Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment one of switchgear of the invention, as shown in Fig. 2 to Figure 10, switchgear includes switch cabinet body 10,
Mutual inductor and other electrical component (not shown)s are installed on switch cabinet body 10.Switch cabinet body in the present embodiment
10 include cable vault 20, and mutual inductor is mounted on the side cabinet 100 of cable vault 20.On side cabinet 100 in the present embodiment
If there are three mutual inductors, respectively A phase mutual inductor 310, B phase mutual inductor 320 and C phase mutual inductor 330, three mutual inductors are electricity
Mutual inductor is pressed, and C phase mutual inductor 330 is arranged close to the front end of switch cabinet body 10, A phase mutual inductor 310 is close to switch cabinet body
10 rear end setting.For convenience of mutual inductor to be mounted on side cabinet 100, mutual inductor installation is fixed on side cabinet 100
Structure, mutual inductor installation structure include the side plate hooking structure being fixed on side cabinet and are fixed on mutual inductor and side plate hook
Hanging hang structure hooks cooperation so that mutual inductor is mounted on the mutual inductor hooking structure on side cabinet 100, and mutual inductor installation structure is also
Including the fixed structure being fixed on mutual inductor on side cabinet 100.By side plate hooking structure and with mutual inductor hooking structure
Cooperation is hooked, mutual inductor can be mounted on side cabinet 100, carry out the pre-installation of mutual inductor, passes through fixed structure pair later
Installation is fixed in mutual inductor, and mutual inductor is arranged and fixed conveniently, and effectively improves the assembly efficiency of mutual inductor；In addition, can be used
Relevant auxiliary tool carries out mounting for mutual inductor, is operated, is mentioned by the installation that an operator can be easily accomplished mutual inductor
The high safety of installation personnel.It is tired to solve existing mutual inductor installation when longitudinally mounted mutual inductor existing in the prior art
Difficult problem.The above mutual inductor of one, two or three can be equipped on side cabinet in other embodiments；Mutual inductor can also be
Current transformer.
As shown in Figure 4, it is contemplated that the space in switchgear is limited, it has not been convenient to mutual inductor is carried out in switch cabinet body 10
It mounts, the side plate hooking structure in the present embodiment includes horizontally disposed sliding rail 50.Carry out when mounting of mutual inductor, can first by
Mutual inductor hooking structure is hung on one end on the outside of the close switchgear of sliding rail 50, then passes through mutual inductor hooking structure and sliding rail
50, which are slidably matched, is pushed to installation site for mutual inductor.For mutual inductor hooking structure is reliably mounted on sliding rail 50, this reality
Applying the sliding rail 50 in example is groove type sliding rail, and groove type sliding rail is dovetail groove type sliding rail.In the present embodiment, mutual inductor hooks knot
Structure includes connecting plate 60 and the hook 601 that is fixed on connecting plate 60, and being slidably matched by hook 601 with groove type sliding rail will be mutual
Sensor is mounted on side cabinet.For reliably mutual inductor is mounted on side cabinet, the hook 601 in the present embodiment is also
Oat tail groove structure, hook 601 are slidably matched by oat tail groove structure and mutual inductor are mounted on sliding rail 50, structure with sliding rail 50
Simply, easy to process.In other embodiments, side plate hooking structure can be the one, two or three being fixed on side cabinet
Above hook hooks cooperation by mutual inductor hooking structure and hook and mutual inductor is mounted on side cabinet；Sliding rail can also
For convex groove type sliding rail；Groove type sliding rail can also for U-lag, annular groove etc., other be convenient and link up with the bathtub constructions for hooking cooperation；.
It should be noted that connecting plate 60 is the connection of bar shaped in the present embodiment for the modularization installation for realizing mutual inductor
Plate, and such A phase mutual inductor 310, B phase mutual inductor 320 and C phase mutual inductance there are three mutual inductor installation site are set on connecting plate 60
330 3 mutual inductors of device are each attached on connecting plate 60.Three mutual inductors install by same mutual inductor installation structure solid
It is fixed, same sliding rail 50 and connecting plate 60 are shared, is fixed, is greatly improved by the installation that three mutual inductors can be completed in once mounting
The installation effectiveness of mutual inductor.In other embodiments, a mutual inductor installation site can also be only set on each connecting plate, into
One mutual inductor is once only installed when the installation of row mutual inductor is fixed；Can also be set as needed on connecting plate two or three with
On mutual inductor installation site；Connecting plate can also be not provided on mutual inductor, hook is directly anchored on mutual inductor.
In view of when hook 601 is slidably matched along sliding rail 50, sliding rail 50 may be skidded off when carrying out the installation of mutual inductor
Outside, or even sliding rail 50 is completely disengaged, the mutual inductor installation structure in the present embodiment further includes the edge for being fixed on sliding rail 50
The endface of length direction is to limit the locating part 30 that mutual inductor hooking structure is in sliding rail 50.Sliding rail 50 is along its length
End face be equipped with sliding rail hole, the sliding rail hole in the present embodiment is threaded hole, correspondingly, as shown in Figure 9 and Figure 10, locating part 30
It is equipped with corresponding with sliding rail hole so that bolt passes through and locating part 30 is fixed on to the locating part hole 301 on sliding rail 50.In addition, such as
Shown in Fig. 3, the locating part in the present embodiment is L shape, and locating part 30 further includes keeping off with the face backwards to side cabinet 100 of mutual inductor
The flanging only cooperated.By locating part 30, not only the hook being fixed on mutual inductor can be effectively prevent to skid off outside sliding rail 50, it can also
Width direction to mutual inductor along switchgear is preferably limited, and the connective stability of mutual inductor is increased.In other implementations
In example, locating part can be not provided with；It can also be not provided with sliding rail hole on sliding rail, locating part is directly fixed by the modes such as welding, being bonded
In sliding rail one end；Locating part can also be connected directly between on side cabinet；Locating part can also be linear type, semi-ring without flanging
Other locating parts such as shape.
As shown in figure 3, the fixed knot for convenience of the connective stability of mutual inductor and mutual inductor installation structure, in the present embodiment
Structure includes the support plate 70 being fixed on side cabinet 100, and mutual inductor is fixedly mounted so that mutual inductor is fixed on cabinet in support plate 70
On side plate 100.Sliding rail 50 and support plate 70 in the present embodiment are arranged along the up and down direction of switch cabinet body 10, and sliding rail 50
One is respectively provided with support plate 70.Cabinet body side is mounted on by hook 601 and the hook cooperation of sliding rail 50 in this way on the upside of mutual inductor
It on plate 100, is fixed on side cabinet 100 on the downside of mutual inductor by support plate 70, mutual inductor installation structure is simple, and installs solid
It is fixed convenient.In other embodiments, support plate and sliding rail can also be arranged along the up and down direction of switch cabinet body；Sliding rail can also be along opening
The up and down direction for closing cabinet cabinet body is equipped at intervals with two or more, and support plate may be provided between adjacent sliding rail at this time or setting exists
The lower section of bottom sliding rail or the top that the top sliding rail is set；Support plate can also be between the up and down direction of switch cabinet body
Every being equipped with two or more, each support plate can be respectively positioned on the either above or below of sliding rail at this time, be also disposed at sliding rail up and down direction
