Abstract
The utility model discloses a kind of multifunction electric source tray, it comprises the power line be wrapped on power supply disks; The two ends of power supply disks are flexibly connected with support; The side of support and bottom are respectively equipped with telescopic lever and movable pulley; One end of power line is fixedly installed on the connecting terminal block of power supply disks inside, and to be contacted an earth leakage protective device by wire; The other end of power line is provided with relaying protection joint; Earth leakage protective device is connected with relaying protection interface and alternating current accessory power outlet respectively by wire; Relaying protection interface and alternating current accessory power outlet are separately positioned on the two ends of power supply disks.Because power line one end is connected with relaying protection interface and alternating current accessory power outlet respectively by earth leakage protective device, when there is ground connection or phase fault, earth leakage protective device action tripping air switch, thus deenergization, prevent from burning out test apparatus; Telescopic lever and movable pulley can move easily, and power cord wrap storage is saved space and do not tied a knot, without the need to extra circumscripted power line.
Description
technical field
The utility model belongs to power supply disks technical field, is specifically related to a kind of at substation relay protection test middle and long distance interpolation tested number/AC power output and the multifunction electric source tray with leak source defencive function.
background technology
In prior art, the structure of relaying protection test wire is made up of 2-3m quad and two ends test plug, although this mode is widely used, but there is many drawbacks, folding and unfolding is carried out because test wire is often intertwined after a procedure, a large amount of time need be spent when reusing to make knotting place of cable in order, carry inconvenience; And, the magnitude of current of present intelligent station protective device, voltage are digital quantity, take from the merge cells at protected interval and PT interval respectively, when the merge cells at protected spacing distance PT interval is far away, existing experiment line can not meet the demands, and need to adopt the many end to end modes of experiment line to realize, and the many end to end modes of experiment line bring inconvenience to staff, require a great deal of time and muscle power do preliminary preparation, affect operating efficiency; And if existing test wire occur insulation fault time often burn out reaying protection test device and produce serious electrical leakage problems, can cause any property loss, fail safe is also very poor.
summary of the invention
The purpose of this utility model solves prior art to there is storage inconvenience, without the technical problem of earth leakage protective, inefficiency and poor stability, provide a kind of multifunction electric source tray, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of multifunction electric source tray of the utility model, it comprises the power line be wrapped on power supply disks; Its main points are: the two ends of described power supply disks are flexibly connected with support by bearing pedestal; The side of described support and bottom are respectively equipped with telescopic lever and movable pulley; One end of described power line is fixedly installed on the connecting terminal block of power supply disks inside, and to be contacted an earth leakage protective device by wire; The other end of described power line is provided with relaying protection joint; Described earth leakage protective device is connected with relaying protection interface and alternating current accessory power outlet respectively by wire; Described relaying protection interface and alternating current accessory power outlet are separately positioned on the two ends of power supply disks.
The utility model structure is simple, easy to use, because power cord wrap is placed on power supply disks, and one end is connected with relaying protection interface and alternating current accessory power outlet respectively by earth leakage protective device, when there is ground connection or phase fault, earth leakage protective device action tripping air switch, thus deenergization, prevent from burning out test apparatus, fail safe is high; Telescopic lever and movable pulley can move easily, and space is saved in power cord wrap storage, does not tie a knot; The length of power line increases, without the need to extra circumscripted power line.The utility model solves prior art storage inconvenience, without the technical problem of earth leakage protective, inefficiency and poor stability.

embodiment
See figures.1.and.2, the utility model it comprise the power line be wrapped on power supply disks 5; The two ends of described power supply disks 5 are flexibly connected with support 2 by bearing pedestal; The side of described support 2 and bottom are respectively equipped with telescopic lever 1 and movable pulley 3; One end of described power line is fixedly installed on the connecting terminal block of power supply disks 5 inside, and to be contacted an earth leakage protective device by wire; The other end of described power line is provided with relaying protection joint; Described earth leakage protective device is connected with relaying protection interface 4 and alternating current accessory power outlet 7 respectively by wire; Described relaying protection interface 4 and alternating current accessory power outlet 7 are separately positioned on the two ends of power supply disks 5.
Power line in the utility model uses four-core 4mm 2 high-quality multiply soft copper heart yearn, maximum withstand voltage 1000V, and length can reach 50 meters, can meet the requirement of experimental voltage in work of transformer substation and spacing distance completely; The connecting terminal block of reaying protection test instrument and protective device all uses special socket, for the voltage of guarantee and standardization terminal board carries out transmitting; The relaying protection joint of the power line other end is connected to the object apparatus be verified, and so just extends the delivered length of tested number, achieves the long-range output of test simulation amount; Meanwhile, relaying protection joint and relaying protection interface respectively with not homophase colour code note to facilitate differentiation (yellow-A phase, green-B phase, redness-C phase, black-N phase), and corresponding with power line phase form and aspect; This device also has creepage protection function; when there is ground connection or phase fault; after reaching the setting current of earth leakage protective device on device, earth leakage protective device is by tripping switch thus isolated leaky site, solves single long test wire and is short-circuited when dosage and burns out the problem of test apparatus.
The beneficial effects of the utility model are, can realize long distance and add test simulation amount, the phenomenon that creepage protection function can avoid test apparatus to burn out or the person gets an electric shock occurs, and traditional electrical source tray is integrated the function making it have and provide AC power; In addition, this structure is simple, be easy to carry transport; Power supply disks one end is provided with two alternating current accessory power outlets, and availability test instrument uses.
