Embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
As shown in Figure 1, a kind of low pressure nuclear phase instrument mainly is made up of interconnective current-collecting device and apparent electric installation, and current-collecting device mainly is made up of first nuclear phase stick 1, and the end of first nuclear phase stick 1 is socketed with first insulated handle 3, and the bottom is used for contacting with object under test.
Second nuclear phase stick 2 that apparent electric installation comprises that liquid crystal display 5 is fixedly connected with said liquid crystal display 5 one sides, second insulated handle 4 that is fixedly connected on said liquid crystal display opposite side, liquid crystal display is used for display digit and voltage.Promptly adopt the common on the market common liquid crystals screen that the illumination reflection shows that passes through, select the passive passive matrix type LCD of STN liquid crystal display.First nuclear phase stick 1 and second nuclear phase stick 2 all are common insulation rod, and first insulated handle 1 and second insulated handle 2 all are the hollow type structure.
Display device commonly used has two kinds of electronic type and mechanical types.Electronic type is to adopt liquid crystal display to show phase place and voltage, and its advantage is a clear display, and voltage is accurate to a position, and long service life is easy to maintenance, but cost of manufacture is high slightly; Mechanical type is to utilize electromagnetic induction principle to show phase place, though simple in structure, easy to make, cost is low, later maintenance inconvenience.Comprehensive consideration easy to use, the display device of the utility model adopts the liquid crystal display of electronic type, and this liquid crystal display adopts commonly used on the market getting final product.
Adopt nuclear phase stick to form current-collecting device in the utility model, this belongs to direct contact-type current-collecting device, and it utilizes clavate parts contact power receiving section position, and contact is reliable, and is easy and simple to handle, do not have dangerous; And wire clamp contact-type current-collecting device in the past utilizes wire clamp to clamp the power receiving section position, though contact is reliable, operation inconvenience has certain risk.
Directly the clavate parts of contact-type current-collecting device can adopt two kinds of scalable insulation rod or common insulation rods.Scalable insulation rod can stretch as its name suggests, and is easy to carry, but the cost height damages; And common insulation rod is made simply, and solid and reliable, cost is low.Considering from the integrated cost aspect, adopt common insulation rod as nuclear phase stick, is an embodiment preferred.
First insulated handle 1 is connected through insulated conductor 6 with second insulated handle 2, thereby said apparent electric installation and current-collecting device are communicated with.Insulated conductor 6 adopts common insulated conductor.From cost consideration, can adopt common insulated conductor.
Assemble current-collecting device and apparent electric installation respectively, again the two is linked to each other through insulated conductor.According to the needs of reality test, can suitably adjust the length or the diameter of insulation rod (being nuclear phase stick).In novel distribution substation, busbar is 20 centimetres with the distance of net door, need not put in the net door in order to guarantee enough securities hand when the nuclear phase, and consider easy to carryly, takes all factors into consideration, and confirms that insulation rod length is 40 centimetres.Be applicable to the electrical verification of novel low pressure feeder pillar, then power receiving section divides the diameter must be less than 2 millimeters, and length is greater than 3 centimetres.Phase and phase ultimate range is 60 centimetres on the transformer and distribution power station busbar, and then the connecting line between two nuclear phase sticks needs 60 centimeter length at least.
Look the thing requirement according to different, also can adopt the liquid crystal displays of different sizes according to client's needs.The liquid crystal display that numeral shows generally is divided into common liquid crystals screen and luminous liquid crystal display.The principle that the common liquid crystals screen adopts the illumination reflection to show, clear display under illumination, cost is low; And luminous liquid crystal display shows through electrical source luminescent, and dull thread also can clearly show, needs luminous electric furnace, and to having relatively high expectations of power supply, cost is also higher.The present invention preferably adopts the common liquid crystals screen.
Common on the market liquid crystal display has passive passive matrix type LCD of STN (white and black displays, the low consumption cost is low) and tft active matrix liquid crystal display TFT liquid crystal display at present.Assess in the face of the liquid crystal display material from practicality, cost and reliability are tripartite, adopting the liquid crystal display material of STN is preferred scheme.
In another embodiment, said insulated conductor is telescopic insulated conductor, and is as shown in Figure 2.Telescopic insulated wire dielectric strength is high, and is easy to carry, flexible operation; Common insulated wire insulation is general, and inconvenience is disliked in operation slightly, and is easy to wear.Telescopic insulated conductor more helps carrying and preserving.
In another embodiment, first nuclear phase stick 1 and second nuclear phase stick 2 all are scalable insulation rod.Scalable insulation rod cost is high slightly, when needed, also can adopt the insulation rod of extension type to come as first and second nuclear phase sticks.
The low pressure nuclear phase instrument of the utility model is simple for production, and cost is relatively low, and the single-piece cost of manufacture can have the prospect of extensive popularization adaptable across existing low pressure nuclear phase workplace about 400 yuan.
