Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of to carry external electric power storage energy storage device Distribution transformer load recorder, it increased the supply line of accumulator all the way outside mains-supplied, ensure that and match somebody with somebody Piezoelectric transformer load recorder keeps recording for the detection of transformator data when power-off risk is met with.
A kind of technical scheme for realizing above-mentioned purpose is:A kind of distribution transformer load with external electric power storage energy storage device Monitor, including accumulator box and load recorder;
Power-off siren, GPRS communication modules, alternating current-direct current automatic switchover device and load note is provided with the load recorder Record device;Mains-supplied accesses load recorder, is connected with the power-off siren;The GPRS communication modules are warned with the power-off Report device connection;The alternating current-direct current automatic switchover device is connected with the power-off siren and the accumulator box respectively;The load Recorder is connected with the outfan of the alternating current-direct current automatic switchover device.
Further, an alarm buzzer is provided with load recorder, and the alarm buzzer is warned with the power-off Report device connection.
Further, an antenna connecting hole, an external communication antenna is offered on the top surface of the load recorder It is connected with the GPRS communication module.
Further, an alternating current-direct current MTS is provided with the alternating current-direct current automatic switchover device.
Further, independent accumulator is provided with the power-off siren.
Further, the accumulator box is connected with one piece of solar energy photovoltaic panel, in the accumulator box is provided with the sun Can photovoltaic panel electric power controller.
A kind of distribution transformer load recorder with external electric power storage energy storage device of the present utility model, in distribution transformer Device load recorder increased accumulator direct current supply all the way, while Alternating Current Power Supply is connected with power-off siren, then by two-way Power supply accesses automatic AC/DC changeover switch simultaneously, realizes that the automatic alarm and automatic direct of Alternating Current Power Supply power-off are powered with this and turns Change, it is ensured that for the electric power monitoring of transformator is not affected by power supply state, and by converting equipment or the electric power of mains-supplied Obstacle notifies backstage maintainer in time, lifts the overhaul efficiency for power equipment with this.
Description of the drawings
Fig. 1 is a kind of structure of distribution transformer load recorder with external electric power storage energy storage device of the present utility model Schematic diagram.
Specific embodiment
In order to be able to preferably understand to the technical solution of the utility model, below by specifically embodiment and combine Accompanying drawing is described in detail:
Refer to Fig. 1, a kind of distribution transformer load recorder with external electric power storage energy storage device of the present utility model, Including accumulator box 2 and load recorder 1.
Power-off siren 11, GPRS communication modules 12, alternating current-direct current automatic switchover device 13 and load are provided with load recorder 1 Recorder 14.Mains-supplied 3 accesses load recorder 1, is connected 1 with power-off siren, and mains-supplied 3 is load recorder 1 One phase of distribution transformer low-pressure side to be measured.GPRS communication modules 12 are connected 11 with power-off siren, the top of load recorder 1 An antenna connecting hole is offered on face, an external communication antenna 16 is connected with GPRS communication module 12, to ensure that signal is passed Pass.Alternating current-direct current automatic switchover device 13 is connected with power-off siren 11 and accumulator box 2 respectively.Load record device 14 is with alternating current-direct current certainly The outfan connection of dynamic switch 13.Independent accumulator is provided with power-off siren 11, is allowed to run and work be not subject to The impact of external environment, it is ensured which stablizes standby.
In the normal mode of operation, be measured piezoelectric transformer is monitored and recorded to load record device 14 by mains-supplied The information such as three-phase voltage, electric current, active energy, capacity of idle power.There is situation in mains-supplied 3, or when transformator produces failure When, the circuit of 3 side of mains-supplied cannot be opened a way for electric forming, and now power-off siren connection 1 produces alarm signal, and passes through Power cut-off information is sent to dispatching control center by GPRS communication systems, while controlling alternating current-direct current automatic switchover device 13 switches to exchange Powering mode, is powered to load recorder 1 by accumulator box 2, to realize treating being measured the continual and steady electricity of piezoelectric transformer Monitoring.
1 an alarm buzzer 15 can be provided with load recorder, alarm buzzer 15 is connected with power-off siren 11 Connect.When there is the loss of power accident, power-off alarm 11 sends signal to alarm buzzer 15, and control alarm buzzer 15 starts, On-site personnel can be directly pointed out to overhaul distribution transformer without the need for back-end data monitoring.
An alternating current-direct current MTS is provided with alternating current-direct current automatic switchover device 13.Transformation facility is being overhauled When needing to turn off operation to circuit, can manually by the Working mode set of load recorder 1 be direct current supply pattern, with protect Demonstrate,prove in maintenance, holding is continued to monitor to becoming electrical equipment.
