It sets.
Background technique
Synthetic tower electric furnace is enclosed in synthetic tower, and in high-temperature high-pressure work environment, catalyst dust is more, is driving
When stage and fluctuation, suitable temperature is provided for catalyst, activates its performance, ammonia synthesis reaction is enable to go on smoothly.Cause
This, the safe and stable operation of synthetic tower electric furnace is one of necessary condition of Ammonia Production, and whether the insulation against ground of electric furnace closes
Lattice are the prerequisites that judges electric furnace and whether can be safely operated.
By low-voltage electrical code requirement, synthetic tower electric furnace insulation against ground value is measured with 500V megohm meter not less than 0.5M Ω,
Electric furnace can be just powered on.But in practical operation, synthetic tower electric furnace insulation values are in 0.2M Ω hereinafter, even being surveyed sometimes with megameter
Obtaining insulation values is 0, but has measured 1000 Ω or so with multimeter, if can run and be difficult to judge.
Summary of the invention
The invention aims to quick and precisely judge whether electric furnace can be powered on operation, it is exhausted to make up existing synthetic tower electric furnace
The deficiency of edge detection instrument, we design a kind of synthetic tower electric furnace insulation detection device, can not for having solved 500V megohm meter
Accurately judge whether synthetic tower electric furnace insulation against ground value uses under Qualification,.
It adopts the technical scheme that in order to solve the above problem:
A kind of synthetic tower electric furnace insulation detection device, including commutator, light bulb, lamp cap, fuse and several conducting wires,
In, select two 100W/220V light bulbs in parallel, and connect with the 5A fuse and commutator, the commutator
Two non-moving ends, one end earthing pole, on another insulated conductor for terminating at Band clamp,
Before detection, middle position is first got into the moved end of the commutator, the another of the fuse terminates at 220V
In AC power source, then the commutator is got to the non-moving end for being connected to ground wire, two 100W/220V light bulbs shine just
Often, illustrate that the detector element is normal, confirmation synthesis furnace power switch is already off and hangs warning mark, and the double-throw is opened
The clip that pass is connected to insulated conductor is clipped on the conducting wire of synthesis electric furnace, and confirms that contact is good, the moved end of the commutator
One end of Band clamp is got to,
<1>if the 100W/220V light bulb does not work, illustrate that electric furnace insulation against ground is qualified, removing detection device can be opened with power transmission
Open electric furnace；
<2>if the 100W/220V bulb brightness is normal, illustrate that electric furnace is grounded, need overhaul plan；
<3>if the 100W/220V light bulb glimmer, illustrate that electric furnace insulation is unqualified, need that technological measure is taken to be blown off
And drying, until when testing the 100W/220V light bulb and not working, electric furnace can be opened with power transmission by removing detection device.
Implementing a kind of beneficial effect of synthetic tower electric furnace insulation detection device of the present invention is:
1. the synthetic tower electric furnace insulation detection device can not need electric furnace and take out stitches, as long as there is alternating current 220V power supply to can be used；
2. the use of the synthetic tower electric furnace insulation detection device can not only substantially increase the standard of diagnosis synthetic tower electric furnace failure
Exactness accelerates job schedule, is also greatly reduced the labor intensity of worker；
3. the synthetic tower electric furnace insulation detection device is safe and efficient, simple and easy, low in cost, processing installation is easy to implement.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.
Fig. 1 is the schematic illustration of the present embodiment synthetic tower electric furnace insulation detection device.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
Embodiment:
Referring to Fig. 1, the present embodiment proposes a kind of synthetic tower electric furnace insulation detection device, including a commutator, two 100W/
220V light bulb, two lamp caps, a 5A fuse and several conducting wires, wherein two 100W/220V light bulbs are in parallel, and with institute
It states 5A fuse and commutator is connected, two non-moving ends of the commutator, it is another to terminate at band on an end Jie ground wire
On the insulated conductor of clip.Before use, middle position is got in the moved end of the commutator, the another of the fuse is terminated at
In 220V AC power source, then the commutator is got to the non-moving end for being connected to ground wire, two 100W/220V light bulb hairs
Light is normal, illustrates that the detector element is normal, and confirmation synthesis furnace power switch is already off and hangs warning mark, described double
The clip that throw switch is connected to insulated conductor is clipped on the conducting wire of synthesis electric furnace, and confirms that contact is good, the commutator
