It includes lock body, lock core and handle, and two handles are installed to the symmetry on the lock body, install the lock core between the handle, the opening direction of lock core upwards sets up, and the interlocking structure that lock body, lock core, handle are constituteed installs perpendicularly on the car of chassis, and the opening direction of lock core sets up forward, and the interlocking structure horizontal installation that lock body, lock core, handle are constituteed is on the car of chassis. The utility model discloses guarantee transformer substation's method of operation safe operation on request, the avoid accident takes place, and reliable and stable, the practicality is strong, easily uses widely.
Description
Technical field
The utility model relates to high-tension switch cabinet technical field, be specifically related to 10KV middle-placed switch cabinet interlock.
Background technology
" interlocking " of high-tension switch cabinet be to ensure that power network safe operation, guarantee equipment and personal safety, prevents the important measures of maloperation, this is made explicit provisions by GB3906-1991 " 3-35KV ac metal closing switch gear ", generally " interlocking " is described as: prevent mistake point, falsely close circuit breaker；Prevent on-load from dividing, close isolation switch；Prevent band cable address (conjunction) earth lead (earthed switch)；Prevent line with ground (switch) from closing a floodgate；Prevent mistakenly entering charged chamber, above-mentioned five contents preventing electric misoperation, be called for short " five prevent "." five prevent " locking is to prevent operations staff's maloperation, it is ensured that substation safety runs, and improves the effective measures of power supply reliability.Being interlocked by perfect contact cabinet so that it is reach 10KV high-voltage switch gear " five prevent " locking requirement, make substation safety, reliability service, " five prevent " device is generally taken charge of and is divided into machinery, electric and comprehensive three classes.At present, on market, high-tension switch cabinet type is a lot, and great majority suffer from perfect interlock method, but still has the interlocking especially mechanical interlocking imperfection of many high-tension switch cabinets, still can not be fully achieved " five prevent " requirement.
Existing 10KV middle-placed switch cabinet, " five prevent " measure of single cabinet itself is quite perfect, but specific to power supply entering line, time properly functioning, block switch is at open position, two-way inlet wire split operation, in any case, service entrance switch and isolation switch possess the function of three conjunctions two, realize mechanical electric locking, electric blocking can be easily achieved, but mechanical latching just acquires a certain degree of difficulty, especially to user engineering.
In order to solve the problems referred to above, design a kind of novel 10KV middle-placed switch cabinet interlock or necessary.
Utility model content
For the deficiency existed in prior art, this utility model purpose is to be in that to provide a kind of 10KV middle-placed switch cabinet interlock, simple in construction, reasonable in design, it is ensured that transformer station's method of operation safe operation on request, it is prevented that accident occurs, reliable and stable, practical, it is easy to promote the use of.
To achieve these goals, this utility model is to realize by the following technical solutions: 10KV middle-placed switch cabinet interlock, including lock body, lock core and handle, lock body is symmetrically installed with two handles, being provided with lock core between handle, the interlock of lock body, lock core, handle composition is arranged in lead-in circuit breaker, section switch chassis.
As preferably, the opening direction of described lock core sets up, and the interlock right angle setting of lock body, lock core, handle composition is on a chassis.
As preferably, the opening direction of described lock core is arranged forward, and the interlock of lock body, lock core, handle composition is horizontally arranged in chassis.
The beneficial effects of the utility model: ensure transformer station's method of operation safe operation on request, it is prevented that accident occurs, good stability, reliability is high.
Accompanying drawing explanation
This utility model is described in detail below in conjunction with the drawings and specific embodiments；
Fig. 1 is the vertically arranged structural representation of this utility model；
Fig. 2 is the structural representation that this utility model level is installed.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, this utility model is expanded on further.
With reference to Fig. 1-2, this detailed description of the invention is by the following technical solutions: 10KV middle-placed switch cabinet interlock, including lock body 1, lock core 2 and handle 3, lock body 1 is symmetrically installed with two handles 3, being provided with lock core 2 between handle 3, the interlock of lock body 1, lock core 2, handle 3 composition is arranged in lead-in circuit breaker, section switch chassis.
It should be noted that the opening direction of described lock core 2 sets up, on a chassis, lock need not perforate on cabinet door when installing, it is necessary to open door operation for the interlock right angle setting of lock body 1, lock core 2, handle 3 composition.
Additionally, the opening direction of described lock core 2 is arranged forward, the interlock of lock body 1, lock core 2, handle 3 composition is horizontally arranged in chassis, needs perforate on cabinet door, it is possible to need not open door operation when lock is installed.
This detailed description of the invention installs 202 type mechanical locks additional in lead-in circuit breaker, section switch chassis, two keys of three locks realize, three close two functions, install three circuit breaker carts of guarantee additional and only have two operable devices, the five anti-measures having strengthened 10KV switch cubicle perfect, ensure transformer station's method of operation safe operation on request, it is prevented that peril occurs, and has wide market application foreground.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
