Description
Technical field
The utility model relates generally to isolating switch mechanical anti-misoperation locking field, mainly is the positive and negative isolating switch mechanical anti-misoperation locking device of a kind of 110KV.
Background technology
The bus of electric substation all is the double bus scheme mode, an equipment part connects positive female operation at interval, another part connects secondary female operation, when interval equipment connects the female operation of pair, the positive female plug-in strip open position in interval, this moment, switch bus bar side earthing isolator did not have locking device, can run jointly whenever and wherever possible and close the bus bar side earthing isolator.During switch bus bar side earthing isolator closing position, can close negative female isolating switch whenever and wherever possible.Between the positive and negative female isolating switch of space before, there are not anti-band earthing isolator combined floodgate, charged splice grafting ground isolating switch mechanical latching function.In electric power system, prevent electric misoperation, guarantee to send out, the safe and reliable operation of controller switching equipment and electric line is primarily also to be one of most important requirement, just in case have an accident, to cause enormous economic loss, very harmful, even jeopardize equipment and personal safety.It brings serious threat not only for the safe operation of electric power system, and society is caused bigger influence.For this reason, the power industry mandatory requirement takes to prevent the electric misoperation device in electric power system, to satisfy electric power " five is anti-" requirement.
So-called electric power " five is anti-", be meant: prevent that mistake from dividing, mistake is closed circuit breaker, prevent the on-load branch, close isolating switch, prevent charged hanging earthing conductor (or splice grafting ground switch), prevent to be with earth connection (or not separating earthed switch) to close isolating switch, prevent mistakenly entering charged chamber.Prevent that the electric misoperation device is a lot, such as Mechanically programm's lock, electromagnetic lock, microcomputer locking etc.But anti-band earthing isolator closes a floodgate to not having between positive and negative female isolating switch, charged splice grafting ground isolating switch mechanical latching function, and existing mechanical locking, electromagnetic lock, microcomputer locking etc. are all not competent.In service at power equipment, current band earthing isolator closes a floodgate and the pernicious misoperation fault of charged splice grafting ground isolating switch slowly constantly occurs.Cause electric grid large area power cut, even can cause serious accidents such as device damage, casualties.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of rational in infrastructure, the positive and negative isolating switch mechanical anti-misoperation locking device of the 110KV of dependable performance.
The utility model solves the technical scheme that its technical problem adopts: the positive and negative isolating switch mechanical anti-misoperation locking device of this 110KV, mainly comprise the horizontal kinematic link of switch bus bar side earthing isolator, connecting rod, the negative horizontal kinematic link of female isolating switch, connecting lever and disc crank, the two ends of connecting rod are connected with kinematic link connector I and kinematic link connector II, kinematic link connector I is connected with the horizontal kinematic link of switch bus bar side earthing isolator by connecting lever, and kinematic link connector II is connected with the negative horizontal kinematic link of female isolating switch by disc crank.
Be connected by bearing I between described kinematic link connector I and the connecting lever.
Be connected by bearing I I between described kinematic link connector II and the disc crank.
Described disc crank is provided with combined floodgate positioner and separating brake positioner.
Described disc crank is connected with disc crank by bearing I II and supports.
The effect that the utility model is useful is: but when only having or not electricity, just closes the utility model isolating switch when splice grafting ground isolating switch, no earthing isolator.Ensured in the electric power system that the safe and reliable operation of electrical network or equipment has been guaranteed network (equipment) and personal safety, the generation of having avoided charged splice grafting ground isolating switch or band earthing isolator to close the pernicious misoperation fault of isolating switch.The positive and negative female isolating switch mechanical latching advanced design, rational in infrastructure, multiple functional, the dependable performance that adopt are a kind of novel prevent to be with earthing isolator combined floodgate, charged splice grafting ground isolating switch mechanical anti-misoperation locking devices.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: the horizontal kinematic link 1 of switch bus bar side earthing isolator, connecting lever 2, kinematic link connector I 3, bearing I 4, connecting rod 5, disc crank supports 6, nut 7, kinematic link connector II 8, bearing I I 9, bearing I II10, the negative horizontal kinematic link 11 of female isolating switch, combined floodgate positioner 12, separating brake positioner 13, disc crank 14.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, this 110KV just, negative isolating switch mechanical anti-misoperation locking device, mainly comprise the horizontal kinematic link 1 of switch bus bar side earthing isolator, connecting rod 5, the negative horizontal kinematic link 11 of female isolating switch, connecting lever 2 and disc crank 14, whole anti-misoperation locking device is a metal material, the two ends of connecting rod 5 are connected with kinematic link connector I 3 and kinematic link connector II 8, fixing between connecting rod 5 and kinematic link connector I 3 and the kinematic link connector II 8 by nut 7, kinematic link connector I 3 is the U type, kinematic link connector II 8 is the L type, kinematic link connector I 3 is connected with the horizontal kinematic link 1 of switch bus bar side earthing isolator by connecting lever 2, be connected by bearing I 4 between kinematic link connector I 3 and the connecting lever 2, kinematic link connector II 8 is connected with the horizontal kinematic link 11 of negative female isolating switch by disc crank 14, be connected by bearing I I 9 between kinematic link connector II 8 and the disc crank 14, disc crank 14 is connected with disc crank by bearing I II10 and supports 6, and disc crank 14 is provided with combined floodgate positioner 12 and separating brake positioner 13.
When switch bus bar side earthing isolator during at closing position, positive and negative female isolating switch mechanical locking device will be born female isolating-switch locking in the separating brake position, and this moment, negative female isolating switch just can't close a floodgate.When negative female isolating switch during at closing position, positive and negative female isolating switch mechanical anti-misoperation locking device is latched in the separating brake position with switch bus bar side earthing isolator, and this moment, switch bus bar side earthing isolator can't close.Reach and prevent to be with earthing isolator, charged splice grafting ground isolating switch mechanical latching function between positive and negative female isolating switch.Utilized theory of mechanics, and rational in infrastructure, multiple functional, dependable performance, reach and prevent that charged splice grafting ground isolating switch, band earthing isolator from closing the isolating switch misoperation, guarantee the purpose of the safe and reliable operation of power system device, created benefit simultaneously.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
