Description
Technical field
The utility model is related to a kind of electrical instrument, especially a kind of to measure powered investigation instrument of visiting one house after another.
Background technology
Happened occasionally it is well known that being complained caused by " meter wiring error ", current check method is to take a pair
The power failure verification of one resident family, testing device carry out the verification inspection of electric energy meter and indoor line to methods such as lines.Check in this way, though
The problem of " meter wiring error " so can be eliminated, it is ensured that family table wiring is correct, but have a power failure to verify makes troubles to user's life,
And workload is big, efficiency is low, it is difficult to which rapid corrigendum, customer evaluation is low.Therefore, design one kind and measure powered investigation instrument of visiting one house after another, be
The current technical issues that need to address.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind and measures powered investigation instrument of visiting one house after another.
The technical scheme in the invention for solving the technical problem is：
Powered investigation instrument of visiting one house after another is measured, is made up of machine tool and handset, machine tool is by power carrier communication R-T unit I, electronics
Formula voltmeter I and earth leakage protective device are constituted, and the hot terminal of power carrier communication R-T unit I is sub, electronic type voltage table I
The sub- parallel connection of hot terminal of hot terminal and earth leakage protective device is followed by insulating clamp I, power carrier communication R-T unit I
Zero line binding post, the zero line binding post parallel connection of the zero line binding post of electronic type voltage table I and earth leakage protective device is followed by
Insulating clamp II, the ground wire binding post of earth leakage protective device connects insulating clamp III；Handset is by power carrier communication R-T unit II
With electronic type voltage table II, the live wire of hot terminal and electronic type voltage table II of power carrier communication R-T unit II connects
Line terminals parallel connection is followed by insulating clamp IV, zero line binding post and the electronic type voltage table II of power carrier communication R-T unit II
Zero line binding post parallel connection be followed by insulated wire V.Using low-voltage power line as signal transmission passage, high frequency is sent by machine tool
Carrier signal, handset receive the transmission high-frequency carrier signal and feedback signal by machine tool, if machine tool and handset success communication,
Show not visit one house after another, it is on the contrary then show to visit one house after another.By machine tool insulating clamp from gauge table leading-out terminal changing-over end of incoming cables, indicator lamp still dodges
It is bright, illustrate to visit one house after another.Such as indicator lamp Chang Liang, illustrate that gauge table inlet-outlet line is reversed, correct at once.
Visit one house after another, " table-line " relation how is determined rapidly：
1. handset（At user）Insulating clamp keeps original position constant.
2. machine tool insulating clamp is changed into gauge table leading-out terminal one by one.
3. until composite aircraft successful matching, it may be determined that the gauge table is client's gauge table residing for handset.
Power carrier communication R-T unit I, electronic type voltage table I and earth leakage protective device are fixed in machine tool shell, insulated wire
Folder I, insulating clamp II and insulating clamp III are exposed outside machine tool shell by respective wire；The He of power carrier communication R-T unit II
Electronic type voltage table II is fixed in handset shell, insulating clamp IV and is connect insulated wire V and is exposed handset shell by respective wire
Outside.
Compared with prior art, the utility model investigation visit one house after another do not have a power failure, efficiency high, work it is light, corrigendum is rapid, accurate
Really.Customer evaluation is high.
Brief description of the drawings
Fig. 1 is functional block diagram of the present utility model.
