Description
Technical field
The present invention relates to a kind of sensor, particularly relate to the sensor of a kind of charged display.
Technical background
Along with being continuously increased and each department of domestic electrical industrial development, power station and generating equipment
The transformation of urban and rural power grids, uses substantial amounts of switch cubicle to want " five prevent " that currently use switch cubicle
Asking increasingly stricter, high voltage display device, as one of " five prevent ", is related to operator
Member and the life security of maintainer, directly influence the safety of electricity consumption.
The structure of existing charged display sensor for bury an electric capacity 12 in the middle part of insulator 2 underground,
One pole of electric capacity is connected to embed the terminals 13 of insulator；Another pole is connected on sensor
The upper flange of end 11, connects high voltage bus by upper flange and is thus connected to high voltage bus, specifically
Structural representation is as shown in Figure 1.High-voltage charge display device is that one is directly installed on indoor high-voltage
On electrical complete equipment, intuitively demonstrate that electrical equipment is whether with the indicative peace of working voltage
Full device.When equipment is with working voltage, this display display window flashes, and warns people
High pressure equipment charged, without electricity time then without indicate.This equipment series need to pass with charged display device
Sensor supports the use, and utilizes the electric capacity in sensor internal core rod type electric capacity and electrification display,
Connect into series connection pressure divider circuit, therefrom extract the voltage signal from high tension loop, as charged
Display drive signal source.Principle as in figure 2 it is shown, sensor upper flange receives high voltage bus,
Electric capacity is connected to high voltage bus by upper flange, and the electric capacity other end is connected to charged by terminals
Display, forms a charged display device.
High-voltage charge display device is integrated in Intelligent operation control device of switch cabinet by a wide range of and open at present
Closing in cabinet intelligent display device, such device is widely used in high-tension switch cabinet.And it is present big
Partial high pressure switch cubicle is maintenance after cabinet, needs to install electrification display at back door, after monitor rack
Electrification in high voltage situation in cable vault, does not open back door under warning people's electriferous state, in case
Mistakenly entering into charged compartment gets an electric shock casualty accident every, initiation personnel.This type of switch cubicle major part is equiped with
Intelligent operation control device of switch cabinet or Intelligent switch cabinet display device, owing to such device is integrated with out
The merits such as the pass operation of cabinet, on off state show, Temperature and Humidity Control, charged display, voice reminder
Can, determine this device and must be loaded on instrument door before cabinet, then after cabinet, just must separately install 1 band
Electricity display, occurs that 2 charged display devices monitor same point charged state.The most general just
Solution has two kinds: a kind of for putting 1 sensor of increase at this, this kind of scheme exists as follows
Defect: the 1. sensor increased ties up installing space, adds installation workload and difficulty；2.
The sensor increased need to connect a copper bar, adds copper bar and the cost of sensor own.Another kind of
It is 2 charged display devices of 1 sensor strip, is illustrated in fig. 3 shown below, is embedded in sensor
Electric capacity C1 is connected to high voltage bus by upper flange, and the electric capacity C1 other end is connected by terminals
Two electrification displays are respectively electrification display 1 and electrification display 2, thus form two
Charged display device:
This kind of scheme has following defects that owing to electrification display is that employing principle of capacitive divider is
Charged display lamp provide power supply, the A point in upper figure to the earth capacitance be C2+C3, again by
Magnitude of voltage in capacitance partial pressure is inversely proportional to its capacitance, therefore A point is to the magnitude of voltage ratio biography of the earth
The magnitude of voltage that sensor individually connects 1 electrification display is little, and this is accomplished by electrification display
Portion's resistance is adjusted to suitable numerical value, and charged display lamp could be bright.Owing to electrification display is standard
Changing product, manufacturer is numerous, and the internal resistance of each producer electrification display is different.Cause
And this kind of scheme often occurs electrification display to show abnormality, easily cause mistakenly entering into charged
Interval accident.
Summary of the invention
For the deficiencies in the prior art, the technical problem to be solved in the present invention is: provide one peace
Quan Xingqiang, be prone to processing, low cost, be not take up extra mounting space, display function-stable,
Can solve the problem that two charged display devices monitor the charged display sensor of same electriferous state.
For solving above-mentioned prior art problem, the technical solution used in the present invention is: a kind of charged
Display sensor, including: outside is provided with the cluster parachute of the alternate poured with epoxy resin of several sizes
Insulator, upper flange, lower flange, also include: the first electric capacity, the second electric capacity, the first wiring
End, the second terminals, described first electric capacity and the second electric capacity are embedded in the middle part of insulator, described
First terminals and the second terminals embed on the downside of insulator；Described first electric capacity bottom crown and
One terminals are connected, and the second electric capacity bottom crown and the second terminals are connected；Described first electricity
The top crown held is connected to upper flange after being connected with the top crown of described second electric capacity.
Preferably, described first electric capacity and described second electric capacity are core rod type electric capacity.
Preferably, described first electric capacity and described second electric capacity are for being embedded in insulation side by side
In the middle part of son.
Preferably, described insulator bottom arranges connecting groove, described first terminals and described
Two terminals embed in connecting groove.
Having the technical effect that the present invention obtains is not changing outside original tradition charged display sensor
In the case of shape and mounting means, two electric capacity can be buried underground by interior insulator, effectively
Solve two charged display devices and monitor same point electriferous state, at this connection two, show dress
The working sensor put is stable, circuit connects simple, safely and effectively.
