Abstract
An overcurrent and opening trip device for type 23 spring operating mechanism includes an overcurrent electromagnet and a tripping electromagnet which comprises a magnetic yoke, a coil, a static iron core and a dynamic iron core and a copper ejector pin. After being pulled in by electrifying, the copper ejector pins of the overcurrent electromagnet and the tripping electromagnet directly drive the tripping bending plate fixed with half shaft by attacking, and the half shaft is driven to rotate at a certain angle, then the rocker arm is opened which realizes overcurrent trip or opening trip of the switch (circuit breaker). Compared with the present technology, the device has the advantages of simple structure, small mechanical wear, high transmission efficiency, provincial copper consumption, low cost, etc.
Description
Technical field
The utility model relates to the overcurrent and the Sub-gate release device of spring operating mechanism, in particular for overcurrent, the Sub-gate release device of 23 type spring operating mechanisms.
Background technology
In the spring operating mechanism of outdoor high-voltage vacuum breaker, must thread off immediately, otherwise cause expansion accident serious consequence for guaranteeing reliability of operation and fail safe, all being provided with when electric current is in overcurrent and separating brake.And the tripping mechanism of 23 type spring operating mechanisms, relation because of the installation site is continuing outmoded structure for a long time, nobody makes improvements old looks always, as shown in Figure 1, when electrical network generation overcurrent, overcurrent electromagnet (right side) adhesive upper punch, its copper push rod 8 must at first push up and hit side top board 7, this side top board is fixed on the left side or the right side of axle 6, be illustrated as and be fixed on the right side, the side top board is subjected to push up and hits angle of back rotating band moving axis 6 revolutions, and the revolution of axle drives again fixes its middle middle top board 5 rotations, middle top board hits dropout bent plate 2 in 3 tops of the transition ejector pin in guide holder 4 again, and then 1 rotation of drive semiaxis reaches overcurrent dropout purpose.When needing separating brake to thread off, top board 5 is hit on copper push rod 8 tops of tripping electromagnet (left side), and middle top board hits dropout bent plate 2 in 3 tops of the transition ejector pin in guide holder 4 equally, and then 1 rotation of drive semiaxis reaches separating brake dropout purpose.Because the copper push rod of overcurrent electromagnet and tripping electromagnet can't directly push up and hit the dropout bent plate, must reach the dropout purpose through correlated parts, therefore, there is complex structure in prior art, the cost height, mechanical loss is big, the defective that transmission efficiency is low, and necessarily require the top of powerful overcurrent electromagnet and making electromagnet to hit power, cause overcurrent electromagnet and tripping electromagnet volume big, consumption copper is many, and manufacturing cost is risen.
Summary of the invention
Goal of the invention of the present utility model all provide in the defective that overcomes prior art a kind of simple in structure, transmission efficiency is high, cost is low, the overcurrent that is used for 23 type spring operating mechanisms, Sub-gate release device that especially overcurrent electromagnet and tripping electromagnet volume are little, consumption copper is economized.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of overcurrent, Sub-gate release device that is used for 23 type spring operating mechanisms, it comprises by yoke, coil, copper sleeve, static iron core, moving iron core, copper push rod and forms overcurrent electromagnet and tripping electromagnet, semiaxis and dropout bent plate are fixed, after it is characterized in that the copper push rod energising adhesive of described overcurrent electromagnet and tripping electromagnet, the copper push rod of overcurrent electromagnet and tripping electromagnet and directly hit on the top with the fixing dropout bent plate of semiaxis.
Compared with prior art, the utility model has carried out improving completely to overcurrent, the Sub-gate release device of 23 type spring operating mechanisms, changed the old structure of continuing to use for a long time, general structure is simplified greatly, reduced mechanical loss, improved transmission efficiency, especially the power requirement to overcurrent electromagnet and tripping electromagnet reduces greatly, dwindled volume, saved raw material and processing cost, every copper loss can be saved more than 100 yuan.
Description of drawings
Fig. 1 is overcurrent, the Sub-gate release device structural representation of prior art.
Fig. 2 is the utility model overcurrent, Sub-gate release device structural representation (the forward and backward coincidence status of overcurrent electromagnet and tripping electromagnet).
Embodiment
Below in conjunction with the accompanying drawings the utility model embodiment is specifically described again.
As shown in Figure 2, the overcurrent that is used for 23 type spring operating mechanisms, Sub-gate release device, it comprises the overcurrent electromagnet and the tripping electromagnet of same structure, overcurrent electromagnet and tripping electromagnet are by yoke 10, coil 11, be fixed on the static iron core 9 on the yoke, static iron core and moving iron core 13 coaxial being installed in the copper sleeve 12, be installed in the copper push rod 8 that static iron core and sound in-core are connected by nut 14, after the electromagnet energising, moving, the static iron core adhesive make iron core drive copper push rod adhesive upper punch, and driving dropout bent plate 2 is hit on the top, because of dropout bent plate and semiaxis 1 fix, rotate counterclockwise certain angle so drive semiaxis, rocking arm is triped, realize that switch (circuit breaker) overcurrent is threaded off or separating brake is threaded off.
