Description
Technical field
The invention belongs to electrical equipment technical fields, and in particular to a kind of 10kV/35kV middle-placed switch cabinet wheelbarrow switch stroke is opened
Guan Chong moves device.
Background technique
There are two travel switches, i.e. testing position and operating position for the position on 10kV/35kV middle-placed switch cabinet wheelbarrow switch chassis.
Easily cause travel switch not in place due to designing, manufacture etc. the problems such as, if the operating position of especially travel switch is not
It is not in place in place, particularly in operational process, it will affect equipment reliability service, even need the processing that has a power failure, and 10kV/35kV is opened
If the route for closing band is directly user, has a power failure and will impact to good service.
Operating position closing locking is by reflecting that the limit switch contact of handcart position seals in the closing circuit of breaker
Come what is realized, cause greatly since travel switch original designs installation and the unreasonable maintenance of the faults frequent in use difficulty of wiring
Circuit breaker cart is there is very big accident potential and thus caused a closing locking failure and leads to incorrect switching accident
The substantial equipment accident for causing breaker vacuum pipe explosion handcart to scrap, and system voltage fluctuation is caused to seriously affect production.
Travel switch be set at acted at operating position its normal opened contact be serially connected in breaker closing circuit control it is disconnected
The closing operation of road device, operating position refer to that the moving contact of circuit breaker cart is kissed completely with the static contact being fixed on switch cabinet
The position of splice grafting touching, breaker must just allow the logical tripping of travel switch normal opened contact closure structure at this time of combined floodgate power transmission in the position
Indicate circuit, if green light instruction closing circuit it is intact allow next step breaker switching-on operation travel switch act too early or
Contact clamping stagnation does not pop up green light, and also brighten the hair goes out the error signal for allowing to close a floodgate.Progress closing operation is dangerous at this time, if stroke
Switch is failure to actuate at operating position, and green light, which does not work, can not connect closing circuit delay combined floodgate power transmission influence production, by above-mentioned
It can be seen that on the one hand travel switch is used as the importance of safety prevention measure on the one hand to add new fault point therefore must again
It must guarantee that the durability safety of the quick property performance of reliability of travel switch movement can just be accomplished safely and efficiently to power to exist to ask
Topic.
Summary of the invention
In order to avoid the above various shortcoming, the invention proposes a kind of safe and reliable wheelbarrow switch travel switches to move dress again
It sets, the device wiring is simple, can thoroughly prevent the insecure problem of stroke contact, ensure that the safe and stable operation of power grid.
The invention adopts a technical scheme as: a kind of 10kV/35kV middle-placed switch cabinet wheelbarrow switch travel switch moves device again, including
Wheelbarrow switch, Crane Rail, stroke touching ball, compressed spring and the prudent motor type relay of self-insurance, the wheelbarrow switch is along driving rail
Road movement, the stroke touching ball are arranged below Crane Rail by compressed spring, and so that stroke touching ball is partly exposed at handcart and open
In the travelling route of pass, movable contact is installed on the stroke touching ball, the movable contact can be active in the self-insurance
Between the normally closed stationary contact and normally opened stationary contact of prudent motor type relay.
Further, the movable contact is normal with the prudent motor type relay of self-insurance when wheelbarrow switch is not contacted with stroke touching ball
Close stationary contact point contact；The movable contact is normally opened quiet with the prudent motor type relay of self-insurance when wheelbarrow switch is contacted with stroke touching ball
Contact contact.
The positive effect of the present invention is: the present invention is by introducing the prudent motor type relay of self-insurance, it is ensured that middle-placed switch cabinet wheelbarrow switch
Travel switch acts at operating position, avoids various mistakes；The power off time for shortening middle-placed switch cabinet wheelbarrow switch, improves
Labor efficiency has ensured the stable operation of electric system.
Detailed description of the invention
Fig. 1 is structure principle chart one of the invention；
Fig. 2 is structure principle chart two of the invention；
In figure: 1- wheelbarrow switch, 2- stroke touch ball, 3- Crane Rail, 4- compressed spring, the normally closed stationary contact of 5-, 6- movable contact, 7-
Normally opened stationary contact, the prudent motor type relay of 8- self-insurance.
Specific embodiment
The present invention will be further described below with reference to the drawings.
As depicted in figs. 1 and 2, a kind of 10kV/35kV middle-placed switch cabinet wheelbarrow switch travel switch moves device again, including handcart is opened
Close 1, Crane Rail 3, stroke touching ball 2, compressed spring 4 and the prudent motor type relay 8 of self-insurance.Wheelbarrow switch 1 in middle-placed switch cabinet
It is moved along Crane Rail 3, stroke touches ball and is arranged below Crane Rail 3 by compressed spring 4, and is exposed at stroke touching ball 2 half
In the travelling route of wheelbarrow switch 1, movable contact 6 is installed on stroke touching ball 2, the movable contact 6 can be active in self-sustaining
Between the normally closed stationary contact 5 and normally opened stationary contact 7 of weight motor type relay 8.
The course of work of the invention are as follows: when wheelbarrow switch 1 is advanced to operating position along Crane Rail 3, wheelbarrow switch is squeezed
Stroke touches ball 2, and stroke touching ball 2 is sunk by compressed spring 4, the movable contact 6 and normally opened stationary contact being now placed on stroke touching ball 2
7 conductings start the prudent motor type relay 8 of self-insurance, are returned by the combined floodgate that prudent 8 output contact of motor type relay of self-insurance completes to seal in breaker
The division of switch is realized on road.
The present invention is using the purpose of the prudent motor type relay 8 of self-insurance: reliable and secure stroke of the wheelbarrow switch 1 in current position
It is interior, it is movable in any case, even if movable contact 6 and normally opened 7 poor contact of stationary contact, also do not cause output contact to return, ensure that
The integrity of closing circuit；Certainly, if the active strokes of wheelbarrow switch 1 are excessive, current location is had left, namely being unsatisfactory for can
When by the requirement of operating position, stroke touching ball 2 is returned by compressed spring 4, and movable contact 6 and normally closed stationary contact 5 are connected, so that from
Weight motor type relay 8 is kept to return, the output contact of the prudent motor type relay 8 of self-insurance returns, and closing circuit is obstructed, completes circuit and closes
Lock function.
The present invention is to guarantee the reliable secondary heavy dynamic device of travel switch, it is ensured that 10kV/35kV wheelbarrow switch is working
The reliability service of position ensure that the reliability of travel switch position contact contact and the accuracy of position contact point signal transmission, energy
Enough it is widely used in high-tension switch cabinet.
