So-called five anti-being: prevent that on-load from dividing, closing isolating switch; Prevent from dividing and closing line breaker, on-load switch, contactor by mistake by mistake; Prevent from closing when earthing switch is in make position the switches such as line breaker, on-load switch, contactor (being called again " preventing that line with ground from closing a floodgate "); Prevent that charged mistiming from closing earthing switch (claim again " preventing live connection of ground wire "); Prevent " five the is anti-" chain functions such as mistakenly entering into charged isolation room.
Ground lock be a kind of meet prevent from being with cable address (closing) grounding wire (earthing switch), line with ground (earthing switch) closes the mechanical lock of line breaker, isolating switch requirement.Electromagnetic lock is a kind of electric-controlled mechanical interlock that prevents the maloperation of high voltage switchgear equipment generation electrical equipment.Ground connection electromagnetic lock is a kind of electric appliance interlocking devices of a large amount of uses in electrical assemblies switchgear equipment system, its objective is a kind of safety measures for power consumption of taking in order to guarantee the normal work of electrical equipment and personal safety, can prevent the generation of misoperation of electrical equipment.
Ground wire electromagnetic lock is the widely used a kind of ground connection blocking device in current transformer station, power plant, during work, operating personnel insert ground wire in ground connection electromagnetic lock, by electromagnetic lock, realize the locking of the ground connection of maintenance of equipment or circuit and earth wire to prevent that mistake from hanging, mistake dismounting ground wire, thereby guarantee operating personnel's personal safety, therefore, the reliability of ground wire electromagnetic lock is extremely important.
Common ground wire electromagnetic lock in use, after ground wire inserts, directly touch microswitch, be difficult to hold dynamics and the distance triggering, inappropriate load is applied directly on microswitch, easily damage microswitch, microswitch was lost efficacy, affected reliability and the application life of electromagnetic lock; When electromagnetic lock is arranged in open air, owing to often installing and removing ground wire, ground wire entrance is exposed in external environment condition, makes foreign matter can enter ground wire electromagnetic lock inner, causes inner member actual effect simultaneously; Above-mentioned various problems easily causes ground connection bad, and serious threat, to operating personnel's the person and device security, exists great potential safety hazard.
Summary of the invention
The utility model discloses a kind of ground connection electromagnetic lock, the functional structure modularization of ground connection electromagnetic lock, more perfect function, rational in infrastructure, operate comfortable, easy to maintenance, the reliability and the safety that have further improved ground connection electromagnetic lock.
The utility model takes following technical scheme to realize:
A ground wire electromagnetic lock, includes housing and pedestal; Wherein, wiring terminal and electric-magnetic lock mechanism are installed on pedestal; Electric-magnetic lock mechanism top is provided with some microswitch components, middlely patches passage for ground wire; It is characterized in that, patch in passage and be provided with and touch plug and elastic component, when ground wire inserts, touch plug and trigger microswitch, signal is spread out of; When ground wire is extracted, shake-up plug is blocked and is patched passage, prevents that foreign matter from entering.
According to the present invention, described housing is comprised of protecgulum and bonnet.
According to the present invention, described some microswitches are fixedly mounted on plug both sides side by side by holder, by plug sidewall, trigger microswitch and constant with microswitch parallel distance.
According to the present invention, described microswitch component is selected from least 2 microswitches that title is arranged in juxtaposition, preferably at least 4 microswitches.
According to the present invention, described plug is led by guide finger and resets by elastic component.
According to the present invention, described electromagnetic lock also comprises being arranged on and patches parameatal hoodle assembly, wherein said hoodle assembly and ground wire groove fit, and by electric-magnetic lock, mechanism is spacing, indirectly realizes the locking to ground wire.
According to the present invention, described hoodle assembly is preferably occurring, at least comprises 2, preferably includes 4, or 6.
According to the present invention, described elastic component can be spring or bellows.
Feature of the present utility model is: after ground wire inserts, bottom line head upper groove coordinates with hoodle, the feel that generation puts in place, promote to touch plug simultaneously, touch plug and lead and touch microswitch by guide finger, and constant with microswitch parallel distance, the triggering dynamics of the microswitch effectively guaranteeing and triggering distance, the microswitch life-span is guaranteed, has improved the reliability of electromagnetic lock.
