Description
Technical field
The present invention relates to for electrical domain, specifically a kind of load control terminal Anti-mistrip device.
Background technology
Propelling along with power information acquisition system strengthened research, the old-fashioned load control terminal of part stops the functions such as upper electrographic recording, rate of qualified voltage statistics and optical-fibre communications because not possessing terminal, it is high plus the terminal filed fault rate running more than 5 years, so it is imperative to change Novel load control terminal works.
The client that specially becomes installing load control terminal is generally integrated mill or market, typically use dual power supply, negative control terminal is arranged on main for metered side, can not lead, the switching of available power supply, when user uses stand-by power supply to power, negative control terminal is without working power, the normal work of terminal cannot be ensured, the most do not possesses the condition changing terminal when having a power failure, (load-control equipment is installed to be unsatisfactory for " State Grid Corporation of China's electric power safety working regulation (distribution section) " regulation, safeguarding typically should have a power failure with service work is carried out, carry out if need to not have a power failure, the measure preventing separating brake by mistake should be had) during work.For preventing mistrip from using insulating tape that breaking coil is wrapped up in work on the spot at present, can not have a power failure and carry out negative control terminal replacing, when the node that trips uses normally opened mode, high pressure total cabinet switch trip coil causes end side band 220V voltage, if parcel is tight or adhesive tape broken skin, user can be caused to trip power failure, the lighter affects Electricity customers and produces, manages, and severe one can bring serious economic loss to Electricity customers；When the node that trips uses normally closed mode, carry out terminal replacing and Electricity customers then must be allowed to have a power failure, the reliability of impact power supply and good service.The most existing load control terminal is when performing pre-power purchase, and when user's electricity reaches to alert electricity, the on-the-spot load control terminal run exists the risk of tripping operation power-off without arrearage alarm prompt, Electricity customers.
Summary of the invention
In order to effectively solve the on-the-spot problem changing load control terminal mistrip, improve the reliability of dual power supply switching terminal, on-the-spot alarm after realizing subscriber arrearage, the present invention provides a kind of load control terminal Anti-mistrip device, make tripping operation contact in the case of taking normally opened or normally closed mode, still can complete the work of terminal charged for replacement, improve the efficiency of work, reduce job safety risk, deepen the application of power information acquisition system.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that load control terminal Anti-mistrip device, including base plate, power supply wiring row, the first relay, the second relay, opening button, switch knob, trip(ping) circuit line bank, arrearage chimes of doom light modulation and load control terminal it is fixed with on base plate, the power output end of power supply wiring row and the power input of the first relay connect, and the power output end of the first relay connects with the power input of load control terminal；The normally opened port of trip(ping) circuit line bank, normally closed port and public port are connected with the normally opened port of load control terminal, normally closed port and public port respectively by the second relay；Described opening button and switch knob all connect with the second relay；Arrearage chimes of doom light modulation connects with the warning port of load control terminal.
By accessing high-voltage metering cubicle, negative control controls terminal Anti-mistrip device in use, only needs operator to press opening button, the actuating of relay, can trip(ping) circuit be isolated.
Negative control controls after terminal Anti-mistrip device uses, and needing in the past has a power failure is replaced the operation of terminal, it now is possible to implement under not power-off condition, not only improve power supply reliability, and save the working time, increase the performance of enterprises, provide high-quality, reliable green energy resource to lay the first stone for power customer；Have employed after negative control controls terminal Anti-mistrip device, when dual power supply user's power supply point switch, do not affecting the properly functioning of load control terminal, be truly realized specially becoming customer charge " controlled, controlling, can control "；When changing terminal, can be effectively isolated by breaking coil, it is to avoid subscriber switch mistrip, when pre-power purchase user's dump energy reaches to alert electricity, scene can carry out audible and visual alarm, improve good service level.
Described relay is miniature relay.Compared to auxiliary reclay, (action current is big, service life is long, price, and volume is big, action sensitivity is low) and contact relay (action current is big, service life is long, and function is many, price, volume is big, action sensitivity is low, installs inconvenience), miniature relay low price, action current are little, action sensitivity is high.
Described base plate is epoxy resin board, and cost is low, easily install, most importantly good insulation preformance.
Base plate bottom also has base plate box, base plate box uses stainless steel to make, equipped with handle on base plate box, part wire can be hidden in base plate box, load control terminal Anti-mistrip device is made to seem attractive in appearance, and operating process is not easily broken wire, the handle installed additional makes load control terminal Anti-mistrip device be easy to carry.
