Abstract

The utility model discloses an electricity protection test circuit, which comprises a left wire-connecting clamp and a right wire-connecting clamp; a clamping head is arranged at one end of the left wire-connecting clamp; a test conductor wire is connected to the tail end of the wire-connecting clamp; the test conductor wire is connected to a controller; the test circuit is also externally connected to the tail end of the right wire-connecting clamp; an LED (Light Emitting Diode) is connected onto the right wire-connecting clamp in series; and detection circuits between left and right connection wires form a loop. The electricity protection test circuit disclosed by the utility model can greatly save detection time.

Description

Electricity is protected measurement circuit

Technical field

The utility model relates to a kind of electricity and protects measurement circuit.

Background technology

In existing technology; The DUM-48/50H interface aborning, there is following problem in branch testing overlong time problem in the existing technology: 1. mainly be need branch fuse be pulled up with the NT handle along separate routes the time in test; Use frock lead simulation fault along separate routes; And upload to controller, because the shunt fault detection board detection failure reaction time is slower, causes whole electricity to protect the test needs and in test, found in 15 minutes 2.; Detection needed more than 10 minutes along separate routes, had occupied the most of the time of electric guarantor's test.

The utility model content

The utility model provides a kind of electricity that can save detection time to protect measurement circuit.

The utility model technical solution problem provides following scheme:

A kind of electricity is protected measurement circuit; Two binding clips about comprising, an end of said left binding clip is a chuck, the end of said binding clip is connected with test lead; Said test lead is connected with controller; The end of said right binding clip is also outer to be connected with measurement circuit, is in series with a LED light emitting diode on the said right binding clip, and the detection line between the wiring of the said left and right sides constitutes path.

The utility model improves test fixture, deals with problems from principle.Concrete grammar is following: 1. LED light emitting diode of adjunction on the frock lead, whether 2. shunt of test earlier when test waits pending fault to occur and disappears, and measures along separate routes that plate is a non-defective unit, judge good along separate routes then through the light and shade of lamp.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Referring to accompanying drawing, a kind of electricity is protected measurement circuit, two binding clips 1,2 about comprising; One end of said left binding clip 1 is a chuck 3; The end of said left binding clip 1 is connected with test lead 4, and said test lead 4 is connected with controller 5, the also outer measurement circuit 4 that is connected with of the end of said right binding clip 2; Be in series with a LED light emitting diode 6 on the said right binding clip 2, said left and right sides binding clip 1, the detection line between 24 constitute path.

Claims (1)

1. an electricity is protected measurement circuit; Two binding clips about comprising is characterized in that: an end of said left binding clip is a chuck, and the end of said left binding clip is connected with test lead; Said test lead is connected with controller; The end of said right binding clip is also outer to be connected with measurement circuit, is in series with a LED light emitting diode on the said right binding clip, and the detection line between the binding clip of the said left and right sides constitutes path.
