Abstract
The utility model discloses the simple earth detector of storage battery of electric locomotive, include current-limiting resistance R1 and R2, stabilivolt D1 and D2, diode D3 and D4, two ends after current-limiting resistance R1 and R2 series connection and series connection are connected with the positive and negative electrode of storage battery of electric locomotive, connected the coil connection of relay K 1 between current-limiting resistance R1 and R2 by node, be connected in parallel on the coil of relay K 1 after stabilivolt D1 and diode D3 series connection, stabilivolt D2 and diode D4 series connection.This utility model once occurs under drain conditions at storage battery of electric locomotive in colliery, can cut off the power supply that accumulator is powered to electric locomotive immediately, forbid running, and this apparatus structure is simple, and reliability is high, low cost.
Description
Technical field
This utility model relates generally to detection of electrical leakage field, is specifically related to a kind of storage battery of electric locomotive simple detection of electrical leakage dress
Put.
Background technology
In shaft production, electric locomotive is by substantial amounts of use.But due to the existence of coal mine gas, once there is leakage in electric locomotive
Electricity produces spark will directly threaten mine safety, and the simple earth detector of storage battery of electric locomotive of the present utility model can be effective
Solve this problem, prevent spark from producing.
Utility model content
This utility model purpose is contemplated to make up the defect of prior art, it is provided that a kind of storage battery of electric locomotive simply leaks electricity
Detection device.
This utility model is achieved through the following technical solutions:
The simple earth detector of storage battery of electric locomotive, it is characterised in that: include current-limiting resistance R1 and R2, stabilivolt D1
With D2, diode D3 and D4, the two ends after current-limiting resistance R1 and R2 series connection and series connection connect with the positive and negative electrode of storage battery of electric locomotive
Connect, between current-limiting resistance R1 and R2, connected the coil connection of relay, stabilivolt D1 and diode D3 series connection, voltage stabilizing by node
It is connected in parallel on the coil of relay after pipe D2 and diode D4 series connection.
Principle of the present utility model is:
1, power pack, introduces battery tension and enters measure loop by current-limiting resistance R1 and R2 current-limiting resistance.
2, measure loop, after electric locomotive negative or positive electrode leaks electricity, forms loop with relay and allows relay adhesive.By
It is direct current 24V in relay, for ensureing that relay can lean against parallel connection direct 24V stabilivolt on relay coil, prevents voltage anti-
Turn parallel diode on relay coil.Negative pole electric leakage by coil adhesive, makes voltage steady through D1, D2 by R1 resistance simultaneously
Being scheduled on 24V, positive pole electric leakage by coil adhesive, makes voltage stabilization at 24V through D3, D4 by R2 resistance simultaneously.
3, control loop, after relay adhesive, connect the normally closed some disconnection on major loop and allow accumulator power-off, and then ensure
Downhole safety.
The utility model has the advantages that:
This utility model once occurs under drain conditions at storage battery of electric locomotive in colliery, can immediately cut off accumulator to
The power supply that electric locomotive is powered, forbids running, and this apparatus structure is simple, and reliability is high, low cost.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
As it is shown in figure 1, the simple earth detector of storage battery of electric locomotive, include current-limiting resistance R1 and R2, stabilivolt D1
With D2, diode D3 and D4, the two ends after current-limiting resistance R1 and R2 series connection and series connection connect with the positive and negative electrode of storage battery of electric locomotive
Connecing, connected the coil connection of relay K 1 between current-limiting resistance R1 and R2 by node, stabilivolt D1 and diode D3 connects, surely
It is connected in parallel on the coil of relay K 1 after pressure pipe D2 and diode D4 series connection.
