Abstract
The utility model discloses a grounding state monitoring device for electrical equipment and grounding network of a transformer station, which comprises a grounding resistance testing instrument. A grounding terminal of the electrical equipment and grounding strap iron of the grounding network are connected with one end of the grounding resistance testing instrument through leads, and the other end of the grounding resistance testing equipment is connected with a grounding rod through a lead. The grounding state monitoring device for the electrical equipment and grounding network of the transformer station has the following advantages: simple structure, high operation convenience, and capability of causing an operator to understand grounding resistance value of the electrical equipment and the grounding network at any time for quickly determining whether the grounding is reliable and good, and capability of realizing real-time monitoring on the grounding state of the electrical equipment and the grounding network.
Description
Technical field
The utility model relates to a kind of monitoring equipment, especially relates to a kind of Substation Electric Equipment, Grounding state monitoring apparatus.
Background technology
At the substation operation scene to electrical equipment such as isolating switch, disconnector etc. divide, during closing operation, when particularly needing electrical equipment is carried out interruption maintenance, all will carry out the ground connection operation to equipment after separating brake, before combined floodgate, ground wire is to guarantee that the staff avoids the most direct safeguard measure of electric shock injury; If the equipment ground line loss is bad or grounding connection is unreliable, can cause serious injury to operating personnel, equipment is done great damage.Grounded screen is as transformer station's alternating current-direct current equipment ground and thunder proof protection ground, and operation plays an important role to security of system.Grounded screen and ground connection band iron all can have corrosion in various degree every year, and the stake resistance of grounding apparatus is changed, and stake resistance exceeds normal range, can do great damage to power system device.
In order to guarantee various electrical equipments and grounded screen safe and reliable operation in the rules scope, at present, the power transformation operation personnel are measurement inspections of regularly carrying out in accordance with regulations stake resistance.But can not make electrical equipment and grounded screen be in the control state fully.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of Substation Electric Equipment, Grounding state monitoring apparatus, and it can implement immediately monitoring to the grounding resistance of electrical equipment grounding line, grounded screen, and reliability is high.
For achieving the above object, the utility model adopts following technical scheme:
A kind of Substation Electric Equipment, Grounding state monitoring apparatus, it comprises earth resistance tester, electrical equipment grounding terminal, Grounding band iron are connected with earth resistance tester one end by wire, and the earth resistance tester other end is connected with ground rod by wire.
Owing to adopting technical scheme as above, the utlity model has following superiority:
This Substation Electric Equipment, Grounding state monitoring apparatus, it is simple in structure, easy to operate, the numerical value that operating personnel can show by earth resistance tester, understand at any time the grounding resistance of electrical equipment, grounded screen, judge fast ground connection whether reliably, well, realization is to electrical equipment, Grounding state immediately monitoring.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: the 1-shaft tower; 2-ground connection band iron; The 3-earth resistance tester; The 4-ground rod.
Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is described in further detail below by embodiment.
As shown in Figure 1, this Substation Electric Equipment, Grounding state monitoring apparatus, it comprises earth resistance tester 3, and Grounding band iron 2 is connected with earth resistance tester 3 one ends by wire, and the earth resistance tester other end is connected with ground rod 4 by wire.
When to Substation Electric Equipment, as the isolating switch on shaft tower 1 divide, when closing operation or interruption maintenance, the circuit interrupter grounding terminal is connected with earth resistance tester one end by wire, the earth resistance tester other end is connected with ground rod by wire, after the earth resistance tester energising, measure circuit interrupter grounding resistance, according to the resistance that earth resistance tester shows, can judge that whether reliably, well ground connection.
