Description

A kind of analogue loading device of Long-distance Control

Technical field

The utility model relates to a kind of load device, in particular to a kind of analogue loading device that can realize Long-distance Control.

Background technology

Along with China's fast development of economy in recent years, all trades and professions are for reducing and avoiding the economic loss of bringing to enterprise because having a power failure in the safety in production operational process, and the homogeneous phase second wife is for emergency power system.In order to guarantee the reliability of emergency power system, need to regularly be detected and be safeguarded accordingly emergency power system with fictitious load.At present, general electronic load can only complete the simple test project of low-power load capacity, and most PTC elements that adopt are as load, and the power control accuracy is poor, can not well meet maintenance and the acceptance requirement of every profession and trade to back-up source.For big-and-middle-sized emergency power system, Chang Yin does not have corresponding checkout equipment to carry out simulation test, and makes these big-and-middle-sized emergency power systems exist the potential safety hazard that degree is different.

The utility model content

The purpose of this utility model is to provide a kind of analogue loading device of Long-distance Control, this device can carry out simulation test to the emergency power system of different scales, and not only data accurately and reliably, can also be carried out long-distance intelligent control, avoid the direct operating of contacts of human body, strengthened the security of controlling.

For achieving the above object, the utility model is taked following technical scheme:

A kind of analogue loading device of Long-distance Control, comprise shell, be provided with in the enclosure power switch and wave filter, it is characterized in that, described power switch is electrically connected to wave filter, wave filter is electrically connected to the first transformer and the second transformer respectively, the first transformer all is connected with single-chip microcomputer with the second transformer, single-chip microcomputer also is connected with the control end of solid-state relay, described solid-state relay also is connected with load, copper bar is installed on solid-state relay to power to solid-state relay, described copper bar is connected with isolating switch through the copper bar wire, be provided with current transformer outside the copper bar wire, current transformer is connected with the Multifunctional power energy data acquisition unit, described Multifunctional power energy data acquisition unit and single-chip microcomputer communicate, single-chip microcomputer is connected with display screen with the output data, single-chip microcomputer also communicates with host computer.

Described solid-state relay is the controllable silicon solid-state relay and is arranged on heat radiator.

Described load is the pure resistive NI-G resistance of column, and the load outside is by the stainless-steel tube sealing, and the inside is filled by magnesium oxide.

In described load place, cooling fan is installed.

Described cooling fan is axial flow blower.

From above-mentioned technical scheme, can find out, single-chip microcomputer is accepted the host computer instruction, controlling solid-state relay selects different loads to be tested as required, by current transformer, produced after induction current by the Multifunctional power energy data acquisition unit data acquisition, then pass to single-chip microcomputer, export to display screen by single-chip microcomputer again, cooling fan can efficiently radiates heat, the normal operation of assurance system.Whole device is controlled by host computer, does not need human body directly to contact, and the simulation test data that obtain are accurately reliable.
