Description
The present invention relates to a kind of ohmic load testing equipment, be specially adapted to the adjustment of charging and discharging of accumulator and silicon controlled rectifier.
The operate as normal of communications facilitys such as railway area automatic telephone, long-haul carrier phone, telegram all must rely on the accumulator of power supply room that power supply is provided.How could provide to safe and high quality power supply, the guarantee accumulator is normally powered, and just need do the adjustment test that discharges and recharges with the silicon controlled rectifier charger to accumulator.In construction was produced, one group of new accumulator will reach normal running status, and the data that will provide by producer is carried out several times the work that discharges and recharges to accumulator usually, treats can come into operation after its stable performance.This work, still the performance of accumulator is not desired, is a requisite operation of subscriber checking producer accumulator capacity, performance quality yet; The charging of accumulator provides after by silicon controlled rectifier alternating current 220V/380V being transformed into the 24V/60V direct current, so can come into operation after must debugging after testing the rectifier of purchasing installation.
The discharge of above-mentioned battery pack, silicon controlled rectifier detects debugging and ordinary maintenance all needs a kind of equipment that replaces its load, i.e. and our alleged fictitious load realizes.
At present, this fictitious load has two kinds of forms:
1, water resistance method
The water resistance method is to pour a small amount of sulfuric acid again into the water that tank or water pot are filled with about 80%, after inserting two pole plates again, lead-in wire is received the output terminal of accumulator or rectifier, seal in reometer, by change in the water sulfuric acid concentration and change two pole plates distance and area in water and guarantee constant-current discharge.The shortcoming that the method exists is: regulate difficulty, sulfuric acid concentration is wayward, and polar plate spacing needs often change, because the variation of its conductance of sulfuric acid solution heating power will directly have influence on the size of electric current, the instrument difficult needs many people's operations, and labour intensity is big and acid mist harmful.
2. slide wire resistance method
The slide wire resistance method is with several swept resistances and connects, and receives the output terminal of accumulator or current regulator, seal in reometer, guarantees constant-current discharge by the change resistance value.The method is convenient than the water resistance method, but still has following shortcoming:
A, slide wire resistance rated current are little, and heavy-current discharge needs also to connect several, and the valency height is uneconomical;
B, travelling arm and coiling often have the loose contact phenomenon, and inconvenience is regulated;
C, lead-in wire are many, connect trouble, need many people's operations;
D, occupied ground are big, are difficult for carrying.
The objective of the invention is to overcome the shortcoming that above-mentioned two kinds of testing equipments exist, specialized equipment a kind of easy to carry, simple to operate, stable and reliable for performance, cheap is provided.
Technical scheme of the present invention is to realize like this, a kind of discharge testing chest is used for the load box of accumulator cell charging and discharging and silicon controlled rectifier, include the indication of power consumption resistance unit piece, AC-DC switch, electric current, voltage table and bright lamp, control circuit is formed, its special character is that AC-DC switch, voltage transitions button and indicating instrument are installed on the panel of chamber, power consumption resistance unit piece all arrange be installed in can be movable epoxy insulation offset plate frame on, the exhaust fan of power supply resistance cell block heat radiation and the A.C. contactor of connection electrical resistance cell block being housed in the case.
The contact of the A.C. contactor in the technical scheme can change the number in parallel of the resistance unit in the circuit, with the constant-current discharge of the battery pack that satisfies the different voltages of test and the needs of rectifier test; Cabinet and epoxy insulation offset plate frame by two web joints together with bolted splice, wherein one is insulcrete, another piece for the conduction connection strap; Power consumption resistance unit piece is that electric furnace heating wire is burnt on the insulation ceramic tile, forms different loads by change-over circuit.
Now describe the embodiment of the invention in conjunction with the accompanying drawings in detail:
