[technical field]
The utility model relates to the high-voltage transforming system, specifically relates to a kind of transformer room net door interlock.
[background technology]
In order to ensure electric power system and personnel's safety, when electric power system mesohigh breaker closing when transformer send electricity, the net door of transformer room needs locking.In the prior art, the transformer room of box-type substation net door mostly adopts electromagnetic lock, and what minority adopted is the microcomputor program lock.The shortcoming of electromagnetic lock is, on the one hand, the failure rate of electromagnetic lock coil is very high, often need overhaul, on the other hand, this electromagnetism Key for lock just can be opened easily, thereby has bigger risk, for example when transformer was charged, personnel were strayed into the transformer room and just cause serious electric shock accidents easily.Compare with electromagnetic lock, though the microcomputor program lock is comparatively reliable, yet its cost is higher, and inconvenience is installed, so be not widely used.Therefore, it is necessary developing a kind of simple in structure, safe and reliable, easy to use and lower-cost transformer room net door interlock.
[utility model content]
For addressing the above problem, the utility model discloses a kind of transformer room net door interlock, this transformer room's net door interlock is simple in structure, safe and reliable, easy to use and cost is lower, can realize closing a floodgate when transformer send electricity the net door automatic blocking of transformer room when primary cut-out.
The technical scheme that the utility model is taked is: a kind of transformer room net door interlock, at least comprise primary cut-out rotating shaft, torque arm, pull bar, pivoted arm, rotating shaft, support, hammerlock and interlocking lock body, one end of described pivoted arm is articulated on the support by rotating shaft, the other end of pivoted arm articulates pull bar, and this pull bar links to each other with torque arm on being arranged on the primary cut-out rotating shaft; One end of described hammerlock is articulated on the support by rotating shaft, and the other end of hammerlock is articulated in the interlocking lock body; This transformer room net door interlock also comprise one be arranged at that transformer room's net door is gone up and with the corresponding lockhole of interlocking lock body.
Wherein, described chain lock body comprises push rod, lock pin and elastomeric element at least, and this push rod one end connects hammerlock, and the other end connects lock pin, also is provided with elastomeric element on this lock pin, and lock pin can translation insert or withdraw from lockhole; Described primary cut-out rotating shaft is high voltage load switch rotating shaft or high voltage isolator rotating shaft.
The beneficial effects of the utility model are, this transformer room net door interlock is simple in structure, reliable in function, easy to use and cost is lower, utilize the torque arm campaign of primary cut-out rotating shaft to make chain lock body cooperate lockhole that the net door is carried out locking or release, finished the automatic realization in sending electricity and power operation of locking, unlocking function, when preventing that transformer is charged, personnel are strayed into the transformer room and cause electric shock accidents.

Fig. 1 is the schematic top plan view of transformer room;
Fig. 2 is in the schematic diagram of blocking for transformer room's net door interlock;
Fig. 3 is in the schematic diagram of released state for transformer room's net door interlock.
The Reference numeral and the part that relate among the figure are as follows:
100. primary cut-out rotating shaft 101. torque arm
102. pull bar 103. pivoted arms
200. support 201. rotating shafts
300. interlocking lock body 301. hammerlocks
302. push rod 303. lock pins
304. elastomeric element 305. lockholes
400. transformer
[embodiment]
Below in conjunction with embodiment and with reference to accompanying drawing the utility model is further described:
Fig. 1 is the schematic top plan view of transformer room.Referring to Fig. 1, the both sides of transformer 400 respectively are provided with a net door interlock.
Fig. 2 nets the schematic diagram that the door interlock is in blocking for the transformer room, and Fig. 3 is in the schematic diagram of released state for transformer room's net door interlock.
Referring to Fig. 2 and Fig. 3, a kind of transformer room net door interlock, at least comprise primary cut-out rotating shaft 100, torque arm 101, pull bar 102, pivoted arm 103, rotating shaft 201, support 200, hammerlock 301 and interlocking lock body 300, one end of described pivoted arm 103 is articulated on the support 200 by rotating shaft 201, the other end of pivoted arm 103 articulates pull bar 102, and this pull bar 102 links to each other with torque arm 101 on being arranged on primary cut-out rotating shaft 100; One end of described hammerlock 301 is articulated on the support 200 by rotating shaft 201, and the other end of hammerlock 301 is articulated in interlocking lock body 300; This transformer room net door interlock also comprises one and is arranged at that transformer room's net door is gone up and the lockhole 305 corresponding with interlocking lock body 300.
Wherein, described chain lock body 300 comprises push rod 302, lock pin 303 and elastomeric element 304 at least, and these push rod 302 1 ends connect hammerlock 301, and the other end connects lock pin 303, also be provided with elastomeric element 304 on this lock pin 303, lock pin 303 can translation insert or withdraw from lockhole 305; Described primary cut-out rotating shaft 100 is high voltage load switch rotating shaft or high voltage isolator rotating shaft.
As shown in Figure 2, when primary cut-out closes a floodgate when transformer send electricity or preparation to send electricity, torque arm in the primary cut-out rotating shaft 100 is changeed for 101 times, torque arm 101 drives pull bar 102 and pivoted arm 103 moves downward, under the drive of pivoted arm 103, primary cut-out rotating shaft 100 is rotated to lockhole 305 directions on support 200, the rotation of primary cut-out rotating shaft 100 makes hammerlock 301 rotate thereupon, hammerlock 301 drives push rod 302 and moves to lockhole 305 directions, thereby promote lock pin 303 reaches and insert lockhole 305, make interlock be in blocking.
As shown in Figure 3, when the primary cut-out separating brake when transformer cuts off the power supply, each element direction of action of interlock, change in the torque arm 101 in the primary cut-out rotating shaft 100, torque arm 101 drives pull bar 102 and pivoted arm 103 moves upward, lock pin 303 withdraws from lockhole 305 under elastomeric element 304 effects, hammerlock 301 and push rod 302 make interlock be in released state to away from the motion of lockhole 305 directions.
Thus, transformer room's net door interlock has been finished the automatic realization in sending electricity and power operation of locking, unlocking function.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; can also make some improvements and modifications, these improvements and modifications also should be considered as in the protection range of the present utility model.
