Description
Technical field:
The utility model and a kind of measurement mechanism, particularly relate to a kind of insulation aided measurement device.
Background technology:
Along with the fast development of national economy and the raising year by year of people's living standard, the demand of people to electricity suddenly increases.Meanwhile, owing to having a power failure, leaking electricity, and line insulation fault causes electric shock, electrical fire accident also increases severely thereupon, constitutes serious threat to the security of the lives and property of people.In order to the safety and reliability that strengthening system is powered, various countries launch respectively standard, clear stipulaties will adopt local I T distribution system (also known as insulating power supply system) to power in some important places, and is equipped with insulation monitoring and warning device to monitor the insulation status of IT system.The price of external insulation monitoring and warning device can be in any more all the time, and domestic product is little, and technical merit is limited.。
Insulation monitoring is that a kind of state of insulation for DC power system bus and branch road carries out detection real-time online and the device of management.Safety and EMC meet CE certification.Be widely used in all size electric operating power supply system, solar photovoltaic grid-connection system, direct-current remote feeding power system, HVDC high-voltage direct current (DC) power system state of insulation detection with management in.
The method of existing detection mainly contains bridge balance principle and low-frequency acquisition principle.Be widely used according to the insulation monitoring and warning device that bridge balance principle realizes, but it can not detect the situation when insulation of straight-flow system positive and negative electrode declines on an equal basis; Even if insulation monitoring and warning device is reported to the police, system insulation resistance size over the ground directly can not be obtained.It is a kind of new method adopted in recent years by low-frequency acquisition principle detection of ground faults, but its stake resistance that can detect is by the restriction of straight-flow system distributed capacitance over the ground, and low-frequency ac signal is easily by extraneous interference, the low-frequency ac signal injected in addition increases the ripple coefficient of voltage of straight-flow system.Visible, all there is some defects being difficult to overcome in bridge balance principle and low-frequency acquisition principle.
Utility model content:
In order to solve the problem, the utility model provides a kind of technical scheme of simple and practical, effective measurement insulation parameter:
A kind of insulation aided measurement device, comprises instrument foundation, roller, bracket, insulated lift strut, electrode supporting bar, air switch, tank.Instrument foundation is the built-in pressure regulator of rectangular parallelepiped, reometer, voltage table, direct current instrument transformer, timer, alarm, bracket is arranged on instrument foundation top, insulated lift bar is arranged on bracket one end, electrode supporting bar has the circular hole of 2-3 electrode insertion, electrode inserts in circular hole successively, one end of electrode supporting bar is welded on the top of insulated lift support bar, and tank is placed on bracket.
As preferably, high-voltage connection terminal is equipped with at insulated lift strut top.
As preferably, sink top is equipped with leakage measuring instrumentation connection terminal.
As preferably, measure connection terminal and the voltage table in instrument foundation, pressure regulator is in parallel, connect with reometer, air switch, direct current instrument transformer, alarm is connected on circuit terminal.
As preferably, roller is arranged on instrument foundation bottom, and roller is universal wheel.
The beneficial effects of the utility model are:
(1) the utility model changes lift insulation brace rod into by traditional fixed insulation strut, makes tester change insulator convenient.
(2) the utility model increases direct current instrument transformer, and namely major loop unbalanced bridge detects total insulation resistance, and branch road direct current instrument transformer can detect that the end is which has occurred insulating reducing, and improves test speed.
Accompanying drawing illustrates:
Fig. 1 is Facad structure figure of the present utility model;
Fig. 2 is vertical view of the present utility model.
Embodiment:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1-2, roller 1 is arranged on bottom instrument foundation 2, bracket 3 is arranged on the top of instrument foundation 2, insulated lift strut 4 is arranged on one end of bracket 3, one end of electrode supporting bar 5 is welded on the top of insulated lift strut 4, by in the circular hole of electrode stem a electrode insertion support bar 5, tank 6 is placed on bracket 3, during use, the insulator such as insulated shoes or insulating glove adding water is put into tank 6, insulating blanked clamper on insulator electrode stem is clamped, insulator upper port can not be got wet and be kept dry, to fall in the water that electrode stem a stretches in insulator by insulated lift strut 4 screwing bolts and to put into tank 6.The high-voltage connection terminal of 220V electric source line interface with the top of insulated lift bar 4 is connected, the leakage measuring instrumentation connection terminal of tank 6 upper port is connected with the instrument one_to_one corresponding in instrument foundation 2, by sink box 6 ground connection, by all instrument resets, access voltage, open air switch 7, rotate pressure regulator b handwheel, watch voltage table c attentively, the change of reometer d, boost with the rate of rise of 10V per second, when being raised to required magnitude of voltage, the button pressing timer e starts timing, and pay close attention to the situation of insulator, in measuring process, if leakage current is greater than setting, insulator is breakdown, air switch 7 disconnects automatically, direct current instrument transformer f on branch road can detect that the insulation of that road reduces and opens alarm g and report to the police, cut off the electricity supply, rise insulated lift strut 4 and take off breakdown insulator, and then carry out boost operations, reach assigned voltage and pressure-resistant time and leakage current is not more than setting, alarm is not reported to the police, explanation product is qualified, otherwise it is defective.When test zone changed by needs, next insulator test can be carried out by random mobile insulation measuring apparatus platform, very convenient to use, greatly enhance testing efficiency.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
