Abstract
An indoor high voltage electrified display device comprises an epoxy resin vacuum pouring body, wherein an upper fixed flange, a lower fixed flange and three high voltage signal sampling points are arranged on the vacuum pouring body. The device is characterized in that the three high voltage signal sampling points of the vacuum pouring body are respectively provided with inductive sheets, the inductive sheets are connected with a control circuit through wires, and the control circuit comprises a high voltage signal processing circuit, a voltage stabilizing circuit and an executive circuit. Compared with the prior art, the device adopts the inductive sheets for sampling in an inductive mode, thereby omitting a capacity core rod, reducing the manufacturing cost, obtaining high voltage signals through utilizing the inductive sheets, controlling a relay to work after being processed, and realizing the functions of displaying and locking.
Description
[technical field]
The utility model belongs to a kind of indoor high-voltage chargeding displaing device.
[background technology]
Indoor high-voltage chargeding displaing device is 3.6kV, 7.2kV, 12kV and 40.5kV in rated voltage, frequency is in the indoor high-voltage electrical equipment of 50Hz, be used to reflect the charged state of high tension loop on the one hand, on the other hand, to realize forced blocking, prevent mistakenly entering charged chamber, moreover supporting, improve the anti-error performance of auxiliary products with disconnector, grounding switch.Before the utility model was made, existing indoor high-voltage chargeding displaing device was made of voltage sensor and voltage indicator two parts.The last mounting flange that sensor is poured into an integrated entity by epoxide resin vacuum, the electric capacity plug, second decimation end and following mounting flange are formed, there are the following problems in actual applications for the indoor high-voltage chargeding displaing device of this structure: utilize the electric capacity plug and be attached thereto the lead that connects and transmit high-voltage signal to display device, high-voltage signal is after the display device processing of circuit, send indicator signal to relay, pilot relay work and finishing the work, problem is that expensive electric capacity plug has caused the production cost of whole display device higher, and the high more problem of rated voltage is outstanding more, has had a strong impact on economic benefit of enterprises.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of indoor high-voltage chargeding displaing device, and this device has the repertoire of existing display device, and simple in structure, production cost is low.
For achieving the above object, following technical scheme has been adopted in this practicality: the structure of this indoor high-voltage chargeding displaing device, comprise the epoxide resin vacuum pour mass, contain mounting flange and following mounting flange on the vacuum pouring body, and three high voltage signal sampling points, it is characterized in that: three high voltage signal sampling points at described vacuum pouring body are respectively equipped with sensing chip, and sensing chip is connected with control circuit through lead; Control circuit is made of high-voltage signal treatment circuit, mu balanced circuit and executive circuit.
Beneficial effect: compared with prior art, the utility model adopts sensing chip induction sampling, thereby can omit the electric capacity plug, reduces production costs, and the high-voltage signal that it utilizes sensing chip to obtain, pilot relay work after treatment, realization shows, blocking function.
[description of drawings]
Fig. 1 is the circuit theory diagrams of an embodiment of the utility model.
[embodiment]
Referring to Fig. 1.Responding to the high-voltage signal that gets off by sensing chip A, B, C triggers by T1, T4, T2, T5, the control circuit that T3, T6 etc. form is worked by the conducting of high-voltage signal treatment circuit, make LED1, LED2, three luminotrons of LED3 luminous, show high pressure, simultaneously, trigger T8 conducting work by the plateau levels after 7805 voltage stabilizings of mu balanced circuit integrated package, the T9 triode is ended, and the contact triggered electromagnetic lock of relay J can not be opened.If there is not high pressure, then sensing chip does not have induced signal, T1, T4, not conducting of the composite amplifier work that T2, T5, T3, T6 form, LED1, LED2, three luminotrons of LED3 are not luminous, do not show high pressure, not conducting of T8 work makes the T9 triode conducting of executive circuit, and the contact triggered electromagnetic lock of relay J can be opened.In addition, the AN button has self-checking function, press AN, T1, T4, T2, T5, the composite amplifier conducting work that T3, T6 form, make LED1, LED2, three luminotrons of LED3 luminous, T8 conducting work ends the T9 triode, the contact triggered electromagnetic lock of relay J can not be opened, and illustrates that the demonstration of display device and blocking function are normal.
