating position to the circuit breaker under the non - normal condition to increase operating personnel's safety. The problem of put the cabinet in current handcart and well door do not have chain, even the handcart can be opened at operating position, well door at any time is solved, IP2X's between human body and charged body protection level has been improved.
Description
Technical field
This utility model relates to door interlocking gear in medium voltage switchgear equipment field, particularly one.
Background technology
The most most circuit breaker carts of producer do not have reciprocal interlocking, handcart not to have chain with middle door with the unlatching of middle door, hands
Car is in operating position, and chopper is in operating position, and middle door can arbitrarily be opened, in this case between operator and electrical body
Degree of protection only has IP2X, there is potential safety hazard.Ask mutually or during the fault such as single-phase earthing if now high tension loop has, chopper
Operation combined floodgate is possible to cause personal safety accident.
Accordingly, it would be desirable to the middle door interlocking gear of a kind of operating mechanism safety.
Utility model content
The purpose of this utility model is just to provide the middle door interlocking gear of a kind of operating mechanism safety.
The purpose of this utility model is realized by such technical scheme:
Door interlocking gear in the one that this utility model provides, including blocking lever, interlocking hook, handcart and handcart link gear；
Described interlocking hook is arranged on middle door-plate, and described blocking lever is arranged on the handcart link gear in middle door, and described handcart links
Mechanism be arranged on handcart for according to handcart whether be positioned at testing position drive blocking lever with interlocking hook connection status；Described
Blocking lever is linked up with to coordinate with interlocking and is used for locking or open middle door-plate.
Further, described handcart link gear includes handcart upper plate and roller；Described blocking lever one end is flexibly connected with interlocking hook,
The other end is connected with roller；Described roller is connected with handcart upper plate；Described handcart upper plate drives roller to rotate, so that interlocking
The connection status that bar is connected end with interlocking hook changes.
Further, described blocking lever being provided with spring, described spring one end is connected with blocking lever, and the other end is solid with outside blocking lever
On earnest, it is used for producing pulling force and orders about interlocking hook and separate with blocking lever.
Owing to have employed technique scheme, this utility model has the advantage that
This utility model by blocking lever and interlocking hook with the use of, only when handcart is in testing position, and blocking lever passes through spring,
Being allowed to separate with hook of interlocking, door-plate can be opened, and Secondary socket can be extracted.Program ensures, disconnected under abnormal condition
Road device door in operating position is opened, thus increase the safety of operator.The handcart solving existing middle-placed switch cabinet does not has with middle door
Chain, even if handcart is in operating position, the problem that middle door can be opened at any time, improve the protection of IP2X between human body and electrical body
Grade.
Other advantages of the present utility model, target and feature will be illustrated to a certain extent in the following description, and
To a certain extent, will be apparent to those skilled in the art based on to investigating hereafter, or can be from
Practice of the present utility model is instructed.Target of the present utility model and other advantages can pass through description below and right
Claim realizes and obtains.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows.
Fig. 1 is that blocking lever of the present utility model separates hook schematic diagram.
Fig. 2 is that blocking lever of the present utility model pushes down hook schematic diagram.
Fig. 3 is middle-placed switch cabinet side view schematic diagram of the present utility model.
In figure: 11 be blocking lever, 12 be interlocking hook, 13 be Secondary socket, 21 be roller, 22 be handcart upper plate, 23 be
Handcart.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As it can be seen, door interlocking gear in the one of the present embodiment offer, including blocking lever 11, interlocking hook 12, handcart 23
With handcart link gear；Described interlocking hook is arranged on middle door-plate, and described blocking lever is arranged at the handcart link gear in middle door
On, described handcart link gear be arranged on handcart for according to handcart whether be positioned at testing position drive blocking lever with interlocking hang
Hook connection status；Described blocking lever is linked up with to coordinate with interlocking and is used for locking or open middle door-plate.
Described handcart link gear includes handcart upper plate 22 and roller 21；Described blocking lever one end is flexibly connected with interlocking hook,
The other end is connected with roller；Described roller is connected with handcart upper plate；Described handcart upper plate drives roller to rotate, so that interlocking
The connection status that bar is connected end with interlocking hook changes.
Being provided with spring on described blocking lever, described spring one end is connected with blocking lever, on the other end and blocking lever extenal fixation thing,
For produce pulling force order about interlocking hook separate with blocking lever.
The middle door interlocking gear work process that the present embodiment provides is as follows:
When handcart passes through spring at testing position, blocking lever, being allowed to separate with hook of interlocking, door-plate can be opened, Secondary socket
13 can extract.
When handcart is in operating position, handcart driving rolls, make blocking lever push down hook, middle door-plate can not be opened, and Secondary socket is also
Can not extract.
Therefore, when circuit breaker cart is in operating position, add one safety curtain, thus it requires operator must be according to just
Normal operation sequence operates, i.e. circuit breaker cart must in testing position can be opened door, thus safer.
Further, interlocking hook is provided with emergency unlocking device, during if there is fault, can turn on bolt, i.e. can be taken off interlocking hook；
This device is reasonable in design, simple in construction, and highly versatile is easy for installation, uses reliable.
Finally illustrating, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although with reference to preferably
This utility model has been described in detail by embodiment, it will be understood by those within the art that, can be to this utility model
Technical scheme modify or equivalent, without deviating from objective and the scope of the technical program, its all should contain this
In the middle of the right of utility model.
