Description

A kind of novel overvoltage monitoring device surge suppression cabinet device

Technical field:

This utility model relates to power electronic product apparatus field, concretely relates to a kind of novel the most electric Pressure monitoring surge suppression cabinet device.

Background technology:

In power system, overvoltage monitoring device surge suppression cabinet uses ratio wide, and process is being detected and used In, system earth fault often occurs, reverse capacitive earth current be back to by voltage transformer be System easily causes voltage transformer saturated, be susceptible to ferromagnetic resonance and voltage transformer burns blast etc. Major accident, the overvoltage monitoring device surge suppression cabinet of traditional structure uses fixing isolation knife, needs operator Member operates through row switching input great strength moment, makes high voltage isolator put into and exit, and is System generally requires the single metering cabinet of configuration, occupied ground and increase fund, and present power system is to pass through Install the suppression of special monoblock type additional and add metering handcart overvoltage monitoring device surge suppression cabinet to solve problems.

But the overvoltage monitoring device surge suppression cabinet of prior art has the disadvantage that:

1, easily cause edge of a knife phenomenon of arc discharge in operation and without arc-control device, easily burn the edge of a knife, even Cause alternate and relative ground circuit fault.

2, operation need use great strength and just can carry out switching operation, operation inconvenience.

3, the middle-placed switch cabinet for the adaptation fixed isolation knife of installation need to create a collection of non-to cabinet through row transformation Mark cabinet, has clearly disadvantageous in safety and economies reverse side, is unfavorable for that on-the-spot power distribution room is attractive in appearance and first The exchange of device.

Utility model content:

Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that Yi Zhongxin Type overvoltage monitoring device surge suppression cabinet device, this device uses the suppression of middle special monoblock type to add metering hands Car replaces the most general fixed disconnecting switch, utilizes its rocking arm rotational lead screw jacking and mould of deactivating Formula facilitates site operation personnel to put into and exits special monoblock type and suppresses to add leading between metering handcart and main bus-bar Disconnected, this brand-new frame mode can be greatly reinforced motility and the safety of operation, by mutual induction of voltage Device summation current transformer is collectively arranged in a handcart, it is ensured that in the overall style of cabinet and power distribution room its Remaining middle breaker cabinet keeps consistent, and can utilize original chopper transfer dolly in power distribution room, reduces The wasting of resources, may replace original contact cabinet or incoming line cabinet, and reduces high voltage isolator in use The dangerous fault that when ineffective activity and break-make, phenomenon of arc discharge causes.

Technical problem to be solved in the utility model uses following technical scheme to realize:

A kind of novel overvoltage monitoring device surge suppression cabinet device, including cabinet, suppression cabinet controller, suppression Add metering handcart, single-phase potential transformer, high-tension fuse, single-phase intelligent switch, current transformer and Surge suppression device, it is characterised in that:

Described suppression cabinet controller is arranged on cabinet inner upper end side, and described suppression adds metering handcart and arranges Being arranged in the middle part of cabinet, described suppression adds metering handcart top and installs current transformer, and bottom is installed single-phase Voltage transformer, described single-phase potential transformer high voltage input terminal is by copper bar with high-tension fuse lower end even Connecing, described single-phase potential transformer high-voltage output end is connected with single-phase intelligent switch, and described single-phase intelligent is opened Close outfan and surge suppression device lower end is arranged by cable with being connected to handcart.

The beneficial effects of the utility model are: a kind of novel overvoltage monitoring device surge suppression cabinet device, this dress Put the version changing conventional overvoltage monitoring device surge suppression cabinet, use the suppression of middle special monoblock type Add metering handcart and replace the most general fixed disconnecting switch, it is possible to ensure the rigidity of structure, intensity and Stability, increases the motility of device and exchanges usability, reducing the wasting of resources.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention:

For the technological means making this utility model realize, creation characteristic, reach purpose and be prone to bright with effect White understanding, below in conjunction with being specifically illustrating, is expanded on further this utility model.

As it is shown in figure 1, a kind of novel overvoltage monitoring device surge suppression cabinet, control including cabinet 1, suppression cabinet Device 2, suppression add metering handcart 3, single-phase potential transformer 4, high-tension fuse 5, single-phase intelligent switch 6, Current transformer 7 and surge suppression device 8, it is characterised in that:

Described suppression cabinet controller 2 is arranged on cabinet 1 inner upper end side, and described suppression adds metering handcart 3 Setting is arranged in the middle part of cabinet 1, and described suppression adds metering handcart 3 top and installs current transformer 7, bottom Installing single-phase potential transformer 4, described single-phase potential transformer 4 high voltage input terminal 41 is by copper bar and height Pressure fuse 5 lower end connects, and described single-phase potential transformer 4 high-voltage output end 42 is by after cable short circuit It is connected respectively to single-phase intelligent and switchs 6 inputs and surge suppression device 8 upper end, described single-phase intelligent switch 6 Outfan and surge suppression device 8 lower end arrange 9 with being connected to handcart by cable.

Of the present utility model ultimate principle and principal character and of the present utility model excellent have more than been shown and described Point.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-mentioned Principle of the present utility model is simply described, without departing from this utility model described in embodiment and description On the premise of spirit and scope, this utility model also has various changes and modifications, these changes and improvements In the range of both falling within claimed this utility model.This utility model claims scope by appended power Profit claim and equivalent thereof define.
