Abstract
The utility model discloses an electric anti-jumping pole-mounted vacuum circuit breaker, which comprises an anti-jumping relay arranged on the mechanism front plate of the pole-mounted vacuum circuit breaker; the coil of the anti-jumping relay is connected in parallel to a closing loop of the pole-mounted circuit breaker, a group of normally closed contacts are connected in series to the closing loop of the pole-mounted vacuum circuit breaker, and the normally closed contacts are used for disconnecting the closing loop of the pole-mounted vacuum circuit breaker to prevent jumping. When the switching-on output end always has switching-on voltage due to the reasons of adhesion of switching-on or remote-on contacts of the switching-on loop and the like, the normally closed contact of the relay is disconnected at the moment, the switching-on loop is cut off, and the equipment is prevented from jumping. The utility model discloses the realization of preventing the jump does not need special electric device, also need not to change current equipment structure and can realize that circuit breaker electric on the post prevents the jump, and is simple and convenient handy, furthest's the cost of having saved.
Description
Technical Field
The utility model belongs to the technical field of distribution equipment on the post, a electric pole-mounted vacuum circuit breaker who prevents jumping is related to.
Background
The pole-mounted vacuum circuit breaker is used as mainstream power equipment of 12KV line distribution networks in recent years and is widely applied to various fields of power distribution networks. Therefore, different lines in different fields have more extensive and complex requirements for the accuracy of the protection current. When the breaker is switched on a permanent fault circuit, the relay protection acts, and the breaker trips; if the closing command of the circuit breaker is not released at the moment, namely due to the reasons of closing loop switching or remote joint adhesion and the like, the closing output end always has closing voltage, the circuit breaker is closed again, and the repeated switching on and off of the circuit breaker is called circuit breaker jumping. The occurrence of a circuit breaker jump condition may cause the circuit breaker to explode. The anti-jumping device, i.e., the anti-jumping device, must be installed for a possible closing jumping problem of the circuit breaker. And the pole-mounted circuit breaker is used as main stream power equipment of a distribution network line, and in the stage of high-speed development of distribution network automation, the improvement of an anti-tripping function is to ensure the reliable operation of a power supply line.
Disclosure of Invention
The utility model provides an electric pole-mounted vacuum circuit breaker who prevents jumping, the operation that makes pole-mounted vacuum circuit breaker can be reliable stops the problem of emergence equipment "jump".
The utility model discloses a realize through following technical scheme:
an electrical anti-jump pole top circuit breaker comprises an anti-jump relay arranged on a mechanism front plate of a pole top vacuum circuit breaker; wherein, prevent jumping relay's coil and connect in the combined floodgate return circuit of post-mounted circuit breaker, a set of normally closed contact concatenates in the combined floodgate return circuit of post-mounted vacuum circuit breaker, breaks off post-mounted vacuum circuit breaker's combined floodgate return circuit through its normally closed contact in order to prevent jumping:
if the closing loop is electrified all the time, and the coil of the anti-jump relay is electrified all the time, the normally closed contact connected in series in the closing loop is kept open all the time; if the closing output end has closing voltage all the time, the normally closed contact of the anti-jump relay is disconnected, and a closing loop is disconnected.
The jump-proof relay is a relay which is opened and closed twice.
Compared with the prior art, the utility model discloses following profitable technological effect has:
the utility model provides an electric anti-jumping pole-mounted circuit breaker, which is characterized in that a relay is arranged on a front plate of a pole-mounted vacuum circuit breaker mechanism, and a closing circuit is disconnected through a normally closed contact of the relay; when the switching-on output end always has switching-on voltage due to the reasons of adhesion of switching-on or remote-on contacts of the switching-on loop and the like, the normally closed contact of the relay is disconnected at the moment, the switching-on loop is cut off, and the equipment is prevented from jumping. The utility model discloses the realization of preventing the jump does not need special electric device, also need not to change current equipment structure and can realize that circuit breaker electric on the post prevents the jump, and is simple and convenient handy, furthest's the cost of having saved.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic diagram of the circuit connection of the present invention;
fig. 3 is a schematic connection diagram of the connection terminal of the present invention;
wherein, 1 is the anti-jump relay, and 2 is the mechanism front bezel.
Detailed Description
The present invention will now be described in further detail with reference to the attached drawings, which are provided for purposes of illustration and not limitation.
Referring to fig. 1 and 2, the utility model relates to an electric anti-jump vacuum circuit breaker on column, which installs an anti-jump relay 1 on the mechanism front plate 2 of the vacuum circuit breaker on column, wherein, the coil of the anti-jump relay 1 is connected in parallel in the closing circuit of the circuit breaker on column, and a group of normally closed contacts of the anti-jump relay 1 are connected in series in the closing circuit of the circuit breaker; the normally closed contact of the breaker is used for disconnecting the closing loop to prevent the equipment from jumping.
If the closing loop is electrified all the time, the relay coil is electrified all the time, namely, the contacts connected in series in the closing loop are kept open all the time, and the vacuum circuit breaker on the column works normally; when the switching-on output end always has switching-on voltage due to the reasons of adhesion of switching-on or remote-connection points of the switching-on loop and the like, the normally closed contact of the relay is disconnected at the moment, the switching-on loop is cut off, and the equipment is prevented from jumping.
The utility model discloses a realization of preventing jumping does not need special electric device, also need not to change current equipment structure and can realize that circuit breaker electric prevents jumping on the post.
Specifically, the utility model discloses a relay that two are opened two and are closed is as preventing jumping relay, refers to the circuit connection that figure 2 shows and the binding post connected mode that figure 3 shows, will prevent jumping relay and connect in circuit breaker combined floodgate return circuit, breaks off combined floodgate return circuit through its normally closed contact and prevents that equipment from taking place "jump".
The embodiments given above are preferred examples for implementing the present invention, and the present invention is not limited to the above-described embodiments. Any non-essential addition and replacement made by the technical features of the technical solution of the present invention by those skilled in the art all belong to the protection scope of the present invention.
